RE: East side of Pine Island Fl.
Jon, in Jan 2000 I cruised up the Matlacha Pass from the ICW as far as the bridge, we anchored on the south east side of the bridge and returned south to the ICW the next day.
this was in a GB 36, 4' draft. We bumped bottom a couple of times but were able to keep moving on. I don't know how depths are North of the bridge.
We are in Sarasota heading South on Sunday I'll check with you next week, say hi to Candice and JB for us.
