This summer Chrysadev, makers of the eWincher, were kind enough to send us a unit and two batteries for evaluation.
And, as it happens, events conspired to make this an even better test than it might have been in that I managed to screw up my neck while removing a recalcitrant hose from a defective pump. While the injury is getting better slowly—everything gets better slowly at this age—it has meant that lots of high load winching is out.
OK, with all that pissing and moaning out of the way, let’s take an in-depth look at eWincher. And when I write “in-depth” I kid you not, this in three parts.
I know, seems like a lot of blather about a winch handle, but bear with me, this is a revolutionary product.
And it’s also an expensive product, so I owe you a detailed look to help you decide if eWincher is for you—an impulse purchase, this is not.
Thanks for the detailed review. I bought an ewincher last winter and used it this season. I solo sail a Blue Jacket 40 equipped with an electric main halyard winch. The primaries were prewired at the factory for conversion. No way would spend that kind of money to convert. ( I imagine this will be covered in part two) This devise is brilliant. I use it to trim the mainsheet when closehauled. I use it to get a fast and easy furl on the big Solent rigged reacher. I like that I can pay attention to sail shape as I make small adjustments to sail trim. When winching manually I tend to assume an head down stance over the winch. Yes, the ewincher takes practice and with all electric winches, one has to be cognizant so not to break stuff with your new Superman strength. One last thing. My unit was delivered with a faulty charger. The support was nothing less than spectacular. Through a series of quick response emails a diagnosis was made and new charger was sent within days. I give ewincher 5 stars. At age 66, I still enjoy the physicality of sailing and manually winch the majority of the time. However, ewincher is a great first mate, especially in a fresh breeze when the loads increase and speedy action is required to reduce the chance of cockpit mishaps. It ain’t cheap…quality kit is expensive. Ewincher is worth every penny.
Hi Karl,
Thanks for the real world report. These are worth more than all the reviews in the world.
Also very good point on how eWincher compensates for strength differences between two people. I will put that in Part2.
Interesting.
I’m interested in, but haven’t tried, Karver Pontos 4 speeds. Have you?
Hi Robert,
I have not, that said, after thinking about them briefly for our boat, I moved on. The key point is that as boats get bigger, or we get older, or both, the big problem is not load on the handle, it’s endurance. So if you have very high ratios on the winch it’s just going to take a hell of a long winch cycle to get anything done. The problem is not solved, it’s just lengthened, whereas eWincher solves the problem by both reducing the effort and the duration.
The proof of this is how much easier eWincher made the low load, but long duration tasks on our boat like furling the jib top and grinding in the mainsheet prior to a jibe, as I detail above.
I guess the power draw is higher on the eWincher than on an electric winch. They are doing the same work but with an extra mechanical power transfer and an extra inverter/charger/battery stage for the eWincher. At best they are comparable but the electric winch must be more efficient. Or am I missing something?
Hi Björn,
I guess I could see that in theory, but it does not work that way in practice. We found we still hand winch the easy stuff and there is also assist mode so both are big savings over a fully electric winch boat. I also eWincher will use way less current when in a low load situation (most of the time), whereas an electric winch has a big electric motor that takes a bunch of current regardless of load.
There is also a tendency with electric winches to use the electric function for the entire sheet retreaval, whereas with ewincher we tend to pull the slack in while free spinning the winch.
There are probably other issues, but the bottom line is that our current usage over the summer was immeasurably small, whereas I was advised by Lewmar when I looked at electric winches that I would probably need to upgrade my batteries and should consider changing to 24 volts.
To back this up, I just checked the Lewmar manual and they are recommending 1/0 AWG cable. Gotta tell us something!
And the manual also shows that even a Number 40 (small winch) has a 3.5 amp draw at zero load that goes to 140 amps at 500 kg. Lets say 80 amps at 12 volts for 1 minute for a typical task. That’s 1.33 amp hours at 12 volts. So do that 6 times and you have used as much electricity as we did on Morgan’s Cloud in three days of sailing. And that’s with a small winch. The number 65 like the ones we have on MC take 6 amps at zero load going up to an eye popping 350 amps at 1580 kg.
So, assuming an averge load of say 200 amps for one minute would be 3.33 amp hours at 12 volts, so just four tacks (assuming 30 seconds use on each) on our boat with electric winches would use as much electricity as three days of sailing with eWincher.
In summary, real world use on MC indicates that the eWincher uses about 5-10% of the electricity of electric winches, maybe less.
Of course the eWincher will draw less of you use it less. An electric winch has high power draw because it does a lot of grinding work. If you do the same amount of grinding work with the eWincher, it will draw even more. Unless the electric winch makes heat of most of the power but then it will probably burn.
Hi Björn,
Maybe, but who cares, the point is that in actual use on a big boat eWincher uses very little power.
Also, as I said earlier, electric winches use way more at low loads because of their large motors sized to bring in a lot of rope quickly at high loads. Take a look at the consumption graphs in the Lewmar manual and you will see what I mean.
But the high numbers are just momentary inrush current. A Harken 72 is just 1500 W. You need to size the cabling for the peak but that has minor effect on the average draw. And, even at low speed an electric winch is pretty fast. You cannot use a minute at 200 Amps for a tack! I would rather say 20 Amps for 10 seconds.
Björn,
Sure that’s one way to look at, although based on the warnings I got from Lewmar, I’m guessing your numbers are way low. But then again, my numbers may be way high. There may also be factors at work that neither of us have thought of. For example, the little motor in the eWincher might be a lot more efficient than the one in electric winches.
