The Geminis "bucket" is not exactly a sled. The best sled design I have seen is on Jim Browns trimaran
, Scrimshaw which is a nice boat shaped design that floats the weight of the motor
so you don't get ventilation of the prop. The bucket on my Gemini
works quite well though and after motoring 1500 miles in 2013 I really had no ventilation problems but the thing could sure use a nicely faired bottom shape as it pounds something fierce in any sort of chop, it is flat on the bottom which will need to be improved on at some point.
