the best place to get a bimini for your sea ray is to go to a custom canvas shop and have one made for you boat out of sunbrella fabric its the best also have a stainless steel frame built for the bimini if your going to want a full enclosure later on have them put zippers on the bimini hope that helps. p.s. i work in canvas shop and have been making marine canvas for 20 years
