Abstract: The cringle or grommet disclosed is adapted for applying substantial loads to a fabric sail such, for instance, as a main sail or a genoa jib, and may be located at the clew of the sail to which point some rope or the like is attached for trimming the sail. The cringle employs a pair of complementary ring members, one on one side and the other on the other side of the fabric of the sail, each having a multiplicity of holes therethrough which are in registering relation and through which holes there is located rivets to clamp the rings together on the sail. The rings may be applied to the sail before an opening through the rings or through the sail is made after which an opening is made through the rings by a heated tool guided by the inner edge of the rings, which step melts the synthetic fabric of the sail so that the melted thickened periphery enters the chamfered inner edge of the rings, thus assisting in applying more resistance to a sail being pulled from between the rings.
