It's pretty crazy that the article does not state how many theoretical watts the yacht has. It looks like maybe 4,000 watts from the photo of the panels.

I wonder how much battery storage it has. Would suck to only be able to use the sauna when the sun is shining at full blast anyway.

  good thing about boats is that they can move a lot of heavy batteries relatively easily
  - eptcyka 11mo ago
    The boat is marketed as being lightweight.

      Relative statement. It may even require ballast, which the batteries can pull double-duty for.

    Water + batteries, lol. What could go wrong?

The guy who made it says it has a 6kW motor, but does not reveal details about his battery or PV array. Based on that number and the brief view of the motor, I'm guessing he bought this: https://www.epropulsion.com/products/electric-outboards/navy-evo https://www.epropulsion.com/products/electric-outboards/navy...

The video that the person made has the stats. (see further up, its only about 8 minutes) From memory its a 5.4kw array with 8kw motor. At 400w it can (on a calm inland sea) cruise at around 3 knots. Top speed of ~9 knots. Its made from plywood so its super light. he wants to take it across the atlantic, which I think is brave given that its not got any compartments(that I could see in the video), so any breech means it'll sink in minutes.

  Brave or stupid ? What I could get is that he is a young fool looking for "freedom" where there is none to be found. The boat isn't even interesting anyway, it's a bit dumb to spend that much money on an inadequate power solution when a cheap refurbished ICE would have been just fine.

    > cheap refurbished ICE would have been just fine. I mean an outboard would do, but then you are limited by range, also its noisy as hell. Sure you _could_ install an inboard second hand cummings with 10k hours. but thats not cheap or easy. So you're left with outboard motors. They are cheap and don't vibrate the entire boat, but they are still noisy. Plus they aren't actually that much cheaper to buy than electric. but then there is the running cost, it'll be (at uk prices) about £3.50 an hour to run on diesel, vs £0 on solar. Plus all the extra space for not having to install fuel tanks. my issue is more that the hull is untested and doesn't look all that strong.

      Sure, if you plan on running the boat as a way to make money the total running cost would make sense, but it's just a leisure boat so the financial aspect isn't really good to start with. It's just a way to have fun while burning money. But yes the bigger problem is the hull, that clearly isn't ready for difficult situations and this is why I said that. If you just want to have fun it's not really worth it to spend all that money for mediocre capacity when you could have gotten a decent experience for much less. I really don't get it, a sail boat makes much more sense if you just want to have fun without relying too much on a noisy motor.
