Manta Watch

No need to get wet! Watch the Giant Kona Manta Rays perform an underwater ballet while you stay dry, safe, cozy and comfortable on the decks of the glass bottom boat, Spirit of Kona. High intensity lights illuminate the underwater Manta Ray View via Glass Bottomscene. Watch through the large glass bottom windows as the giant manta ray enters and feeds on the plankton forming near the lights under the boat. Seen up close and just inches from the glass, the experience is fabulous. Snap photographs and video to take home to share with your family and friends,  and do it all while enjoying your favorite cocktail or soft drink.

Until the introduction of the Spirit of Kona, with its large glass bottom windows, the only way to see the Giant Kona Manta Ray was to get into a cold black ocean at night in scuba or snorkel gear. The Spirit of Kona is equipped with underwater lighting to draw in the plankton that the Giant Manta Rays feed on. It is the newest most popular way to view these graceful animals with the whole family, young or old.

Scuba divers and snorkelers in the water often unwittingly rub against the fragile coral damaging it. Boat anchors dropped on the reef destroy the fragile ecosystem beyond repair. View responsibly without all the risk to the reef and the life that need it to live. See the Giant Manta Ray from the decks of the Spirit of Kona. The most eco friendly and responsible way to view these amazing animals.  Manta Watch cruise.  Learn more
