Gary I had one custom made
for my 260.I unfold it from the bow to the stern alond top of the mast.The cover goes down to just under the rub rail. There it has a hem with a draw rope that comes out each side at the stern. Bits of valcro every 5 feet secure it around the mast.It extends at the rear about 3 foot so the stern is covered.We try to cover up at every opportunity for the sun down here sure can do a lot of damage.Even when the wind and rain get to storm force the cover remains on and of cousre is fully water proof.Cost down her just over $1000.00aus.Might be worth checking out a quote over there!
