The Myrtle Beach community of Little River is the only homeport in South Carolina for a casino boat. The 400-passenger Big “M” Casino Boat II sails 11 a.m. to 4 p.m. daily except Monday and adds a 6 to 11 p.m. trip Thursday through Sunday. Gambling is casino-style and begins once the boat is 3 miles offshore. People need to be 21 or older to board. Gambling includes dice, cards, roulette and slot machines, and food and drinks, including alcoholic drinks, are available.
