The Pyranha Grumpy Deck is ideal for those who have trouble putting on full-reinforcement spraydecks but still want to invest in a deck that will be dry and cope with regular usage. An inner latex coating to the rim area grips on to the cockpit, preventing implosions and creating a better seal on the boat, and 4mm dive-quality neoprene throughout with stitched and glued seams make this deck suitable for the rigours of whitewater. Printed edge protection increases the Grumpy Deck's durability so you know it'll remain dryer for longer. All Pyranha Spraydecks are designed to give the perfect fit on Pyranha Kayaks, but most are equally well-suited to other brands of boat too.
