. We have a 34'sabre. Overall I am very satisfied with the cover. It comes with an aluminum frame that is color coded and relatively easy to install. We are going into our fourth winter and it has held up. I can install or take down in an afternoon. Time includes storing or removing from the basement. I have easily put the cover on and off by myself but it is far easier and more efficient with my wife. The cost for the entire system was 2562.00 (US dollars). The cover was shipped common carrier to Nantucket, Massachusetts. It is far better than shrink wrap, especially with landfill space or finding a recycle center that will take shrink shreds.
