The Kamanu, a sleek 38-foot sailing catamaran, provides a laidback sail-and-snorkel cruise from Honokohau Harbor to the marine preserve of Pawai Bay. The 3 1/2-hour trip includes a tropical lunch (deli sandwiches, chips, fresh fruit, and drinks), snorkeling gear, and personalized instruction for first-time snorkelers; weather permitting, it sails at 9am and 1:30pm. It can hold up to 24 people but often has fewer, making it even more relaxed. Some morning cruises are offered with a swim with spinner dolphins, while the adults-only sunset cocktail cruises are sometimes paired with snorkeling with manta rays. Whale-watching is also offered in season. At press time, Kamanu Charters had announced plans to add Kamanu Elua, a Zodiac-style rigid-hull inflatable boat with seating, which will offer Kealakekua Bay snorkel tours.
