Probly not, They won't deliver the discharge rates you need in a boat.

Those cells are probably only good for 3C max, i.e 6.6 amps. If you made up a pack of 4 with 2 series and 2 parrallel, you might be ok for a speed 400 application. There are now LiIons available (Kontronic and Saphos) in 1100 mAh capacity rated at 10 C.
