Re: [Electric Boats] Re: How Much Thrust is Enough

 

That makes me wonder about the qualifications of the person answering the question. Near as I can figure, the geometry of the prop and prop support should control reversing.

Weeki Wachee State Park, Florida, had electric 'jungle cruises' going up/down a 3 ft deep, 2 mph river.  Then the state switched to new boats with 60 hp (I think) outboards.  I asked why the electrics were replaced and the answer I was told, was that the electrics took too long to bring to a stop (by reversing), so that if a kayak crossed the bow, the electric boat could not be stopped safely in time.  It was a liability issue.  So, consider not only currents, but also speed bumps (kayaks).
