Four Winds II glass bottom boat has a glass bottom viewing room that guests sit in!. Our viewing room is a 180° total-immersion experience. The 65 sq. ft. viewing room is made of clear plexiglass situated below the water line. Once you’re board, you'll soon discover why Maui's visitors consider this boat to be one of the best to Molokini and why we have become a local favorite too. With a crew that is dedicated to your needs and to providing you with the best time imaginable, the trips that she offers are always a family favorite! Four Winds II is fun for all ages.
