    Why We Need a Traveler

    We increasingly see boats without travellers, but that’s a big performance hit, particularly in light air going to windward where we want the boom on the centreline but the sheet not too tight. To make that happen the traveler car needs to be well to windward of centre. Check out the nice twist and leach […]

  • Demo of In-Boom Furling

    Demo of In-Boom Furling

    My friend Hans, who advised me while I was writing the article on the tragedy aboard Escape, took me out on his Farr 56 for a demo of hoisting, reefing, and furling, using his in-boom automated mainsail-handling system. Hans is an incredible resource, since he has owned boats with slab, in-mast, and in-boom furling, as […]

  • Safer Transom Ladder

    Our new-to-us J/109 has a robust transom swim ladder that could definitely enable someone who fell overboard get back into the boat, at least in smooth water. But check out the photo above: There’s no way for someone in the water, particularly wearing a lifejacket, to deploy the ladder unassisted. The angle is just wrong […]

  • Nylon Line In Europe 2

    Nylon Line In Europe 2

    The plot thickens. I came across this product page at RobLine an Austrian rope maker and they have a bunch of lines for mooring, docking, that will be good for anchor snubbers. Interesting quote from that page: Robline caters to the trend toward using different fibers for mooring and anchor lines, depending on the specific […]

    Starlink Maritime

    Starlink are going to provide a solution for moving vessels, but before we get too excited check out the price! Think US$10,000 for the unit and US$7000/month for service! Looks like I will be right that Iridium will the solution for most of us for some time to come. In 2019 I predicted 10 years […]

  • Nylon Rope in Europe

    A member was having a heck of a time finding Nylon rope for a snubber, as we recommend, in Europe. After some research I think I have found out why: What we call Nylon in North America, and the UK, is known as H.T. Polyester in Europe and staff in stores sometimes refer to it […]

  • Backstay Adjusters & Fractional Rigs

    Backstay Adjusters & Fractional Rigs

    With fractional rigs we are way more interested in how much pumping the adjuster down has shortened the backstay and bent the mast than we are the reading on the pressure gauge (within reason). That’s why the marked batten. Click on images to enlarge

  • Reaving Halyards

    Reaving Halyards

    You see people taping messenger lines to halyards, but that can lead to tears when the messenger comes off inside the mast. So way better to put a flemish eye, sometimes known as a reaving eye, in the bitter end of all halyards and internal reefing lines. The key to success is that the eye […]

  • Whip Before Cut

    Whip Before Cut

    When shortening a line, it’s way easier if we put on two sailmakers whippings and then cut the line between them. Whipping how-to. (Scroll down to #6)

    How Hard Can We Charge Our Lead-Acid Batteries?

  • Folding Props Not For Cruising

    I made a bollocks of sailing off the mooring today and got stuck stern upwind on the chain. Not a big deal to sort out on a light J/109, but I did get a graphic reminder of how little reverse thrust folding props have. Definitely not appropriate for a cruising boat where the bigtime reverse […]

  • Whipping not Dipping

    Whipping not Dipping

    This dock line came with our new-to us J/109. Not only does it have a loop spliced in one end, which I recommend against (#2), someone first whipped it and then dipped it in some goop for reasons I can’t fathom. There is no better way to prevent a line end unraveling than a sailmaker’s […]

  • Dean Barker is Back

    Nice to see that one of the best, and arguably most unlucky, sailors in America’s Cup modern history is back with a team. I’m a huge fan of the quiet Kiwi. The man is a class act. He will be a great coach, I’m sure. Might end up back on the wheel, too, I’m guessing.

    Selecting battery master switches and deciding how to wire them is a fundamental part of a good cruising live-aboard electrical system.

    Most “Drop In” Lithium Batteries Not ABYC Compliant

    The way I read this, batteries with BMSs that do not communicate are now obsolete: If a shutdown condition is approaching a battery system should notify the operator with a visual and/or audible alarm before disconnecting the battery from the DC system.

  • ABYC Publishes Lithium Battery Standard

    The TE-13 technical note is now a standard: E-13. To me, a woefully inadequate one that relies far too much on the vendors to do the right thing, but it’s a start. Panbo has a good analysis, most of which I agree with.

  • Great Borescope

    Great Borescope

    A borescope is how we knew what the problem was causing chafe of the main halyard in our mast way out of sight: Black and white messenger is for the main halyard. Deflection is clear. Tor of mast sheave to left. When buying, make sure you get one with a longer focal length.

  • Stupid Mast Errors

    Stupid Mast Errors

    After just three day sails our main halyard is mangled. Turns out @sparcraft jammed the wiring conduit right up under the sheave on our brand new mast so it deflects the halyard and chafes it. Looked like end of season. We were gutted. No way to fix without unstep, but see next tip.

    No Position

    We were out sailing our new-to-us J/109 when I realized that neither of the default screens on the plotter or TZiBoat showed position. Pretty standard these days…and oh so wrong. Imagine a crew overboard and we need to radio for help, but first have to dig through a bunch of screens to find our position. […]
