Dennis, that class ruling was in 1992-1994 time frame I think. We attempted to cover the chafing with a peice of metal. In 2001, the class also ruled against the metal as well. So we simply allowed the chafing.

There are probably several ways to accomplish the same goal. On loaner boats, Zephyr uses a low tech method of tying a block to the primarys with a North Sails sail tie.

The complete goal here is to sail the boat flat when the wind is on. This is harder to accomplish if the #1 is trimmed from the low side.
