Have used my Minn Kota 40# thrust on my 9.6 ft. air floor inflatable
for the last few years going up/down northeast coast.
For protected anchorages/waters, slow go but beats rowing, actually faster. Is fine if you have no great expectations of speed.
I use as am limited with space/weight on my smallish 30 fter and prefer not to carry gas on board.
Use small/lighter 35ah battery for short and larger/heavier gp 24 deep cycle for long (which also connects to my house bank for extra amps and charging
Thought could be problem keeping batteries
charged as i am at a mooring and then at anchor
but seems to be working out, have used for a few years.
