  • Great iPhone Mount

    Great iPhone Mount

    While I firmly believe that navigating on a phone is a very bad idea, and I’m no fan of installing navigation devices of any type on the steering pedestal (distraction), I have run into a situation where having my iPhone close to hand while steering is desirable: When anchoring I need to activate the Vesper […]

  • Fitting Jib In-Haulers

    Fitting Jib In-Haulers

    The in-haulers in action. A couple of weeks back I wrote about how jib in-haulers have pretty much removed the need to carry overlapping genoas on a J/109, like our Morgan’s Cloud. Several members expressed interest in learning more, so here are a few photos and some notes on how I set up our system. […]

  • A Nasty Danger of Twin Rudders

    A Nasty Danger of Twin Rudders

    As most of our regular readers know, we at AAC are not fans of twin rudders for a whole bunch of reasons, including complexity, vulnerability to damage and because they can’t be used in conjunction with prop wash to manoeuvre a boat, thereby making a bow thruster pretty much required for safe docking. But now […]

  • Don’t Be Fooled By A Coolant Overflow Tank

    Don’t Be Fooled By A Coolant Overflow Tank

    Our Yanmar, like most marine diesels, has a coolant overflow tank (left top). When checking the fluids, as I do regularly, it’s tempting to just glance at the tank and assume that if we see coolant above the “LOW” line all is well. But that’s not necessarily so: A friend of mine was in the […]

  • Networked Smoke Detectors Improve Liferaft Storage

    Networked Smoke Detectors Improve Liferaft Storage

    While we don’t plan to go far offshore in our J/109, we did buy a liferaft as our emergency exit if we are suddenly faced with a fire or a leak that we are not able to stop. We are often not carrying a dinghy, and even when we are it’s stowed deflated below, so […]

  • The Importance Of Boat Speed To Autopilot Operation

    The Importance Of Boat Speed To Autopilot Operation

    Modern smart autopilots rely on an accurate true wind calculation to steer well with the wind aft of the beam, particularly when a spinnaker, A-Sail or code is set. And assuming we have the apparent wind direction wand accurately adjusted for angle on each tack, another important input to true wind direction is boat speed, […]

    WakeSpeed Pro Alternator Regulator Announced

    Wakespeed have announced a new alternator regulator, the WS 500 Pro. Here’s the scoop based on an in depth email conversation I have had with Al Thomason, chief designer at Wakespeed.

  • Fun We Can Have Sailing Under Bare Poles

    Fun We Can Have Sailing Under Bare Poles

    I was out sailing singlehanded a couple of days ago. When I got back into our cove I, as usual when I’m planning to return to our wharf, dropped and furled the mainsail after starting the engine. But then it struck me that it might be fun to see if I could get alongside without […]

  • Q&A—How To Increase The Insured Value of Our Boat

    Q&A—How To Increase The Insured Value of Our Boat

    Question …The alternative was a policy only for boats with a value above $75K US. I have massively upgraded my 45 year old Morgan 382 for offshore voyaging (most recently a new Beta 35), as well as its cosmetics. But I know the market and no surveyor could honestly value it at $75K (my paint […]

  • Q&A—Sizing a Staysail Roller Furler

    Q&A—Sizing a Staysail Roller Furler

    Question Having a good look at some of the pictures where I can see the furling gear you used on MC it appears to me that it is about 1 size smaller then your head furler. Is this correct? And if so, were you ever concerned about its size in heavy weather? Member, Pepijn Answer […]

  • Interesting Refrigeration Option

    Interesting Refrigeration Option

    I have long been a fan of holding-plate refrigeration systems over evaporator systems: More efficient. When done right, better temperature consistency. Can be force-run when there is ample power, say when motoring or a generator is running—can be automated. Can be shut down overnight for quiet without the box thawing out or getting too warm—if […]

  • Don’t Buy Generation One Electronics

    Don’t Buy Generation One Electronics

    I’m not sure how many times over the years I have beaten some variation of this drum here at AAC. Here and here come to mind, but I’m sure I have written it, or something like it, many more times. And yet, when a new cool piece of gear comes out, what do we all […]

  • Reduce Spinnaker Snag Risk

    Reduce Spinnaker Snag Risk

    One of the nastiest spinnaker SNAFUs is when the sail jams in the V between the intermediate shrouds (D2s) and the uppers (V2s) at the lower spreaders (S1), usually on take down.

  • ARCO Zeus Ground Loop Problem

    ARCO Zeus Ground Loop Problem

    I recently received a link to this forum thread on lithium batteries that includes a concerning quote: Another note, during installation, there is a yellow and black wire on the Zeus alternator harness, “ALT GND” which is for a ground of the Zeus to the Alternator. In some installations, this has caused a ground loop, […]

  • Learning From A COB Tragedy

    Learning From A COB Tragedy

    I have just finished reading the above report from the Transportation Safety Board of Canada about the death of a crew member on the St John’s, Newfoundland pilot boat who fell overboard just two miles outside the harbour during a pilot transfer. At first glance we yachties might think that the lessons learned from this […]

  • Solar: Lead-Acid Battery Saver, Potential Lithium Wrecker

    Solar: Lead-Acid Battery Saver, Potential Lithium Wrecker

    The above is a graph of battery voltage on our J/109, currently still out of the water but uncovered. As you can see, each day shortly after dawn our solar panel starts charging and since, other than the first day when I was aboard and using power, there are no significant loads and the batteries […]

  • Boatyard Fall Prevention

    Boatyard Fall Prevention

    Us offshore sailors think and talk a lot about crew overboard prevention, but there’s another risk we subject ourselves to frequently that does not get much air time (ouch, bad pun): Falling off the boat when she is out of the water. And, believe me, even a 6-foot fall onto a hard surface can do […]

    Summary Table of Contents

    AAC, like most every WordPress-based web site, lists articles under Topics (or Chapters under Books) with title, image, author, number of comments, date and descriptive excerpt. And that’s great if you are exploring an Online Book to decide which chapters you want to read. But if you just want to get a sense for what’s […]

  • Elliptical Hole Hack

    Elliptical Hole Hack

    I have to cut an elliptical hole in the stern of our boat to accommodate the heater exhaust fitting above. And just to add to the fun and games, I need to also make two high-temperature gaskets out of silicon sheet. So how the heck do I get a nice clean hole just the right […]

    Don’t Fill Lead-Acid Battery Space With Lithium

    In this Tip I’m building on the last Tip in which I concluded that huge battery capacity makes little sense for most usage profiles. It’s tempting when replacing a lead-acid bank with lithium to simply default to installing all the lithium capacity that will fit where the lead-acid batteries were. And indeed that might make […]

  • Huge Battery Banks Generally Make No Sense

    Huge Battery Banks Generally Make No Sense

    I’m working on the second part of the Adventure 40 electrical system specification. One of the fun things about this project is that since we are starting with a blank page, rather than upgrading an existing boat, which I often write about, design fundamentals become more apparent. Here’s one that just came to mind:

    Great Headlamp

    I’m a huge believer in always having good light when working on our boat, so I wear a headlamp pretty much from the time I start a job below to when I knock off. And not one of those wimpy little things with a couple of AAA cells in them for me, I want a […]
