I wouldn't be afraid of a bigger boat in the rocks either. I fished out of a 24 foot deep V in the rocks a lot this year. I was more then a little gun shy at first but I eventually settled into all the pocket water I used to fish with a smaller boat. Still, a 21 would probably be more appropriate for scooting amongst the rocks.
In any case be afraid of the fuel docks, not the rocks, as the boat gets bigger...
#^^^^^^&, look at a deeper V as well as a bigger boat if pounding through the Bay is a big concern.
