We strongly recommend the use of tuttle head box boards against powerbox models.

in case you use a powerbox board make sure the fin box is strong and we recommend to secure your foil with a rope leash.

The powerbox head shall only be used with our extra load plate to spread the efforts across the board and reduce the risk of board failure.

These customers had an ancient Windsurfing board with a power box fin box. They also had a small inflatable with 10hp engine. Rather than buying a new board or doing major alterations to it, we were able to fit them out with a Mantafoils SUP XL wing and Power Box Head and Special Load Plate and like magic they can Fly!
