    You may or may not be shoal-draft enough to have fun on Wolf Lake but Iliana Yacht Club is who you’d want to talk to about the practicalities of that.

    I hope this means superyachts carrying cannon.

    Diesel Engine Delete

    I run the numbers every once in a while to see how battery power stacks up. 12 HP (You may need more, but that would be enough for me)= 8950 watts give or take, let’s call it 9 kw 9 kw * 30 hrs = 270 kwh, let’s call it 300. currently (https://books.google.com/books/about/Lithium_Ion_Battery_Chemistries.html?id=2laXDwAAQBAJ) “Lithium ion batteries hit a wall at about 300 Wh/kg” so you’re looking at 1 metric ton or 2200 pounds of batteries for that get-home-from offshore capacity if your designer can design for ballast under your floorboards, a ton of batteries might work for you cost wise, current big Li-ions are in the neighborhood of $200/kWh, so that 300 kWh will run you $60,000. (ibid.) (The consensus for land transport is that halving that price per kWh is both the crossover point for where gasoline will lose for most applications. It’s also expected in the next ten years.) I’ll leave the reliability questions to the rest of you, but the “size of the tank” is calculable.

    I’m disappointed that he lost steam on it. 100% done and full throated goofy is like ten times better than 90% done goofy.

    Summer reading ideas

    Absolutely. Also his Voyaging Southward from the Straits of Magellan, reissued recently in paperback by Wesleyan University Press IIRC. It's in the next room over and I'm too softhearted to wake up the dog sleeping at my side to go check. And Kent's illustrations for Moby-Dick are pretty much perfect as well.

    Umm, how/why the hell did someone even do that to that boat? It's like (cartoon version of) an industrial laser accident!

    Malort is like a liqueur with a lovely floral and herbal bouquet, except that the flowers and herbs have rotted in the back of the fridge for six months. (I love* it.) *in a weird abusive love relationship.

    fishing boat tries to mate with J105

    TBH: better than expected. Not collision porn. No one hurt (kind of amazingly) means ideally a teaching moment. They (seamanship teachers! that's good!) made their points but probably could have hammered them home harder: KEEP A F$)^#NG WATCH. (and much quieter, don't expect the rules to protect you)

    Another Interesting Home Built Steel Boat

    A little surprised that there hasn't been any mention of Tom Sukanen, who (in the 1930s) started building a steamship on his own (with a plan to sail home to Finland) ... in the middle of Saskatchewan. There's an excellent novelization of his story: Dustship Glory by Andreas Schroeder. Ship still exists and can be seen here: https://www.sukanenshipmuseum.ca/tom-sukanen/

    Father of modern SAR

    Yeah, Michael Lewis knows how to build narrative effect to the occasional neglect of complicating factors (he's a storyteller, not a historian). Summary for @The Q and others paywalled out: Profile of Arthur Allen, who over the course of a career in the US Coast Guard did a ton of research on how things drift, then worked with a bunch of others (not profiled, see above on distractions from the narrative) to build a really usable software tool to help plan searches for drifting people and things. Plug in the last known location, select the type of object, and it will take wind and current information and give you a probable location to search in. He's also researched other practical things like survival probabilities, probabilities that a searching aircraft will have seen a given object in the water (whether you should cover an area again), etc.
