Re: [Electric Boats] Props

Thanks Dan.. If we can get about 3 kts at 20 amps draw that would get us into the longest inlet on the US east coast..Since we are going to be full time cruising live-aboards again really need to keep the current draw down underway.What is very little draw for you? From our past experience we get by on a 65 watts of solar unless we have to run the radar. Richard

Richard I think it is going to depend on what you expect while motoring. Here is a spreadsheet you can use to figure out what you may get. If you email the guy that did the spreadsheet he will send you an updated one that you cannot distribute. He only wants the real numbers you get once you get set up. The other thing you can do is just run the prop while sailing at a very low rate just enough to negate the drag. It does not use that much juice.

Greetings all
our boat that we are converting to electric power is an Alberg 30. 9000 displacement (until we add our cruising 21'8" water line (when not healed)
Question is regarding the prop.Since we want to stay with a 2 blade (want to keep the amazing light air performance with the prop hidden behind the full-keel) and can go no bigger than a 13" it was recommended that we go to a 13x12 to replace the current 13x7
i would love to know what anyone with a simiular sized boat is using

Thanks Richard
