Hi John
I can endorse your view on the Spade after testing our new 35kg Spade this year along the Norwegian coastline and Svalbard. We did drag twice since April:
– on the first drop in Svalbard(Hornsund south side..); although we had a 4/1 scope in about 5-6m of water, it was my bad for backing down too fast on it when setting. Kept an eye on it and sure enough we started slooowly pulling Zs 2 hrs later when the 30 knotter started coming through. Kelp. Lots of it.
– Second time was in the Lofotens, super shifty from 90 more than degrees angles, 5-35kts, again 4/1 scope. Tricky for any anchor given the directions and strenght of gusts. However, when the Spade drags on the rare occasion, it does it very ‘sweetly’. That only helps with the piece of mind that’s for sure.
I hope this post doesn’t put me in even more trouble with Peter Smith. Met the man up here this summer, I drooled over Kiwi Roa (just like anybody would..) but had lots of laughs and shared a few good yarns with the legend.

I just invested in a 20kg spade. The first thing to strike me is the way in which this anchor wants to self right. I don’t store the anchor on the roller when at sea (or on my swinging mooring for that matter) so intended to store the spade lashed on it’s side where the CQR used to lie. Its almost as though the thing is alive with its desire to position itself in preparation for penetrating the ground. I haven’t actually used it yet as I’m still trying to sort out the shackle arrangement but fingers crossed it will serve me well.


Nit picking I know, but According to SV Panope, the Spade has 42% tip weight ratio. While the Mantus has 50%

Either way they both seem like great anchors



Sailing Panope also selected a Spade as his main anchor because of it’s robustness. I am not an experienced sailor at all! just an avid internet researcher, And I can imagine that the roll bar may possibly prevent penetration in deep kelp beds possibly. But the thing that appealed to me most about a Mantus is its amazingly fast resetting ability in low scopes on hard turn arounds. It just made me feel like if the winds or currents made a 180 overnight I wouldn’t worry as much about it dragging. (same reason we decided against a Rocna although we considered the Vulcan due to it’s spade design)

My thoughts on the possibly weak structure of the Mantus, I’m sure the boat would not shear the metal, If anything happened it would just bend. In which point upon retrieval I would think to myself… Time for a replacement. (So not a catastrophic result)

Full disclosure: After contacting Mantus, they sponsored us our anchor because of our YouTube channel.

I’m sure I would sleep just as well with a Spade as well. (not that I sleep very well at anchor yet) 🙂

I am now using a SPADE but on my previous boat (catalina 30) had a rocna. It was setting so well that I guess I had become complacent. Anchoring off Saquish neck at the entrance of Plymouth bay, I had a good night and went for a stroll on the beach. A gentleman walking there pointed to my boat, which was noticeably dragging slowly in the current. I scampered back to hightail off. The current was very, very strong: it was actually pushing the boat so hard against the rode that I had to use the engine to swing the boat in order to retrieve the anchor (no windlass, all by hand). My analysis (beyond the poor anchoring choice) is that the strong current at this place somehow loosens the sand. But I can testify that the rocna was fighting it and to this day am happy for the slow, slow drag.

Richard Dykiel

Ah yes, actually. I had anchored late at night and the issue occurred early morning. So definitely after 1 tide cycle.

Bill Balme

I like the yellow paint! It allows me to see how much crap there is on it while still in the water and I get rid of all of it by shaking the chain with the boat hook. The paint lasted through 18 months continuous usage before really wearing out, but we gave it another coat (Neon green Rustoleum this time!) a couple of months ago and we’re back to loving it!
Love the anchor.

Shane Brooker

I just bought a SPADE 140 to replace my 45lb CQR. I went one size up based on their estimated sizing scale for a 46′ 17ton… was set on a ROCNA but based on your comments and observations I changed my mind. Only complaint is it does not sit on my roller assembly too well and I will have to modify, but looking forward to using it.

