The Water Itself
The best cruise-ship pools are wonderful - four of them, flanked by 2,000 loungers. The best moment on a catamaran is 7 a.m., coffee in hand, stepping off your own stern into bathwater-clear sea while the bay is still asleep. Both are "swimming." Only one is swimming.
Same story with toys: paddleboards, snorkel gear, floating docks and a fast dinghy live on your yacht, deployed, included. On the ship, water time is an excursion - booked, priced, and shared.
