[Electric Boats] Re: New To the forum and thinking of Repowering a 65 motor sailer

 

Rob, the part of the message that dealt with contacting the broker was not directed to you,Sorry if the post came off in that fashion. just to a unknown party.

It dosent seem over complex, just good redundancy, I have two steering stations, 3 autopilots, 3 anchors, ect... I believe in redundancy, It seem simple in my mind. First they dont make a large enough motor for my application, and as the size increases so does it limit choices. The price more than doubles per horse power, and the battery charging and controllers are limited, Needless to say not every were I can get 220v or 440V for shore power. If I ran multiple battery banks of 24 or 48 volts, I could be generating enough power with the gen set alone, until I engage most or all of the motors, and then it would only drain them down past the gen set power contribution. I went over to the DIY Cars and they are doing similar projects, but they are limited in room and weight, I have much more room than a pinto, and can handel much more weight than the current ICE.

Now in the car forums they half the load at start up and then half the voltage and double the amperage once the vehicle is moving a certain speed, this I believe is so that they dont over heat and blow the motors from the torque, Or did I miss something? Will I have the same problem? will cooling satisfy this effect?

Thanks again for the responce

Nicholas
