Bankbound,

The hull gauge is .100, sides are 21" high.
Is it a thick skinned V'd boat?....No. But I have never felt unsafe in it. You're definately closer to the water than you would be in say a semii-v but I have never had any problems with wakes. I fish the Cowlitz quite a bit and that place is a wake factory.
As far as a load of three guys goes......that depends on the size of the guys. This boat is pretty much a two man show, but if all three were a little on the smaller side, it could be done effectively.

Thanks
RL
