Norestar"s bimini tops protect you and your boat from the rain and sun while adding a touch of style to your boat. The bimini tops are easily installed by any boater, requiring only a few minutes to install and no additional tools. Best of all, they"ll protect you from the elements all while costing hundreds of dollars less than other bimini tops. When not in use, the bimini quickly folds into the included zippered storage boot. Each bimini canvas is constructed from top of the line 8.10oz (600D) polyester canvas which provides the ultimate UV protection. The frame is constructed from 7/8" aluminum tubing and all stainless steel hardware is included. When selecting the right size width of Bimini, measure the distance between the two desired mounting points (the beam of your boat does not always reflect this). The height of your Bimini will be 46" plus the height at the mounting points which is normally more than ample head room). When purchasing, please confirm you have ordered the desired width and color as it is easy to accidentally select the wrong size/color.
