This site sells them
I don't have a 260. I have a 94' H26 and I purchased the seven foot bimini off this site and it works great. My wife won't sail unless it's out. It covers from the stern rail seats to almost the companion way cover. I had to put a second hook on the boom for the main sheet two feet forward to clear the bimini, I also use the hook for the first reef point sheet as a bonuse. That way all I have to do is reattach the main sheet when the bimini is not up to the original place. Good luck it is one of the best things I have done to the boat.
