High performance 7mm dinghy sheet. Does not kink or absorb water and is easy to taper thanks to thicker Dyneema core and thinner cover. Chunky, high grip, blended cover of Dyneema and Polypropylene means great performance through ratchets and cleats with high resistance to abrasion. Excel Matrix was developed and chosen by the world's best dinghy sailors. The sheet of choice on board many RYA Team GB boats.
