River Rat vacation cruiser
- View SourceI'm getting serious about a build inspired largely by Phil's "state boat" series of low power sharpie designs. Intended use is for inland and protected near-coastal water vacation trailer cruises within a few hundred miles of Eastern PA (a lot of great destinations). Simple accommodations for a couple and two medium size kids for up to a week. We did a full scale mock-up in the yard last summer to get a good feel for the concept. See photo posted under the "River Rat" album and a video walk-thru link below.
Primary specs are about 27ft LOA (3 1/2 sheet sides) and less than 7ft beam. My question for all you experts is: which "state boat" hull would you start with? (assuming some scaling is OK)

The facts are the link appears to be for intermittent electric propulsion use on sail craft - ie. for short hops: "Perfect for lake sailors; plenty of power and range to get out to sail Enough range for weekend sailors to motor home, if the wind dies" - and shore power recommended. Note that Electric Yacht advise "For extended trips (sailing) away from home, a small gasoline generator can be used to charge the batteries through these chargers." http://www.electricyacht.com/faqs/battery-selection/ Why then add the $4000 for the hybrid drive to the ICE dollars on a power cruising craft? How many batteries by your calculations?

In many cases, a Parallel Hybrid works best, then again, in many cases, straight electric is a great solution. http://www.electricyacht.com/products/our-weekender-hybrid-systems/
