Welcome aboard Winona, our 50-foot, Polynesian style sailing catamaran...

Welcome aboard Winona, our 50-foot, Polynesian style sailing catamaran! Winona is U.S.C.G. Certified for a maximum of 49 passengers, with plenty of room to comfortably accommodate large groups while still being cozy enough for smaller, intimate gatherings.

She has a 3/4 covered cabin area to protect you from the sun and wind, and her large viewing windows allow you to still enjoy the views outside from her covered seating area. Her open deck is spacious and provides plenty of outside seating and areas to sunbathe. Winona's "Stairway to the Sea" allows easy access to and from the ocean for snorkelers and swimmers. She is equipped with two restrooms for your convenience.

The dress code on Winona is casual to resort attire. We suggest flat, soft-soled shoes or sandals. Hard sole or high heel shoes are not recommended. Winona does have nonskid decking so bare feet are welcome. We recommend you bring along sunglasses, a hat or visor, waterproof sunscreen and a beach cover up to help protect you from the sun. Towels are provided.

Our helpful staff will provide instructions and then equip you with all you need for a spectacular snorkeling experience! Mask, Fins and Snorkel sets or View Boards with built in windows are available to start your adventure. We offer everyone a safety vest and defogger to help keep your experience both safe and fun!

If you would like a special keepsake of your group's event, let us know. We can arrange professional video services (above and below the surface) for your group at an additional cost.


For individual travelers staying on the Resort's grounds, the hotels provide free shuttle service to and from our departure and arrival locations.

Our Captains and Crew look forward to assisting you in creating wonderful memories of your stay in Hawaii!

I did a two tank dive in mid-November and had a great experience. Captain Gary and Divemaster Jay we super friendly and helpful. There were only four of us diving and the small boat was comfortable with six people, I don't know if they use a larger boat or if they keep the groups that small. It was nice diving... More

The Resort Owners try to keep The Beach Club exclusive and do not make it easy for you to access in daylight hours as there is a security gate at the end of S Kaniku Drive. Also adjacent to the beach is Napua Restaurant and beach parking is provided, so buy yourself a cool drink and enjoy the beach by... More

The Winona is a catamaran that departs from the Mauna Lani Beach Club. The boat had about 25 people on it and included free open bar (no red wine), a deli platter and credit. The boat wasn't as nice as I expected with plastic "pew" seating and only room for about 10 people to sit on the front of the... More

Great dive instructor, ensured that you were 100% ready prior to stepping. Made for an awesome experience that I will never forget. Now that I am back on the mainland I am strongly considering earning my scuba cert.

Loved these guys! Hat goes off to Gary who I did the PADI open water refresher with. Great guy who has buckets of patience with this diver who struggles with claustrophobia. My husband did two dives with Gary and crew and saw crazy amounts of turtles and manta rays.

My family of five stayed at the Mauna Lani Terrace Condos for a week in July, and this dive shop was an easy five minute walk away. My 11 year old son got certified by Jay, who did a great job helping him through his initial trouble with equalizing. Jay developed a great rapport with my boy, and the whole... More

Took a Sunset Cruise up and down the coast near the Mauna Lani. The crew was friendly and attentive, and the scenery was wonderful. Drinks and pupus were delicious, too.

The boat and crew were perfect for our snorkeling cruise. They attentive, safety minded and fun. The boat was beautiful and designed for the purpose. They took us to one of the best reefs in Hawaii. Well done Captain Spike and crew.
