Boat tests usually involve a squeaky-clean boat just out of the factory with low engine hours. This wasn't one of those sea trials. T.J. O'Shea, a charter captain in Clearwater, Florida, took delivery of his Southport 33 Family Edition last August. By the time I climbed aboard three months later, the twin four-stroke Yamaha 350s had more than 500 hours on them. "A lot of those hours were hard," says O'Shea, who spends most days offshore fishing or diving. When he's not chartering, the captain uses the boat with his family. The 33 FE is O'Shea's second Southport, the first being a 29-footer that remains in his fleet with more than 6,000 hours on it.
