Trilogy offers our favorite snorkel-sail trips. Hop aboard its 50-foot catamaran for a 90-mile sail from Lahaina Harbor to Lanai's Hulopoe Beach, a terrific marine preserve, for a fun-filled day of sailing, snorkeling, swimming, and whale-watching (in season, of course). This is the only cruise that offers a personalized ground tour of the island, and the only one with rights to take you to Hulopoe Beach. The full-day trip costs $169 for adults, half-price for children ages 3 to 12. Ask about overnighters to Lanai.

Trilogy also offers snorkel-sail trips to Molokini, one of Hawaii's best snorkel spots. This half-day trip leaves from Maalaea Harbor and costs $95 for adults, half-price for kids 3 to 12, including breakfast and a barbecue lunch. There's also a late-morning half-day snorkel-sail off Kaanapali Beach for the same price.

These are the most expensive sail-snorkel cruises on Maui, but they're worth every penny. The crews are fun and knowledgeable, and the boats are comfortable and well equipped. All trips include breakfast (Mom's homemade cinnamon buns) and a very good barbecue lunch (shipboard on the half-day trip, on land on the Lanai trip). Note, however, that you will be required to wear a flotation device no matter how good your swimming skills are; if this bothers you, go with another outfitter.
