Banana boat (boat)
A banana boat (or water sled), is an unpowered, inflatable recreational boat meant to be towed. Different models usually accommodate three to ten riders sitting on a larger, main tube and resting their feet on two laterally flanking tubes which stabilize the boat. The main tube is often yellow and banana-shaped. Some models have two main tubes. See also. Inventor of the banana boat was Walter Kamakau Napoleon in 1971, from San Diego, CA.
