Takes seconds to put in place and seconds to remove and store when your boat is running. Gullsweepr performs best when it is level to the water. - Designed for those situations over canvas where one does not want to put a hole in the canvas to locate Gullsweep. - The GS-FM is able to be pulled into location and tied down using rope loops, without a lot of rope pressure on the canopy or bimini top. Weight 3 lbs. The base is filled with sand which shapes easily over any irregular canvas support members.
