The $31k is roughly about twice the typical C-16 price, but there's a large range based on age, equipment, condition, etc.
The Torquedo components are quite expensive, and I imagine easily come up to close to $16k when all the components are added up, and the installation miscellaneous costs (wiring, busses, fuses, boxes, fasteners, etc., etc., are included.
(Greg (Aurelia) would be a familiar source able to evaluate this.)
So what's the RANGE of this set up (says suitable for local waters)? 5? 10? 15 Miles? And how about the speed limitations? (Probably should be using a long, narrow, displacement hull.)
Note that the total hours on the present set up is 2 (TWO)! Must not have been very satisfied with the performance???
The Torquedo motors and Lithium Ion batteries are pretty much state of the art. The range and speed limitations of this set up typify the engineering problems faced by designing electric alternatives to combustion motors. Progress is being made, but it's a difficult challenge.
Very interesting find, though!
I've thought about taking an older swing keel sailboat and converting it over to an all electric fishing/trolling boat for inland lake use, but never did more than play with it on the drawing board. (Limited application concept.)
