Why not? Seems perfectly logical to me with lithium batteries. It's probably a bigger adujustment for them than cars though, because they're used to having a couple tanks full of dino fuel. I used to hang out with guys with 21-26ft speed boats (big and small block Chevy race engines). We could stay out there pretty much all day, and the boat just got faster as the fuel load lightened. We'd just ride around the lakes, burning off excess fuel, looking for a race....didnt think an Eboat could be done...
The man's got a point...Never understood the need for bikini's. Would JRP3's picture really be missing something?
Do a small personal watercraft with some LiPo, just for the fun of it!I've been itching to do a boat but traveling above displacement speed takes a lot of energy, there is no coasting in a boat, so range is going to be severely limited even with a sizable pack. I don't think I could live with displacement speed only.
Been thinking about that too, I have a SeaDooHX, but I'm not sure I could pack enough batteries in it to get more than 10 minutes of full throttle, and I'd need a sealed water cooled motor. It would be an expensive project with limited use at this point.Do a small personal watercraft with some LiPo, just for the fun of it!
Basically. Below displacement speed boats take little energy to move, once you try to go above displacement resistance goes way up until you get over the bow wave and get up on plane, if it's a planning hull. Then you can keep it on plane with less energy but still more than sub displacement. A lighter flatter bottomed boat would be easier, similar to what gottdi posted. I've got a 23ft. deep V with a 454, not the best project boat.I'm guessing "above displacement speed" is what I called "getting on plane"?
What about an air-cooled motor in a sealed compartment, with a shaft protruding through to the prop? Could possibly even do a water-to-air cooler for the air, since there's a never-ending supply of cool water. Of course, I'm going off into my high-budget, sky's the limit, ideas again huh....and I'd need a sealed water cooled motor...
