The previous cap had a curved hole through the plastic to accommodate the halyard. The hole led the halyard from the sail up, over, then back down into the forward grove of the foil. At the same time the hole avoided interference with the forestay by curving out and around it. The result was substantial friction when hoisting the heads'l. This new design adds a sheave to support the halyard, reducing friction substantially. This make it much easier to hoist the sail.

It is used on the FF2 furler typically found in our Capri 18, Capri 22 and Catalina 22 Flexible Furling gear kits.
