I've finally decided to address an item on the boat that's been concerning me for some time: replacement of the forestay, hidden for years under an ailing and worn out CDI furler.

After removing the old furler I decided I didn't want it back on, so spent some time researching and decided on the
Harken MKIV Unit 0 model.
My rigging wire appears to be the original sized 5mm diameter 1x19 stainless steel wire. The nearest size to this is Imperial measure 3/16", which is slightly smaller, hence weaker. Given the fact the wire is completely enclosed by the furler foil, and subject to more strain with the weight and windage of the furler, I chose to upsize to 7/32" wire.

I've always wanted to try swageless fittings for the wire ends, as they make it possible to repair rigging in the field (ocean?) without extensive tools. More research here convinced me that
Hayn Hi-Mod fittings fit the bill.
They have re-usable innards, and a unique crown ring that holds the outer wire strands perfectly even in individual grooves.
Unfortunately they arrived with the wrong sized crown rings, so I've been busying myself overhauling the rest of the standing rig, while I wait for the correct ones to appear.
