  • Block Stand-Up Hack

    Block Stand-Up Hack

    Our J/109, in common with most boats with spinnakers, has turning blocks for the sheets that must reorient to loads from different directions, depending on the point of sail, and therefore uses loose blocks on pad eyes. The problem with this is that spinnaker sheet blocks tend to bang on the deck with motion, in […]

    Great Source For Epoxy Use Tips

    While researching for a discussion we were having about epoxy shrinkage (or not), I came across a great site with a ton of information and tips on using epoxy resin to make repairs. I particularly liked their myth-busting post. Despite having used epoxy for over 40 years, including for a refit that turned into a […]

  • RIP Good Old Boat Magazine

    RIP Good Old Boat Magazine

    I have been a subscriber to Good Old Boat magazine ever since I had lunch with Mike, the then editor, while attending the 2019 Annapolis Sailboat Show. I signed up first because I liked Mike and felt that he was a genuine guy who had done real cruising and really wanted to help get other […]

  • WakeSpeed And Victron Get Even More Cuddly

    WakeSpeed And Victron Get Even More Cuddly

    I’m on the Beta test list for software Upgrades to the WakeSpeed WS 500 alternator regulator. Not because I like testing new software—only marginally more fun than having a root canal, in my view—but because I’m a huge fan of the regulator and firmly believe it’s currently by far the best option for charging most […]

  • Cover The Negative Terminal On Batteries

    Cover The Negative Terminal On Batteries

    One of the things I love about my job is that, despite having maintained and refitted boats for over 50 years, I’m still learning, often as the result of the discussions we have in the comments. This has certainly been the case here as I think about reducing short-out risk on batteries, particularly lithium. One […]

  • Another Danger With MRBF Fuses

    Another Danger With MRBF Fuses

    The great discussion on my recent article about proper battery fusing and particularly the potential danger of MRBF fuses failing closed, instead of opening the circuit in the event of a short circuit, reminded me about another big downside of these kinds of fuses that actually negates the supposed advantage of being able to install […]

  • Insurance Claim Denied

    Insurance Claim Denied

    It’s possible that our insurance companies will deny a claim if anything on the boat is found to be not compliant with with the terms of the policy, even if the defect in question had nothing to do with the loss.

    Under-Torquing Is Dangerous, Too

    Here’s something that I only recently really wrapped my aging brain around: the danger of under torquing fastenings, other than the obvious one of them coming loose.

    Gales at Anchor Are Not That Scary

    I don’t watch a lot of videos, in fact hardly any, but I was searching for something else when I stumbled on this video over at S/V Delos. Now, there is no question that hurricanes are scary. You don’t have to tell a guy from Bermuda, who cruised the western North Atlantic for over 50 […]

  • We Can Never Have Too Many Gloves

    We Can Never Have Too Many Gloves

    I have been doing a bunch of work on our J/109 with epoxy resin lately. Nothing structural, just mounting some hardware, and improving the mounting for a couple of turning blocks. Stuff that requires replacing core and bonding backer plates. This kind of work involves handling things covered in epoxy and then handling tools…and then […]

    Source For Custom Jacklines

    We have long advocated for jacklines made of heavy Dacron webbing, but in recent years it has been difficult to source them already made up. But now there is a new vendor offering custom jacklines. One suggestion, I would not use their Jackline Assembly, consisting of a shackle and cover. The problem with this approach, […]

    How To Blow Up Your Alternator

    Anytime I write about batteries and charging someone is bound to bring up one of the clever gadgets that fool a stock alternator into charging at a higher current for longer without resorting to external regulation. Some of these gadgets, particularly the VRC-200 from Nordkyn Electronics, are undoubtedly very clever—here’s another one I wrote about. […]

    Member Charlie R suggested in a comment to a Tip about the new AAC site design I’m working on that it incorporate dark mode.
