I follow with what you are saying. I believe that weight has alot to do with ride quality, strength and durability. If you are looking for the 100mph mark then sacrifices will have to be made. Most of the sacrifices will be made in your wallet. But others will be made in the handling and the ride quality. It just depends on what you want out of a boat.
You already own a nice riding boat. I would enjoy flying your boat more than I would enjoy a 100mph.
There are alot of quality products out there. It just depends on what you want.
