Hi all,
I am in the planning stages of building and designing an aluminum boat. I am planning on using an electric drive of some sort. According to my math it should weigh about 800 lbs with no load or propulsion system. This is an offshore boat w/ a small cabin. My goal for the propulsion system is speed. I am a novice but here is what I plan on using: 7.5HP 3phase AC motor, 7.5HP VFD (Speed control,forward, reverse), a 6.3 KW peak diesel generator to power it all(7.5HP*746W=5595) plus boat electronics, drive shaft and 14" prop, and rudder of sorts.($1800 for all-new and used) I was not thinking of using any gears and going straight from motor to drive shaft. I know about hull speed *theory* and this boat will not plane as it is deep draft for stability BUT think cat/trimaran slicing thru water. (Low wetted surface area and great prismatic coef)
Is this feasible? Or are there other ways of doing this easier, DC maybe (golf cart motor)? Generator-pass thru battery charger-DC motor.
Thanks so much for any help or new designs you all can help me with!
