Thanks for your reply, John, and yes it does look like a no brainer. Changing subject slightly – is your keel coppercoated and if so what state was it in when you last lifted?

The reason I ask is that we have rust patches on the keel in the area of the hull joint and even though we clear the rust and re-do the coppercoat, the rust patches are there again next lift. The coppercoat was done professionally and the keel was epoxied before coppercoating.

We have had coppercoat for 4 years now and apart from this one problem we are very satisfied it. A wash down with the pressure washer (done by boatyard) and a light abrasion with scotchbright and she’s ready to go.

If only we coud solve the keel problem.
