Thanks Dazz and Peter.

All worked well today with one exception. Because of the corrosion I had under the old one the new hook is a little lower than the old.

Having not moved anything at the bottom of the mast (hind-sight is a wonderfull thing) I couldn't get the sail flat enough which turned out to be pretty inconvenient in the 25 knots and 1.5m chop we had today.

Net result, 2 swims, a DNF, a DNC and a broken trap set up. On the upside I guess it's always good to get some righting practice .

Looks like another night in the shed. Ahh... the joys of sailing

Cheers
