Thee difference is that the Willie has a varible hull. It has a 32 degree bow and a 20 degree entry and transitions to 8 degrees at the back. The steeper angle at the front is for cutting waves/chop and 8 degree is makes it stabler and troll flatter. Rumor has it, with the motors up it will float through 8" of water.

I will be going for a ride in one shortly and guessing by the guide sales, they are a hit.

Plus you can get it built anyway you want with any option you want.
