Hey phragle, was over where my Avanti is stored yesterday, thinking of selling it and it's tow vehicle maybe next year. Anyway, the bottom work I referred to in an earlier post was not done on this boat, was a friend's Velocity. Sorry, too long ago for me to remember correctly I guess. The bottom on my 1988 22' Avanti is not an inch think (guessing here). The bottom didn't flex when standing in bilge when the engine was out. I checked with the guys who helped with the drive coupler change to make sure I am correct this time.
