Mainsail Rot

DACRON MAINSAIL ROT - Cruisers & Sailing Forums: "Chafe is a great sail destroyer. For those who sail wing and wing downwind, you need to have chafe patches on your mainsail to protect it where it may rub against aft swept spreaders. On Exit Only, our cap shrouds were an obstacle to running wing and wing - you couldn't get the boom far out without the sail chafing against the cap shrouds. It would take large chafe patches to protect the mainsail against cap shroud chafe. Because of this problem, we rarely ran wing and wing. Instead we used a double headsail for running downwind, and we did not raise the main."
