Re: Optimal propulsion system
Well how these systems are put together by engineers is not a full hp generator but one much smaller that runs at best efficiency most of the time. If you need peak power you need to drain batteries.The electric motor is left freewheeling and becomes a generator while sailing to refill batteries.Genset would come on at preset drain point on batteries or by manual start.
The genset etc don't go in the bow.That effect trim to much.
There are several systems in place right now and some Charter cats have/are being produced. Look at there set up for ideas.
We all do different things in life to earn money. Go do that and leave system design to Electromechanical Enginneers.
3 phase ac motors? VSD's? varispeed gensets? There is so much wrong here I won't even comment but if you PM me I will recommend a few books if your interested in the subject in some real way.
