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.
Hi i discovered that the roller i have on my boat is a mariner and also discovered its discontinued, i have used with no mayor problems applying wd 40 to the hex bearing but would like to have some info to make a major service for the complete system, since it has 20 years on the boat. the good thing is that it still works.
I saw the posts on the subject explainig that its fully serviceable and spare parts may be still available but if you have any information on how to do regular service and lubbing it will be very helpfull, I have the advantage that since its a small Macgregor 26 Classic I can lower the mast with ease to service parts.
My first concern is the upper bearing for the stay.