Charles L Starke

We love the 99 lb Spade after switching from (and dragging with) an 88 lb Rocna. We also carry the larger 66 lb aluminum Spade as a storm anchor and the Fortress 37 as a kedge. Very happy with the choices and haven’t dragged (yet)! But our anchoring is not as challenging as John’s.
Best wishes,

I just bought a S180 (99Lb) for my 60ft. schooner (50,000 lbs.). This is the correct size recommendation for my boat, but I would have gone up one size but couldn’t fit it properly on my bow. I ordered it direct from Spade I tried ordering it online, but was unable to. I called and the guy who answered the phone took the order and could not have been more helpful or knowledgeable. He said they were having some problems with the website and hoped to have it solved in a few days. It arrived a week later on the day he said it would. All in all a great experience. Also they are having a sale, so I saved a couple hundred bucks!

Marc Dacey

I also bought, based on these sorts of recommendations, a SPADE S140 for our 41 foot steel pilothouse cutter (circa 16 tonnes). Now I just have to source a Beta Marine starter to give it a try…I also have two Fortresses, an FX-37 for kedge and an F-21 for stern, and am keeping a Bruce for “other” duties, as it’s in good shape and I just removed 200 kilos of lead shot trim ballast in anticipation of more chain below.

Dick Stevenson

Hi John and all,
The recent writings on anchors and the size chosen for the given boat gets me wishing to put out a couple of things. My choices reflect the fact that I occasionally end up in marginal anchorages.
I sailed my 40 foot 16 ton boat for 6-7+ years with a 30kg Spade: I loved it but it developed some impressive rust. Spade was good enough to replace it for free: they even allowed me to step up to the 35kg and just pay the difference which I thought was very accommodating of them. I did some figuring back then and felt that the blade area/weight difference etc. probably increased my ground tackles holding power geometrically (30-35%). I consider the 35kg about right now after 2 years with it.
I consider, after anchor design, anchor weight to be far the most potent factor in keeping anchor stuck in the bottom. Choose chain by strength, choose anchors by design, then weight. Putting extra weight on the bow is anathema to many sailors, but the additional weight we are talking about is not a big deal. The bigger problem will be how few boats (rollers and bow structures) are designed for big anchors.

I am very pleased with my Spade anchor. Have used it for 6 seasons now, and never dragged.
There are some problems with rust and this season I had to paint it.
On soft bottoms its important to og back slowly so the anchor have time to go down. It feels like it is not holding properly, but when taking up the anchor in the morning, I have to lift it 2-3 times with the bow to clear it. Its always full of mud or sand when it comes up.
My boat is 10 tonnes and the anchor is 20 kg. Maybe I will go up one size, but has never dragged. Mostly my anchoring takes place in northern Norway.

Hi John,

Agreed that this is a very important characteristic and that the Spade is one of the best if not the best performing in this regard. This goes hand in hand with how much distance you can have to the next obstruction. While I love the short scope abilities of our anchor and utilize them often in very tight spots, if we are expecting weather, we head for a spot with plenty of room to drag while I feel like many people head for very small spots. Some of this may be a holdover from when I worked on much larger vessels and some is likely due to having had to scramble to get underway while dragging multiple times when using old gen anchors. While I still like a lot of space to drag, I have become more comfortable with less space thanks to our anchor’s characteristics, largely related to not suddenly releasing. This has proved handy a few times including just recently when I misjudged and showed up late in the day to an anchorage when expecting weather that night only to find that numerous other boats had picked the same spot. Rather than anchor downwind of other boats, we moved to a smaller less protected spot right next to it and were glad as boats dragged past where we otherwise would have been in the middle of the night.



