I know if you hit a "Hole" in the corner when entering at full speed(like I did last weekend), you're boat takes the turn like this!! Enough force to put a hole in my sponson!:eek:

the turn is more easy or this hull is verry dangerous ? :confused:

Don't know yet, but will see what happens. This is a Sport C boat, similar to your S550 class.
