I'm not sure about credit cards, but here is the number: 850-419-6188. The YOLO rentals at the Watercolor Boathouse are open to everyone and do not require a house rental through Watercolor. The YOLO company itself is running the rentals at the boathouse. There are also lesson packages available. Rates start at $30/hr. for a soft top board, and $25/hr. for a YakBoard.
