Paddlebuoy paddleboards are 9.5' x 24" and are used both as a lifeguard's rescue board and as a recreational watersports board. The boards come in 4 models, and have been in use since the 1950's. Versatile and durable, the boards have helped in the recent resurgence of stand-up paddleboarding. Paddlebuoy, of Elk Rapids, Michigan, is the world's oldest and largest manufacturer of polystrene paddleboards.
