Made of stainless steel, fitted with nylon pulley. The “Sea Sure” jib furling system is designed to guarantee full reliability. The drum is closed and protected thus avoiding the line from getting stuck or twisting when opening and closing. It consists in stainless steel bearings for perfect functioning even when the forestay is under maximum tension. It is only 50-mm high thus allowing to install the jib very low, just above the deck in order for the sail to be fully efficient. It can also be mounted below deck by using an additional stainless steel extension hose. The jib furling system can wind up to 3.5 mm of 3-mm diameter line thus allowing the use of sails with approx. 3-mm long lower rim (length from tack to sheet). This length is shorter in case of lines with longer diameter.
