This vessel was custom designed for small group whale watching and snorkeling adventures. We get a lot of comments about how comfortable Kainalu is compared to a raft. This is because with a Deep "V" design and heavier displacement Kainalu is able to cut through light chop with ease. Rafts tend to bounce off the top of waves, as they are designed to be as light as possible and carry as many guests as possible. Kainalu is 12 feet across which helps add to her stability and for guests to be able to walk about the vessel and stretch their legs without stepping on other peoples feet which is not possible on any raft. Featuring a large swim step just inches off the water with twin swim stairs makes getting in and out of the water easy. For those times at sea when nature calls Kainalu also offers an onboard restroom and freshwater shower (which you won't find on many of the medium-sized vessels) which are a must for a long day on the water.
