Pontoon boat rentals, both standard and double-decker, are available for full- and half-day rentals. Shell Island boat tours allow you to sit back and relax as you take in the sights of St. Andrews Bay, with snorkeling in shallow waters as part of the fun. Adventures at Sea also offers jet ski rentals, wave runner tours and fishing charters.

One of the newer kids on the PCB block, Papa Joe’s Bayside, is as much about its water-activity rentals as it is the other goodies it offers at its beachside location overlooking St. Andrew’s Bay.