Hi John,

Regardless of anchor, two things that struck me about your article have to with the value of experience and good seamanship:
1) Knowing you’ve deeply/securely by powering down strongly -and I appreciate the comments added about the backing down rate when setting as anchor types do seem to vary in their ‘preferences’. For me, not only does sitting on higher rpms confirm to me we are set, it lets others anchored around me know as well.
2) Understanding how the type of seabed effects how your set feels -I have limited experience here (but gaining!). Your ‘ball bearing’ gravel comment struck home as we experienced that this summer in a small, tight anchorage that had a deceptively strong toilet bowl current that would change in the wee hours. I awoke to adjust scope as planned, but was instantly alerted to what I was initially considered could be dragging. After staying up on watch for a couple hours over the peak current times, I can confidently say what I was feeling/hearing was the anchor chain resonating as it swept across that ‘ball bearing’ bottom (over a field of 210 degrees). Having confidence in our strong anchor set procedure allowed me the patience to observe. Thanks for sharing your insight and knowledge.

Drew Frye

I see a shackle on the heel of the fluke. What do you use this for? Tripping?

One of my theories for anchor testing is that testers should report the poorest result where the anchor “felt” set. In other words, the poorest set that exceeded reverse thrust. Instead, they report the best set. However, some anchors are consistent, and some are occasionally brilliant but sporadic. I want the anchor that when it feels set, is set.

Your criteria fits well with this. When the anchor begins to move, the drag should remain significant for some distance.

Eric Klem

Hi Drew,

I share your feelings that anchor testing should not just report the best results and needs to given an idea of the distribution. One thing that I found very interesting was to look at the raw data from one of the anchor tests where they had pulled each anchor 5 times. Some anchors were so inconsistent even though they set each time that they were less than 2 standard deviations away from no force which is shocking while others had much narrower spreads. Obviously, 5 data points is too few to draw any conclusions on specific spreads but it did show that it is an important factor that is not properly reported.

My theory on anchoring in general is that it needs to be looked at from a probabilistic viewpoint. Using the expected spread of holding power and load, you can figure out how often you are likely to drag with a given setup. Thankfully, the loads are usually pretty low so dragging is not that common.


Dick Stevenson

Hi Drew,
Yes, that is a very good idea for anchor test reporting: or for any report pertaining to tests of design parameters. I always appreciate your thoughts and contributions. Thanks.
With regard to the shackle on the end of John’s anchor: a suggestion.
I generally abhor trip lines and feel that getting one’s anchor trapped on the bottom is partly technique, but mostly bad luck. I use trip lines when I know of reports of a foul bottom, rarely in other words. That said, I also wished for a plan for when the anchor does become stuck and there is no trip line.
I will describe something I do which can make attaching a trip line easier when the anchor is down and stuck without one. Sometimes the anchor is sitting proud and accessible (say, it is caught on a 2 ton mooring left in years past). It is also possible the anchor is buried deep and/or tangled in a stump or some discarded appliance and getting at the end of the anchor could be difficult or take time. In warmer waters, I would be doing this free diving and only had seconds to attach the trip line, so I wished to make the finding and attaching quick and easy. Even if I put on a tank, and dive gear (say it was quite deep) I would want it easy to attach the trip line.
I also have a shackle on the end of my anchor which may be hard to get to in the seabed or tangled in whatever has you caught. So, attached to this shackle is about 6 feet of nylon 3 strand with an eye on the end and a brightly colored small commercial fishnet float (shaped like a small football, the US game) with a hole going through it. The float is small enough not to interfere with anchoring at all, but large enough to float free above the anchor. In clear water, I can often see the float from on deck if not too deep. All I need to do to attach a trip line is dive down and attach a spring-loaded shackle. Then from deck it is easy to pull the anchor up backwards.
The 6 foot line serves a secondary purpose of always being there to tie the anchor off on the roller.

