The bow cuts a clean white wake across Casco Bay as gulls wheel overhead and the granite walls of Fort Gorges come into view—a squat, circular relic staring back at the mainland like an island-sized gear from another century. On a two-hour cruise from Fore Points Marina, the coastline of greater Portland unfolds in close-up: spark plug lighthouses, shear cliffs, and small rocky stages where seals haul out, sunning themselves into indolent poses while the boat’s hum keeps a respectful distance.

Fort Gorges was constructed during the Civil War to guard Portland Harbor; lighthouses in the bay date to the 19th century and were vital for guiding shipping into one of New England’s busiest ports.
