Exactly the reality check I need. Thanks for the time you spent on this!

Thanks OldEngr63, LiFePO4 battery banks, with gen-sets. The hull speed on these trawlers is 7-8 knots, thus the lower hp diesels. The research I've seen utilizes the torque of the electrics as an advantage by increasing prop size. The result is a lower kW requirement as compared to direct...

Steam King, Yes, LiFePO4 battery banks, with diesel gen-sets. I'm looking at older (but proven and well designed) hulls, so engines will need to be torn own anyway. With the savings on the older hull, I'll have $60,000 to $80,000 for renovations. It sounds like I would need to have multiple...

Hello all, I have limited education in physics and engineering, but I'm a tinkerer and plan on several projects in the next few years. I was looking for a place to shoot down my flawed ideas, when I came across your forum. I'm looking forward to discussions, and hope you will forgive any...

New to the forum, and can't find this info or examples on the web. I'm interested in the possibility of coupling multiple DC brushless motors to a single drive shaft for main propulsion on a 45-50', twin screw boat. Lots of sail boat examples are given, but my interest is in a power...