Anchor designs have pros and cons, but so subtly different between similar designs that any debate is emotional investment more than reality. Your Spade anchor’s slow drag (while backing down) theory didn’t hold true for a catamaran I rescued in Mexico. It was zipping across Bahia de Navidad in 35 knots of wind, with a Spade anchor. Our primary anchor on Totem (Stevens 47) is 33Kg Rocna; and have anchored 523 times (as of today) in 41 countries around the world. Despite the roll bar we’ve not experienced what you say – and let’s just say we’ve been in a lot of different conditions. It could happen I suppose, just as a Spade or Mantus or Mansun Supreme struggling to reset after unsetting from radial direction shift and load. Only once did our Rocna not set – in very thick eel grass of Pittwater Australia, though we’ve anchored in eel grass on other occasions. We’ve dragged 3 times (all very slowly I might add): In Indonesia, Mexico, and Grenada – each time because of unknowable reality on the bottom, such as plastic bags that wrapped the anchor. My point isn’t to say Rocna is the best any more than I believe your Spade is. We would’ve had similar results with ANY of the anchors I’ve mentioned. I’ve used Bruce and CQR in the past, and don’t care for them. Danforth/Fortress are fine in the right bottom, for stern anchor or tandem anchor rig. Technique matter at least as much as the anchor, most of which is simple to enough to learn and understand.

Jamie Gifford

John, I’m glad to hear that the comment section allows other opinions.
You wrote, “the evidence is here” with a link to your article stating “reports” of Rocna issue, but no anecdotes. And surely you know of heard of other anchor drag fails – such as the Spade anchor on the catamaran I mentioned?
You also use the video test to make your point, while stating the test is “albeit in a much more aggressive way than would normally see in the real world”; and, “I have no faith in testing to determine an anchor’s all-around reliability and versatility”. The test was a joke. You can plainly see that the anchor is NOT properly set before reversing pull direction. I’ve seen well set Rocnas, up close (a few hundred times!). Further, the Rocna was the lightest anchor tested and with a short scope of 3.5:1.
Again my point isn’t that a Rocna, Spade, Mantus, etc are clearly better than the others, because that false. Rather I find it worrisome to posit that ANY anchor design is infallible to dragging catastrophe.

Jamie Gifford

Guess, so! A test to show how an anchor resets, when the anchor is not set correctly to begin shows nothing.

Dick Stevenson

Hi Jamie,
I am curious about whether the Spade anchor you report dragging on a catamaran was, in fact, an aluminum Spade. Many catamarans choose aluminum for weight considerations and they have quite different set/holding characteristics than the steel anchors.
I can contribute anecdotal evidence to Rocna’s occasionally not re-setting after a wind shift. Two friends have had that happen to them and 2 others have reported same. Neither, to my knowledge, has changed anchors because of this issue, but I know that at least one considered it. All are wary of it happening again and I know from one, that he will lift and re-set after a significant wind shift.
As someone who occasionally has differing opinions from John, I can certainly attest that the comment section allows for this.
I do not consider the videos of anchor sets “a joke”. Nor do I consider the videos of wind shift re-sets a joke. Especially when repeated tests showed similar results that some anchors did far better than others. I agree that anchor testing is often quite limited in its applicability and inflated in reporting results, but the videos of anchors and their setting etc. I found quite informative and, while not definitive, a good jump forward in ground tackle knowledge base. Especially when test results go hand in hand with anecdotal field reports.
And finally, you emphatically say that no anchor is infallible to a dragging catastrophe. With that, I agree. But I am not sure to whom you are saying that as I have neither heard nor read anyone on this site contending that any anchor is infallible. I believe what is being said by John is that he has never dragged catastrophically. In that I agree. In thousands of anchor sets over the 10 years I have had Spades, I have never dragged. In fact, I do not believe I have even tested the “slow” drag that John has recently written about. I have always stayed put.
I suspect there will be a time when I drag, because that is life on the water, but it has not come yet.
My best, Dick Stevenson, s/v Alchemy

Charles L Starke

I agree wholeheartedly with Dick and John. I found my 88 lb Rocna (on a 40,000 lb Trintella 47) did not set at all if I was going over 1.5 knots, and I dragged twice with a tide shift.
I sold my Rocna and now have a 99 lb Spade and have had no problems.
On my previous boat with a 66 lb aluminum Spade, it took me 1/2 hour of motoring around with bow down and chain up and down, to break free in mud in northwest Rockland Harbor Maine. Boy, was it set! I’m lucky I’m not still there!

