I've now had the Blue Water Yachts bimini in "Silver" sunbrella for a little more than 7 years and have not treated it gently. It has been up on the boat continuously, all but about 20 days while trailering, in all conditions (snow, hail, 60+ mph wind gusts) and its still going strong. I have the BWY full enclosure and almost always keep the bimini, dodger and mid connector in use, taking down the mid connector while sailing. I initially thought not being able to stand under the bimini might be an issue (I'm 6'4"), but it hasn't really posed a problem. I would much rather have the full coverage of the cockpit than the ability to occasionally stand at the helm under the cover. I use my boat primarily as a sailboat and almost never go over 6.5 knots. My only complaint has been chafe from the backstay. After trying a number of different arrangements, I ultimately just enclosed the lower portion of the backstay in a PVC tube.
The BWY bimini seems to be designed to be the correct height for the boom to clear over the top while sailing.
