You’ve never been on a boat, you don’t want to be on a boat, but here you are being dragged aboard one. Why are you boarding this weird-looking vessel? It guarantees that you’ll be “seasick-free,” that’s why. The 140-foot-long Navatek I isn’t even a boat; it’s actually a SWATH (Small Waterplane Area Twin Hull) vessel. That means the ship’s superstructure—the part you ride on—rests on twin torpedo-like hulls that cut through the water so you don’t bob like a cork and spill your mai tai. It’s the smoothest ride on Mamala Bay. In fact, Navatek I is the only dinner cruise ship to receive U.S. Coast Guard certification to travel beyond Diamond Head.

Sunset dinner cruises leave Pier 6 nightly. If you have your heart set on seeing the city lights, take the Royal Sunset Dinner Cruise, which runs from 5:30 to 7:30pm. The best deal is the lunch cruise (which runs during whale season, roughly Jan–Apr), with a full buffet and a great view of Oahu offshore—plus you get to see whales, to boot. The lunch cruise lasts from 12:15 to 2:30pm. Both cruises include live Hawaiian music.
