Editor's note: Blount Small Ship Adventures has ceased operations and is no longer in business.
Blount Small Ship Adventures has operated the 88-passenger Grande Mariner along North America’s east coast, on the St. Lawrence River, and in the Great Lakes since 1998. The ship (and the line's similar Grande Caribe) is nimble enough to travel the Intracoastal Waterway, Erie Canal, and shallow waters around Cape Cod, Martha’s Vineyard, and Nantucket, taking you places other cruise ships can't reach. This also means that space on board is tight, and the tiny cabins require a bit of getting used to for first-timers.
