Read more: Elliptical Hole HackI 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 […]

Read more: Don’t Fill Lead-Acid Battery Space With LithiumIn 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 […]

Read more: Huge Battery Banks Generally Make No SenseI’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:

Read more: Great HeadlampI’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 […]

Read more: Beware of Ocean Options, Tiverton, Rhode IslandWe just got ripped off. Here’s the story in the hopes that it will save someone else from the same fate. Some 25 years ago we bought a D8 Espar heater from Mike Bowden owner of Ocean Options of Tiverton, Rhode Island. And over the years that we owned the McCurdy and Rhodes 56, Eddie, […]

Read more: Block Stand-Up HackOur 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 […]

Read more: Great Source For Epoxy Use TipsWhile 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.

Read more: WakeSpeed And Victron Get Even More CuddlyI’m on the Beta test list for software Upgrades to the WakeSpeed WS 500 alternator regulator.

Read more: Cover The Negative Terminal On BatteriesOne 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 […]

Read more: Another Danger With MRBF FusesThe 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 […]
