Welcome lbiexit63
Your choice to refurbish a 20' SeaCraft is a great choice. I fish Charlotte Harbor a few times each year. If I can get up close on Bokeelia Flats on the north side of Pine Island in my 23' a 20' would be no problem. There is some good Snook and Trout holes within Bull Bay that would be easy target on the start of the ebbing tide. Fishing the pass of course would be no problem and given decent weather, the off shore wrecks would put some tasty grouper on the plate. You need to pick the brains of CSC members "Briguy" and "Snookered" too give up their honey holes (yeah right)Good Luck with your endeavors
