Just returned from delivering a boat to Sarasota. Big pass has got to be one of the worst marked passes on the entire gulf. One green marker was on dry land! The termporary markers were so small you could barely distinquish them from crab trap bouys. With all the boat traffic and quality of boats at Marina Jacks, looks like more effort could be put forth in marking a decent channel. Do not try to enter this pass at night or even low light conditions and certainly not in heavy weather.
