This is the largest board in the Xcross series. Designed for the larger sailor who wants a board that has the volume to carry them through the lulls but still be able to carve the board in turns and have the control when the wind does pick up. The flatter rocker gives this board great acceleration and speed but with the thin tail rails and double tail concave it gives you the control to push this board to the maximum. Sail Size 9.5m to 5.5m