Hi Dick – don’t know if the Spade was aluminum or not (and speculation doesn’t answer, it was a big cat). I arrived at the boat and found a big Fortress on the bow, set to go. This set and stopped the dragging. Later, I spoke with the owners, and heard about the anchor brand but not specifics. I remember this one well because of how fast the boat was dragging – really got the heart rate going!
In 10 years sailing Totem (only 523 sets, jeez you move a lot to have thousands in the same 3,650 days!), I’ve seen and assisted in many boat dragging events around the world with all types of anchors, including Spade, Rocna, CQR, Bruce, and even a fisherman anchor. This content that I read makes no mention of any Spade anchor faults. My word, reports of Rocna failures everywhere, including wild speculation regarding a boat lost in Greenland. But no mention of any Spade fail… Those without much experience may interpret this tragically wrong.
Too often, the anchor gets blame when technique is at fault. John is spot on, in explicitly writing about backing down to the point of chain being bar tight. And this is just one small part of technique! Still, focus falls to the anchor. Testing give some information but falls short because of so few variations, to be of real world value. Regarding the video test – how can it possibly have validity showing anchor RESET when the anchor is NOT set to begin with? Please, convince me otherwise! When my anchor is set (which is the goal every time it goes down!) I have to work hard to get it out of the bottom. It doesn’t just pop out and zip along. But then, I haven’t experience the issue “proven” by the test.

Marc Dacey

I’m too green in terms of serious anchoring to comment here save for the observation that I do think technique (the way in which one backs down, sufficient scope, snubbers/bridles, etc.) and having a separate anchor of an opposing type (Spade or Rocna plus Fortress, for instance) is prudent and brings up the likelihood of a successful set. I hope to anchor hundreds of times in order to test this hypothesis more rigorously.


I’m a little late to this discussion as we’ve been out on the boat for the past 4 weeks outside of cell range.

We replaced our 25 Kg Rocna with a 25 Kg Spade (S120) early this year. We have anchored out now approximately 50 nights.

We cruise the waters around Vancouver Island in a Nordic Tug 37 (~ 40 ft LOA & ~22000 lbs or 11 Tonnes) and anchor out as much as we can.

Apart from the yellow paint flaking off the Spade in pretty short order, we have noticed a very significant difference in the setting characteristics of this anchor compared to the Rocna. It sets more quickly and when we power down to confirm the set it does not let go in a pulsatile fashion like the Rocna did. Maybe we should have been more gentle with the Rocna on the initial setting process but the Spade inspires confidence in a way that the Rocna rarely did.

We had at least 2 occasions with the Rocna where we had strong tidal shifts and I was sure we had dragged before resetting. The anchor alarm woke me both times. Both times, I found us sitting in a new position with no evidence of further movement. This is Not science and simply anecdote but these experiences were enough to erode our confidence in the Rocna. We’ve anchored in many of the same spots this season without any issues with the Spade.

In light of the Panope videos of resetting failures, for tight anchorages with menacing rocks, I have taken to doing a second test of our set by backing the boat down in the direction I least want to go to ensure that it will hold on that direction as well.

Bob Miller

After using a CQR with no horror stories for the past 26 years and chatting with the Spade anchor guys at boat shows the past 3 years, we purchased a Spade S120 for our main anchor this summer. Used it on our 5 week cruise to Maine and back. We are very impressed with how quickly it sets and once in, you don’t seem to budge at all. The only disappointment was that a section of galvanizing flaked off on the top of the shank near where the shackle attaches. And then it immediately began to rust. Never had that happen with an anchor before. When we contacted the US distributor, they suggested we coat the anchor with epoxy, offering to send us a kit to do it. Also offered to exchange the entire anchor or just the shank. Fortunately, the shank can be removed and we have it with V & S Galvanizing to get it re-galvanized.

