All the big cruise lines have answered the call of golfers. Norwegian, Crystal Cruises, Silversea, and others have golf pros on board year-round to give lessons and offer swing analysis. Norwegian Cruise Lines' Pride of Aloha has launched the first Pro Shop at Sea. (You can ship your new sticks home.) Many ships also have golf simulators, allowing golfers to “play” some of the most famous courses in the world, and Silversea even has driving cages and practice greens, and offers clinics and demonstrations.
