  • Ocean Signal MOB2 AIS Crew Overboard Beacon Review

    Ocean Signal MOB2 AIS Crew Overboard Beacon Review

    Phyllis and I have long been fans, and early adopters of, AIS/DSC crew overboard (COB) beacons and we both wear one at all times when sailing, even inshore and in benign conditions. We also completely changed our person overboard recovery strategy to rely on the AIS beacons—definitely all-in on this technology. And, further, the several […]

  • Sails—Cross-Cut or Radial?

    Sails—Cross-Cut or Radial?

    This bi-radial genoa is old, but even so the shape is still pretty decent with a nice entry and good run off the leach. It would probably be even better if it was full tri-radial. A question from a reader made me realize that we have some gaps in our sail recommendations that will be […]

  • Wakespeed WS500 Pro, Shipping

    Wakespeed WS500 Pro, Shipping

    Al Thomason, co-founder and the designer behind our favourite alternator regulator, the Wakespeed WS500, gave me a call to say that the Pro model is now shipping to dealers and distributors and that the price is US$50 more than the original WS500, so around US$650. The harness, which will continue to be sold as an […]

  • There Is No Substitute For A 406 Mhz EPIRB

    There Is No Substitute For A 406 Mhz EPIRB

    Phyllis running a self-test on the EPIRB on our McCurdy and Rhodes 56 prior to a passage to Bermuda. We had the EPIRB in a float-free mount attached to the radar stand immediately above the liferaft. I’m increasingly hearing of cruisers going offshore with a satellite device as a substitute for an EPIRB: Garmin Inreach […]

    Q&A Inspecting an Aluminum Boat Hull

    Question Member Michael Asks: …I am looking for a used aluminum yacht…I have read all your articles on how to care for an aluminum yacht. However, how to look for serious problems on a used (25 years old) aluminum yacht? I know that I can check the electrical installation with a meter, but can I […]

  • Lock Stitch Brummel Splices

    Lock Stitch Brummel Splices

    I have now been doing and using bury splices in 12-strand Dyneema long enough to have come to the conclusion that these splices should aways be lock stitched, regardless of whether or not they were made with a Brummel lock. Without lock stitching it’s just too easy for something to snag the splice near the […]

  • Great New Book From Lin Pardey

    Great New Book From Lin Pardey

    Lin very kindly sent us a pre-release copy of her new book Passages: Cape Horn and Beyond (available October 15th). I have long been a fan of Lin’s writing but this is my favourite yet, I inhaled it. And that’s coming from a guy who does not read (or watch) a single cruising account from […]

    Near-Useless Radar Reflectors

    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

    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

    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 […]
