  • Near-Useless Radar Reflectors

    Near-Useless Radar Reflectors

    It amazes me how many of these tubular radar reflectors I still see on boats years after two credible studies have shown them to be pretty much useless: Login to continue reading (scroll down) Learn About Membership Get to know us for FREE Username Password Remember Me     Forgot Password

  • We Have An Adventure 40 Builder

    We Have An Adventure 40 Builder

    Great news, an experienced boatyard with great technical skills has committed to building the Adventure 40 and is already working with Maxime on planning the next steps, including reviewing the design with a view to both making improvements and optimizing for build efficiency. The builder agreed to have their identity revealed now, a further indicator […]

  • An Interesting Alternative To Lithium Batteries

    An Interesting Alternative To Lithium Batteries

    We are all aware that in yacht use the Achilles Heel of lead-acid batteries is that only about 50%1 of the rated capacity can be used on a daily basis. But now Trojan, a well-respected brand, have released their AES AGM Battery with a claimed life of 1200 cycles to 100% discharge. These batteries are […]

  • Preventer Video

    Preventer Video

    We just published the first of a two-part article on building a safe boom preventer, and, by coincidence, John Kretschmer also published a video showing his preventer in action, including what happens when caught aback. John designed and specified his preventer using the work done by Kurt Zinsmeyer, the author of the AAC article. Well worth […]

  • Adventure 40 August Non-Report

    Adventure 40 August Non-Report

    Several members have expressed concern that we have not published anything about the Adventure 40 since April. But this is a case where no news is not bad news, it’s simply no news. While it’s true that, for a variety of reasons, all outside Maxime’s control, not a lot has happened over the summer, he […]

  • Wakespeed WS500 Pro On Test

    Wakespeed WS500 Pro On Test

    Well, that was quick. It was just last week that I shared that the WS500 Pro was on time, and today what should turn up here at AAC World Headquarters, but a fully functioning production unit. Al put on his red suit and slipped down the chimney to put it under the tree…wait, that’s not […]

  • Wakespeed WS500 Pro On Time

    Wakespeed WS500 Pro On Time

    In April I hinted about a Bluetooth-enabled version of the WS500, our favourite alternator regulator, and in late June I confirmed that the WS 500 Pro had been announced, for shipment in “fall of 2024”. That said, I always worry that products announced before they are ready to ship will be late, often horribly. Anyway, […]

  • North Sails—Another Monopoly

    North Sails—Another Monopoly

    I’m a capitalist. But I also strongly believe that capitalism should be played with rules and a referee. After all, as Scott Galloway is wont to say, it’s a full-body contact sport and would we let people play rugby or American football without a ref on the field? Might not end well. But that’s exactly […]

  • The Correct Shore Power Charger Profile To Use For Lead-Acid Batteries

    The Correct Shore Power Charger Profile To Use For Lead-Acid Batteries

    As I have written before, most shore power chargers are far less smart than they claim to be. The problem is that unless chargers are connected to and compatible with monitoring systems like Victron Cerbo with Distributed Voltage and Current Control (DVCC) enabled, or Victron BMV with VE Smart Networking, they have no way to […]

  • 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, […]

  • 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

    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

    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 […]

    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

    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

    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, […]
