Re: Mariner Roller Furling
I have mariner roller furling on both the headstay and forestay of my cutter. The stays do rotate and the sail furls around the stay. The sails have 3" webbing strops that go around the hank and velcro back to the sail to protect the cloth from the hanks. This is the furling system that Steve Dashew had and recommended on his first cruising sailboat, Intermezzo a 50 foot Tripp designed Columbia. My boat is a 40-footer and I have cruised over 25,000 miles of blue water in the South and West Pacific. It is true that you don't get quite the same consistent furl as with a foil and in strong winds the foot and head will star to furl a little earlier than the middle of the luff but this never presented any problems. The Mariner system has some nice advantages. First, all the parts are very simple to make in any machine shop with the exception of the bearings which are standard aircraft bearings and available at any bearing shop. Second, since the sails are hanked on, if you have to take them down in heavy conditions, the sail stays under control as it comes down and can't get away from you like a taped luff sail can. If I were to buy a boat with a Mariner furler on it I would not chuck it for something else.
