No Experience Required

The RIB skims the gray-green edge of Portland Harbor and the city unspools behind you—brick warehouses, the working waterfront, a gull that seems to decide your route. Within minutes the rhythm of the engine replaces traffic noise and Casco Bay opens: scattered granite islands, squat fort ruins, and lighthouses marking edges where tides push and backs off. On a 14-passenger rigid inflatable boat, the captain steers a line through currents that shape Maine’s coast and every passenger gets a front-row seat.
