The Roundy surfboard is perfect for anyone who has experienced the pain from banging their foot on the tip of a typical fish tail. The Roundy solves that problem with it smooth round tail. This surfboard cuts back smoother than a fish tail, while still providing plenty of drive off the bottom. It works well as a tri fin, but can be ordered with 5 fin boxes for multiple fin configurations. This is similar to a biscuit and is a board that anyone can ride and have a lot of fun.
