Sailing daily from MacMillan Wharf and stretching 39 feet lengthwise and 16 feet abeam, the Coast Guard–approved Viking Princess accommodates up to 42 passengers and two crewpersons per cruise. Several different cruise formats introduce water wanderers to coastal views of varying sites, such as Cape Cod’s prime real estate, well-known lighthouses, and hidden Provincetown gems. The Princess also embarks on festive holiday-themed voyages, such as Fourth of July or Tax Day cruises. Cape Cod Life's 2010 Gold winner for Best Kids' Activity, the Critter Cruise invites wee ones to pull up lobster pots and bottom dredges from the waters and safely inspect and handle the findings— such as blue fish, sea turtles, or humpback whales—alongside an expert naturalist. The Princess is wide enough to facilitate groups dancing to the sounds of the ship’s overhead stereo or to the tunes of local musicians during live-music cruises.
