This is a brand new spray deck that was ordered by a client and returned for fit reasons.  It is a brand new keyhole spray deck, neither of us can remember what the kayak was that this was supposed to fit.  I have included some pictures of measurements.  The length of the deck unstretched is 28" and the width (unstretched) is 17".  The waist is not adjustable at a circumference of 36".  If you think this mystery deck will fit your kayak, then it is a deal for you!
