I just installed a new Bimini on my 2002 Hunter 270 (which is basically a 260 model) with a one inch stainless steel frame. I also installed stainless steel tubing (from the bimini frame to the stern rail) as struts on the rear and front of both sides in order to add rigidity and get rid of the straps.
I went with the one inch tubing and struts as we use the bimini frame as a support to help us get down from the high cabin top (we try to use it as a balancing point and not put much of our weight on it, but there are times !!). The previous 7/8 inch aluminum tubing was just not strong enough if we lost our balance & had to put more of our weight on the bimini frame. The new set-up is very strong. As I approach 70 it seemed to be a prudent investment to keep us sailing.