Also I did not say a minute, I wrote:
Bottom line, we could argue this for days, but why would we? None of this matters against the fact that our battery usage recharging eWincher after sailing a big boat for three day sails was less than 8 amp/hours—so low as to be inconsequential, which is the point that matters to those considering whether or not to buy one.
I love it that we’re talking about volts and amps.. LOL. $3000 USD+ to save a few seconds and a few calories per tack. I can think of a few things… actually, my entire list of things to do, at any priority, would come before getting one of these.
Hi Kevin,
I suspect you are not 69 with a bad back and an injured neck. No one is suggesting that everyone needs one. In part 2 I have written about when buying an eWincher makes sense, and when it doesn’t.
Hey Kevin… lets see if after 30+ years of cruising .. with your partner/wife also turning the winch handle under high loads … if you think the same way. Bottom line: people do what they can manage. In my experience, after 31 years of cruising, to keep the experience enjoyable/comfortable/safe one needs to ‘futureproof’ more and more… just food for thought.
That said, good on you for being capable of being out there and managing your ‘list’….
Hi John,
I bought one three years ago. I have sailed something like 20 000 NM with it on my 15T Garcia sloop. With my wife or singlehanded. I don’t imagine to sail without it anymore. From my experience I concurr with all you said, with all the figures you gave. One more figure : to hoist me (75 kg) at the top of the mast (16 m) only represents 15% of the battery capacity.
Yes, it is not cheap but just let us imagine that for the same service we want to convert four or five winches to electric ones !
One more point : after 18 month of use, Chrysadev offers me to service the handle for free. Everything was checked, the software updated and improved (I bought one of the very first one) and the square end cap changed to better suit the drive shaft of my Andersen winches. Top quality after sale service.
I don’t regret my investment at all !
Hi Eric,
Great to hear, particularly since I just bought the evaluation unit from them! Thanks
High John,
Please correct me if I am wrong. The e-wincher will not have the same tendency to break gear as an electric winch, because the operator actually has the load in their hands. Therefore you still feel the handle load.
Hi Ray,
I will be covering that in part 2…preview: you are right.
Power Arm is yet another model, Australian made, for $AU1600 (~$US1150). It appears to run on 18V Milwaukee batteries, so most of us would not need to buy extra batteries or charger. Only recently advertised. I have seen no reviews, and do not know of it’s functionality or quality. But reasonably priced.
Hi Peter,
That’s certainly a clever approach. One thing I wondered about immediately is how water resistant it is. I would guess that one splash of salt water down the slot between the battery and the rest of the assembly is going to be a problem, but maybe they have figured a way around that.
One of the slide pics shows the Powerarm with some sort of neoprene looking cover that looks designed to protect from light impacts and splashes. Clearly it’s not meant to go swimming, but in the cockpit of a larger vessel it should be possible to keep it safe.
Overall it’s not as smart as the E-Wincher, but I can afford one 🙂
I got a 200nm sail on a big Swan with electric winches last weekend and I’m convinced on the merits of power assist. (The owner of this boat is a professional skipper with an outstanding racing record and he’s no snob about going electric.)
Hi Philip.
I guess I’m just not convinced about any electrical piece of equipment that is intended to be used on deck that’s not waterproof. In my experience, even with a good dodger, the cockpit of a boat offshore is a pretty damp place, so I’m guessing the life of powerarm is going to be short making it more expensive over time than the eWincher.
So, given that, I think that if I wanted a budget option I would go with WinchRite. More coming in part 2.
OK… Valiant 40…..we have an Andersen compact motor drive electric winch that drives the main halyard, reef lines, staysail halyard, spin halyard (all thru cam cleats under the dodger). The Genoa, mainsail and staysail sheets, roller furling lines are still 2 speed Andersen ‘grinders’ (all convertible to electrics)… as we get older (60 years now!!!), on passages with fickle winds, it gets laborious…. most polite way of saying it…..
As a prelude to this report we have tried the cheapest option of ‘electrifying’ the other winches by using a Ryobi 18volt electric contra-angle drill with a winch driver bit….. it works ….but not really all that well: heavier loads/winds and it simply is not enough ‘grunt’ for the task. The bit was only $25.00 NZD thru Foster’s here in NZ. The drill was less than $200.00 NZD and we already had it onboard. I’m convinced that this e-wincher modality it the way to go after reading this report…. we have read similar reports from other places and compared these (i.e. the ‘Winchrite’)… we just needed a report from someone we trust who actually had the sea trial info to confirm the E-wincher motor was up to to it… The Andersen compact motor was very expensive… about $6000.00 NZD at the time we bought it years ago… no way we would do that again for 6 more winches…. it seems a ‘no brainer’….
Thanks John for the excellent report. Really appreciate it. We’ll update the site once we get ours and get it trialed onboard in some winds… All the best…
Hi Deven,
Thanks for the kind words. Believe it or not, I have two more parts of the review in the hopper! That said, seems like you have already made a good decision.
My Lofrans power windlass allows manual operation using a winch handle. Fortunately, I’ve not had to use this feature in anger, but just a few minutes of testing it out leaves me dreading the day when I do.
An electric winch handle might be a good option for operating my power windlass manually in the event of a failure, rather than dragging the rode down the side deck using my electric primaries. I couldn’t justify the expense at the moment, but I thought I’d toss the idea out there as an interesting application for an electric winch handle, hopefully without instigating a side conversation about the pros and cons of electric windlasses. 🙂
Hi Edward, I have done so with a Lighthouse Windlass in practice with an EWincher and it does the job very nicely.
My best, Dick Stevenson, s/v Alchemy
