Re: A54 Main Sail furling foil weak point

I do agree with the batten comments and ours were removed a while back.
Another source of foil abuse, I believe, are the final moments of the furling process. We are very careful to make sure the outhaul traveler never touches the bumper, and that we never tighten the last bit of the sail flat with the furler.

Hi all, and Bill. I agree with Bill about the battens.
However at risk of irritating you by repeating myself I will again mention the stiffness and strain put on the furler motors, gearboxes and foil by salt buildup in the bearings of the swivel at the top of the sails. I think every one has experienced stiffness in the manually operated mizzen furler. In my case so much so I feared damage. Now having rinsed both the gear box and the swivel with fresh water, allowed to dry and then applied silicone spray the mizzen only needs the locking pin removed and it self launches with just the pressure of wind. If the winch handle was left in place severe personal damage could occur by its rapid spinning. Because the mainsail and headsail are motor driven we don.t feel the strain but see it in foil damage. On the SM this is seen in the elongation of the holes connecting the foil to the gearbox. I lower all the sails periodically and rinse the swivels with a hose of fresh water. Furling the mainsail in a breeze is very noticeably easier after this is done.
Bare with me when I repeat that on a previous yacht, in the middle of a 1200 mile ocean passage the headsail swivel became totally jammed with salt encrustation and we had to physically unwrap the sail before we could lower it. Once the salt was washed out it was fine.
