5 knots is the hull speed for your Badger. It is unrealistic to expect any motor/battery combo to maintain that speed unless you spend multi-thousands for the battery pack.
Ask if you can live with a 2 knot speed. If you can, then electric can work very well for you. I doubt that you will find any practical way to maintain anything much over 3 knots.
Below is what Torqeedo says you could expect from their setup with its 520wh battery.
The watthour requirements for speed/range will be similar with any small electric motor. You can ballpark figure that to maintain 5 knots on your boat, it will need 1000 watts for a 1 hour run. At one third hull speed, that total amount of battery power will run it for 10 to 20 times as long.
If you go to the files section and run the eboat power spreadsheet, you are going to come up with similar numbers.
Travel 1003 with integrated battery (29.6 V / 18 Ah)
Inflatable, dinghy, sailboat or daysailer up to 1.5 tons
Speed in knots | Range in sm | Run time in hours | |
| Slow speed | 1.5 - 2.0 | 15.0 - 20.0 | 10:30 |
| Half throttle | 2.5 - 3.0 | 8.5 - 10.5 | 3:30 |
| Full throttle | 4.5 - 5.0 | 2.5 - 2.8 | 0:35 |
I have a Wes Farmer Badger http://www.duckworksbbs.com/plans/wf/badger/index.htm with a motorwell and I am trying to decide what to to do for power.I would love to go electric but the outboards are very expensive.Would a large trolling motor work for me? I would like to travel at about 5 knots for as long as possble.I would like to use a rudder and have a controller of some sort about in the middle of the boat.Any ideas and what this would cost me?
Thank You
Mike
