Re: [Electric Boats] West Marine 2010 catalog Page 759

 

Looks like there will be a "sea change"  coming to the boating industry with this news.
I read a book called FASTER by James Glick about how change occurs much faster these days thanks to technology and communications. I expect that will happen in the electric boating side of things. This should also help produce new innovations hopefully in battery technology for marine propulsion systems which will benefit us all.

I was happy to see our happy little forum listed in the just released West Marine 2010 catalog. More so then that you can now buy multiple Mastervolt electric motors from your local West Marine! They are now selling the Aquapella, and Aquapella Hybrid drives. I was a little bummed that they do not yet sell the SilentProp 10.000. Which is the Mastervolt I'm most interested in.

One of the most interesting thing about the article was the section on "Trust vs Horsepower" They did a pretty good job of explaining the difference in power ratings between gas engine HP and electric ratings in watts. They listed a "rule of thumb" I have never heard before but sounded plausible.
The rule goes you should have about 1000 Watts of electric motor for every ton of displacement of your boat.

So using this rule my Chris Craft with a displacement of 26,600 pounds = around 14 short tons would need at least 14000 watt motor. Which is a little less then I plan on putting in. I plan on putting in 2 10000 watt SilentProps. Which makes my feel better about my own plans.

I'm guessing we may get a flood on newbies in the next few months, should be fun.
