Escapeartist.... There are lots of people already doing exactly what you're interested in. Search for the yahoo group electric boats. Lots of...
And sun21, the first solar transatlantic boat. About 42' I think. Also the solarwave 46 which was the predecessor to the solarwave production...
I'm also interested in this idea. You know. Everyone says it'll be too slow....it won't work....don't waste your time. But. Just google solar...
Ok, So I've found a torque graph for the M92B showing it's torque curve. Not a great graph but it's all I can find....
Hi Again, I was gearing down to an output rpm of 800, not 1200. Not sure that makes much difference though as it would apply to both. Thanks...
Hi David, I used this motor for the comparison:...
Hi Barry, I just used the specs from the manufacturers website....
Yes. Agreed. 10pc might be high. But it's the same deduction for both. The point I'm trying to clarify is...it looks like I could swing a larger...
I've been digging around on this subject for months and my understanding is, it's torque that turns propellers. Who cares what the horsepower...
LOL....what size, now that is the question. I want to build a (predominantly) solar powered displacement cat. It would be nice to have a cruise...
Please would you guys help me out here. Sail powered catamarans tend to have a length to beam ratio somewhere around 2:1 Power catamarans tend to...
Hi Gonzo, At the moment talking about peak production. Wondering where peak production is likely to be in ten years time. Realise the max...
Like many people, I'm interested, and having a good look at powering a boat with solar panels. Current efficiencies are sitting at about 20-22%...
