Body Glove’s Kanoa II, a 65-foot, solar-powered catamaran carrying up to 100 passengers, runs an environmentally friendly, 4 1/2-hour snorkel/dive morning cruise, along with shorter lunch and dinner excursions for those who just want to enjoy the views, as well as seasonal whale-watching trips; all depart from Kailua Pier. In the morning, you’ll be greeted with fresh Kona coffee, fruit, and breakfast pastries before sailing north to Pawai Bay, a marine preserve where you can snorkel, scuba dive, swim, or just hang out on the deck. Before chowing down on the deli lunch buffet, take the plunge off the boat’s 20-foot water slide or 15-foot-high diving board. The only thing you need to bring is a towel; all gear is provided, along with “reef safe” sunscreen. And if you don’t see dolphins, you can do a repeat cruise for free (the same is true if you don’t see whales on a whale-watching excursion). Dinner and lunch cruises feature a historian who points out some 50 significant sites on the 12 miles from Kailua Pier to Kealakekua Bay, where passengers feast on a buffet spread and enjoy live Hawaiian music by notable entertainer LT Smooth. Parents will appreciate that all cruises are free for children 5 and under. Note: The boat is wheelchair accessible, including its restrooms.
