Some sails I'm very fond of and have plenty life left in materials. But lately I've had 2 2006 KA's break the downhaul pulley.
with these I ditched the 8mm tube and replaced with a 8mm 316 SS bolt but Tig'd the washer on to keep compact.
would love to hear other tricky repairs to keep kit keeping on.

That's one all us Ka sailors have done at some stage

Quick and dirty hacks.
