[Electric Boats] Re: electric prop and re-charging

 

The the web page of the commercially built ElectroBay 23 by Ray Electric Outboards, Inc. says this boat and electric motor has a range of 46 miles at a cruise speed of 5.8 miles per hour with 8 batteries and a range of 98 miles with a 16 batteries.

The visual appearance of the ElectroBay 23 is quite similar to the Atkins tunnel-stern Everhope.

My assumption is that on a calm day, with an average speed of 3.5 or 4 mph, the range would be somewhat further.

For this electric boat endeavor I'd likely have a gas 2 or 3 horse stowed in a side locker, out of sight, in case of 'system failure'.

I lived Thomasville, Georgia and visited the late Robb White's workshop before starting on my first canoe, 2 hours with him was like a graduate how-to and how-not to full graduate level class.

Over the past 25 years I've constructed 9 canoe or bateau type boats, the largest being 20+ feet. After construction, most have been used for ten or twelve day fishing/canoeing treks in Georgia/Florida/Ontario in fresh and salt water.