So far, we’re happy with the Spade.


Svein Lamark

I must confess I love the Spade anchors I have got. They never drag. I use a 55 kg and a 20 kg. Unlike many yachtsmen I believe that the length and the weight of the chain is of importance. Some fifty years ago I learned at captains school the formula to calculate this: FN=Ft x sinus alfa. FN is the horisontal force on the anchor along the bottom while Ft is the real pulling force on the anchor and alfa is the angel between the chain and the bottom. Ft will always be bigger than FN. So it is best to have a long chain and a heavy chain. I use 10 m of 1 inch thick chain first, than 60 m of 13 mm chain and in the end I have 200 m of wire. This way i can anchor almost anywhere any weather. The winch can lift 6000 kg pluss another 5000 kg. Sometimes I have lifted with more than 6000 kg to get it free from the bottom. As you may understand I never pull the Spade in to settle it better because of the risk to never get it free again or to brake the chain. This way I sleep well when at anchor.

Dick Stevenson

Hi Svein,
You and John should send pictures of your yard sculptures to Spade. Mercenary that I am, I just sold mine.
Your system clearly works for you but for readers who may not have your experience, I wish to convey a thought. I totally agree with your points with the exception of choosing chain by weight, by length yes, long chain length increases options and allows for ample scope, especially when anchoring deep. But for weight, I would suggest that for best ground tackle effectiveness, weight distribution should go in the anchor and chain should be chosen for strength. Pound for pound, you enhance ground tackle effectiveness by far the most from weight/size in the anchor. Further, in gale conditions and commensurate seas, in my experience, most chain rode (at least that able to be carried reasonably on recreational vessels at reasonable scopes) will become 2-blocked, tight link to link, upon occasion. Chain weight will not much matter on these occasions. When that occurs the dampening effect of catenary will disappear and the load dampening will be borne solely by the snubber.
I suspect your 10m of 1-inch chain right next to the anchor serves to be almost like anchor weight and, as you said, makes the Spade very aggressive. I wonder whether that additional weight in the anchor itself (or at least some of it) would not do the same or better. One would then not have the issue of hauling chain/wire etc. of different diameters/types.
I also feel that, for most of us, backing down on the anchor after letting it settle in for a bit, is wise. I know it enhances my feeling of security and allows me to sleep better. There may be a bit more work in getting it up, but the windlass is up for it. Backing down not only sets the anchor, but gives me a feel for the bottom, which I find helpful.
As always, I find your thoughts/procedures wonderfully stimulating.
My best, Dick Stevenson, s/v Alchemy

Svein Lamark

Hey Dick! I think we agree on this matter, but we both come from different maritime traditions. Mine is the traditional Norwegian influenced by great sailors like the vikings, The Royal Navy and specially Colin Archer. Yours is more what I call The Bermuda Rig tradition. In The Bermuda Rig tradition the anchor, the winch and the chain are placed on the front tip of the boat. From a stability point of view it is not good to put a heavy object at the far end of a boat. So the anchor system has to be as light as possible.
My tradition was based of the vikings and The Royal navys use of a big anchor and a long rope. Eilert Sundts study “On the Ocean” 1864 showed that the death rate among Lofoten fisher men between 15 and 65 years of age was 25%. 1 of 4 died at sea. This dramatic figures started a debate and a clever constructor Colin Archer produced several solutions like safer fishing boats, rescue boats and expedition ships. Archer advised the use of a big and long chain. The chain must be stored around the main mast foot and the winch placed behind the main mast. This way the anchor system would improve the stability of a heavy weather sail ship. Archer was a great success.
As a kid I learned that if the chain swims close to the anchor; it is too light. Change it to something bigger. Than you do not have to use a snubber as the chain will never be straight. I think this is the best and safest way to anchor, but most of our boats are constructed in the Bermuda tradition like yours. Than you and John are right: The Spade of some seize is a formidable solution. If you sail in The Arctic in winter times
I still believe that the recipe of Colin Archer is safer.

