A banana boat (or water sled), is an unpowered, inflatable recreational boat meant for towing. It was invented by Glenn Matthews in the late 1980s. 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. During the ride, the driver of the powered boat attempts to flip the banana boat upside-down by doing sharp turns. Riders should always wear life jackets for safety reasons.
Riding in a banana boat is considered to be a safer activity than water-skiing or other towed-water sports, and is similar to tubing. It is generally safe to ride at 4+ years.
