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!

We were a group of nine ranging from 10- 70 years old. As always, they made it safe and funny for everyone. They are great naturalists, pointing out and explaining just about every piece of marine life.

My family and I recently signed up with Mauna Lani Sea Adventures to see whales off the coast of the Big Island. As it turned out, that afternoon trip did not have enough customers, so they called and asked if we would be open to a combination snorkeling/whale watching trip the next morning. I'm so glad we said yes. The... More

I am a diver with over 500 dives and have reintroduced my partner to this wonderful sport. We chose to go with Mauna lani divers in November for a couple of check out dives. The folks were brilliant. All the gear was well maintained and newer and more importantly the crew was engaging and concerned about ensuring your safety as... More

I booked a "sailing" trip for my son and his fiance and what they got was not a "sailing" trip but a motored trip out and back. I wish tour operators would be honest and not use "sailing" when it is not sailing.

Kawika R, Owner at Mauna Lani Sea Adventures, responded to this review

Aloha Swimmeer52, I am sorry that your trip you booked aboard WINONA did not have any "sailing" time. It sounds like we miss informed you about our sunset or snorkel sail. During the winter months we are graced by the beautiful humpback whales that migrate down from Alaska to give birth or mate here in the warm Hawaiian waters. During... More

Whale watching with Captain Don, aka: The Whale Whisperer, and his crew, Ray and Joey, was a wonderful experience and one my family and I will never forget. This was my fourth tour on the Winona catamaran and I will never tire of it. The whale activity was at its highest with calves, mothers and males breaching and tale slapping... More

There are basically two choices for whale watching if staying in the Mauna Lani resort. This company offers essentially the same experience as the one down the road but is less expensive, offers more afternoon sailings and is really convenient if staying at the Mauna Lani Hotel.

The wonderful family and crew of the Winona from start to finish of the evening sunset trip are first class. We have been on this cruise for the 5th time in the past few years. We tried one other company before trying the Winona. What a difference!! We will continue to enjoy our trips with them and share it with... More

Went diving with this company a few years back. We were so impressed with their excellent service that we couldn't wait to return. We hoped our second trip would measure up to the memories we had of the first trip. were we disappointed? NO!!! We were so thrilled to see our favorite dive masters, Gary and Steve still hard at...

We went on the whale watching trip and everything was great. There were 33 of us onboard but didn't seem crowded. Served beer, wine, soft drinks and chips. Spike was very knowledgeable about the area and spotted several whales for us. Very professional operation and well run.

Great crew. Great boat. Great snorkeling and whale watching and sunset cruises. They have everything on board that you would ever need. We did them all and will do them again.