Dick Stevenson

Hi Svein,
I always learn something from you. I think another contributing piece is the design evolution over the last century or two of anchors. Way-back-when, anchor design was certainly superior to the rock tied onto the rode, but not by a lot.
Thanks for your reply, Dick

Dick Stevenson

Hi Svein,
Nice to read your contributions again. Not many have wire, but I suspect that you do, indeed, sleep well. My best, Dick Stevenson, s/v Alchemy

John Burton

This is another testimonial for a Spade S80 which I have used for the last 13 seasons with faultless results.
My favourite anchorages on the planet are the coves at the entrance to Endeavour Inlet, Queen Charlotte Sound, Marlborough, New Zealand. The official Cruising Guide says “In the coves leading out to Bottle Rock there is shelter from N to NE winds if pulled close to shore with a stern line, but holding can be difficult”.
Yes , holding is difficult, partly because it’s necessary to drop the anchor in deep water (usually 50-60 feet ) and motor astern close to the shore to be able to row out the stern line(s) . There is still 15 feet of water within 25 feet of the low tide mark. The anchor is being pulled slightly “downhill” towards the shore as the yacht goes astern. And the mud is not the thick gooey type found in shallower depths.
As a consequence, during the first 10 years of my yacht’s life, I persevered with a CQR attempting to anchor in these coves where the anchor rarely set first time – more often requiring 2, 3 or 4 attempts.
Since buying my Spade, the anchor has set first time , every time. Nor has the anchor ever dragged – anywhere – even with the shorter scope ratios that deep water anchorages impose. Most magazine tests seem to conclude that the Rocna should be the anchor of choice but, having read this post and viewed the re-setting failures shown in the SV PANOPE video, I will happily stick with what I’ve got.

Marc Dacey

Just a note that the purchase of my new SPADE S140 was fostered by this site, but it wasn’t cooked to serving temperature until I saw all the relevant S/V Panope videos. Even though I found SPADE the most appropriate choice, his head-to-head testing showed that other types were nearly as good in most situations, and that there were clear problems or shortcomings with some of the older types.

Now, I have to set up a decently sized snubber: I wonder what you think of the “answer” suggested here? Even as a rule of thumb?

Svein Lamark

Thanks Dick! It is when I use the heavy chain that the Spade will dig in so deep. This way the Spade becomes very aggressive. What happens if the Spade is deep in the bottom and the wind turns around? Nothing. I once anchored in a bay open to north. The wind was a SW gale. 2 o’clock in the night the wind turned to N storm. I got up and watched the change. The Spade did not move.
I have also tried to anchor the Spade with a light 8 mm chain or just a rope. Often this is good enough, but the Spade will not dig in so deep and it does not drag.
Based on my experience I have put all my old anchors ashore (Bruce, Danforth etc.) and made a sculpture of them in my garden. If you visit my home again I will show you my anchor sculpture called maritime history. You are welcome.

Dick Stevenson

Hi Marc,
Lots of in depth analysis there, but they end up with larger diameter snubbers than I prefer. Just to be clear, snubbers, in my use of the word, are for use when I am on the boat or off on a day hike. Longer periods and an un-attended boat start to move toward mooring pennants, a quite different challenge.
My anchor snubber (40 foot boat, 16 ton live aboard loaded) is a 35 foot 7/16 inch piece of high quality nylon 3 strand. It stretches like a rubber band in the gusts that accompany gales. There is some worry on the parts of experienced skippers that too much stretch induces a “bounce back” that may give the the boat more distance to gather momentum in the next gust. I have watched for this and have not felt that to be the case. My snubbers last 3-4 years of moderate use and have never been retired for chafe. Nor have I noticed deterioration after a gale from being well stretched out. I use one rolling hitch (slightly modified) to attach and feel chain hooks have too many problematic elements to recommend them when a rolling hitch is so simple and checks all the boxes.

