Re: [Electric Boats] ~40' Electric catamaran

 

> www.enstrol.si The EMRAX motor is 11.7 kg and can be used continually up to 40KW,

Wow, very nice motor. Are downsides to this type of motor vs the
Kostov 11" I mentioned? These seem better in every way (MUCH lighter,
lower RPM, liquid cooling). What do they cost?

> I am using 144 volt 160AH life batteries and expect 25KW per engine continuous, (water cooled) backed up with a 20hp al water cooled diesel weighing 55kg (gearbox also) two units one in each hull.

How are you tying the diesel engine into the drivetrain or are you
using it as a generator?

> Hope this is of help to you I have been designing and chasing parts for two years as the work proceeds.

Helps a lot, thank you!
