The Pyranha Grumpy Deck is ideal for those who find it difficult to put on fully reinforced spraydecks but still want to invest in a deck that is dry and can cope with regular use. An internal latex liner on the edge area adheres to the cockpit, preventing implosions and creating a better seal on the boat, and the 4mm dive quality neoprene with stitched and bonded seams makes this deck suitable for the rigors of white water. The printed edge protection increases the life of the Grumpy Deck, so you know it will stay dry longer. All Pyranha Spraydecks are designed to perfectly fit Pyranha Kayaks, but most are equally suitable for other boat brands as well.