Michael Kornfeld

I have used my 55kg Spade for the last 3 years of cruising the island coastal and Great Barrier Reef areas of Qld Australia. It is our main anchor with 100m of 13mm chain, holding a 16m long, 30 ton sailing catamaran with flybridge and windage that “feels like the sail is up when it is down”. Most of the time anchored in sand. It dragged only once in the early days in shallows with a rode of 3:1. Since then preferring a rode of 5:1 (7:1 in large thunderstorms),I have never dragged even through 180 degree changes in wind or current. This is also true when I used 4:1. In 3 days of sustained 55 knot winds it did not budge. If there is any weekness in the spade (and probably most other anchors), it would be using a 3:1 rode in shallow waters. I have no affiliation with any manufacturer but experience with many different types of old and modern designs for over a decade and I can say the Spade has been spectacularly reliable and has a quick set. I have also had good experience with an Ultra and would appreciate hearing comments on an Australian anchor called the Sarca Excel, both of which are not mentioned. Without a doubt the problems I have personally whitnessed at various anchorages are almost always related to poor anchoring technique often with inadequate awareness of tides and chain length.

We too love the way our anchor drags

John said he likes my confessions so here goes another one, having happened this last weekend.
We anchored in the Schlei fjord in northern Germany Saturday night in our 45ft 1998 Jeanneau weighing about 12.5 tons/28,000 lb in a very shallow bay with mud and clay covered with lots of sea grass. A friend came to visit us with his older 52ft aluminum long-keeled ketch weighing very nearly twice that (24 tons/about 52,000 lb). The weather was sunny and warm and there was little wind so he came alongside and we rode to our anchor alone. We had a very nice evening and turned in before midnight.
Some time after one o’clock I woke to hard rain. In underwear I just put on a light jacket and went out to close anything that needed closing and to check on the anchor. Within minutes we were in the worst thunderstorm I remember. The wind was howling, the rain felt like needles and visibility was maybe 10 feet. I couldn’t see the mast from the bow where I was shining a flashlight on the bar-tight anchor chain, leading away at an awkward angle of about 45 degrees. As the raft of boats lay about 45 degrees to the wind, which I guess at 40 knots, they were listing heavily at maybe 15 degrees. Both our decks were level before the thunderstorm but because of the list, now 2 feet of my friend’s topsides showed above my deck, his fenders uselessly in the air, flapping in the wind (we had used fenders on both boats and my fenders were doing their job).
To anyone still believing in chain catenary, an experience like this will prove beyond doubt that you only have it when you don’t need it, not when you need it. My anchor chain had about as much catenary as a guitar string.
I ruled out asking my friend to cast off as this would have resulted in him running aground at best and colliding with another boat at worst and most likely wrapping a nearby fishing net around his propeller. The next morning we learned of another boat motoring around in the anchorage after getting the dragging anchor up, that ended up colliding head-on with someone else in zero visibility.
Maybe 20 minutes after it started, the thunderstorm had passed, leaving no wind at all. As if in irony, the chain pointed straight down.
So my S160 35kg/77 lb Spade saved the day. Two drinking glasses broke below decks on our boat and a french press coffee maker on our friend’s boat and that was the total damage.
As best as I can tell, we dragged about 20 or 30 feet. Alain Poiraud’s invention and my following Steve Dashew’s advice, that any anchor not ridiculously oversized is probably too small, saved my friend and me from serious expense that, in all likelyhood, an insurance wouldn’t have covered. We would have drifted down to a shallow area, collecting a fishing net mid-way and coming to rest in clay and mud at a 20 degree list in a non-tidal water with our boats interlocked. I think that would have qualified as a full-blown salvage operation with some goodies thrown in like cleats ripped out of the deck.
I learned today that Poiraud passed away in 2011. That’s sad news and I guess I would have hand-written a thank-you letter today instead of this comment otherwise. I hope he could look down on us that night and see his invention perform magnificently.
