Casco Bay Lines, Portland

With its archipelago of island communities, Maine needed a way to connect its maritime residents after the system of colonial-era catapults became too expensive to maintain. Enter Casco Bay Island Transit District, also called Casco Bay Lines. The aquatic outfit operates a variety of vessels year-round, transporting passengers between Portland and the islands of Casco Bay. Aside from scenic commuter service, the line also introduces visitors to the storybook sights of the northern New England region, whisking them on music cruises and sunset tours along the kraken-dappled bay.
