power

Hello all, I hope this thread is well placed here, if not, please let me know better one. I'm currently in the process of define the power requirement for a small catamaran (less than 5 m length), with an electric propulsion. Could someone share with me any information (formulae, estimation...

What would be the average energy consumption, range and running hours with different speeds (slow, cruising and max)? What would be a right size diesel generator for backup/hybrid system? How much regeneration could folding propellers produce? How much solar would need to be installed to run all...

Hi there A few years back I posted some design ideas for an 80 ft power trimaran on the forums here and received a lot of very good feedback from the members which I really appreciated. It helped me to refine what was important and to get read of a bunch of stuff that wasn't. As a result I went...
