I am looking to repower a 22ft Norwegian wooden boat with an electric motor. The boat weighs in the 2500-3000 lb range. The 5kW thunderstruck kit would probably do, but their advice is to get a 10kW kit because the motor is air cooled and not sealed. I am ok with that advice. This is not a sailboat I am looking at continuous power draw for 4-5 hours. On a sailboat I have used a Minn-Kota for getting in/out of the marina with good results.
The question comes to sizing the battery pack. Does anyone have real world numbers for speed and amp draw for a small boat like this? My goal is to be able to cruise 20nm, perhaps 30 in a stretch. I am thinking somewhere in the 4 kt range.
Secondly, any real world experience using a regular 2000W generator to power the charger while the small boat is underway?
Any guidance or pointers appreciated.
