Re: [Electric Boats] Re: New Member

 

Welcome aboard Scott. Lot's of information here and in the files. Lot's of knowledge and experience from those of us who have made the leap to EP and never looked back too.
You should be able to get all your questions answered.

Hello to everyone at electricboats,
my name is Scott Uggla, I just became a member and just wanted to introduce myself.
I do not own a electric boat yet, but I love the technology and have set aside some money to either
buy a sail boat and do  a electric conversion or I may do something on a smaller scale
like a large canoe or small light sailboat, I am 58 years old and have some electric
golf car experience and was a mechanic (diesel and small engine) in my early years
I also have had some micro processor experience, and currently work in the low
voltage industry. I am currently reading The Propeller Handbook by Dave Gerr and
The Nature of Boats by Dave Gerr as  well. and wow I think I will be reading and re-reading 
these for a while.
So you will probably be hearing from me soon, more likely questions than answers, at least,
until I get a better understanding of some of the design concepts and a little experience
behind me, Thank you to the Moderator for Acceptance in to the group and all the helpful info.

RE: [Electric Boats] 5KW or 10 KW

 

Electric Yacht recommends 5 KW up to 7000 lbs and 10 KW up to 12,000. The larger motor  would not labor as much so should run cooler and be more efficient.

Maybe this is a stupid question but I've wondered about the advantages/disadvantages to having a 10 kw motor vs. 5 kw. My boat is 28', 8000#'s of displacement so let's assume hull speed is 6 knots at full throttle. From what I've read I know the 5kw will do the job. If you wanted to motor lets say at 3.5-4 knots for a long period of time would a 10KW unit run cooler & use less amps from the battery bank when compared to a 5kw?

Thanks,
Bob

Re: [Electric Boats] RE: CVT Transmission

 

Good answer, Mark.  I read on Green Car Reports daily examples of the lengths to which many are resorting to get in the way of Tesla progress.  All based on "that's not the way we've always done it."  Somehow, hobbiests, professional developers, and the general public at large have GOT to encourage innovation and trying new things.  Henry Ford ran into it with his Model T production line ("It will never replace the  horse.")  And now, marine electric propulsion advocates are bound to run into the same thing again.
