I am the proud owner of a cold-moulded, mahogany hulled 1975 racing yacht. Her topsides are treated with a two pot varnish which is beginning to fail. Must I continue with the varnish treatment or are there alternatives?
Not more varnish!

Yes, paint is a real alternative. Seriously, a mate of mine was in a similar position, with a cold moulded varnished hull. He changed to paint a few years ago and has never looked back! As she's cold moulded she's probably very fair, and you will not get the movement which fractures a paint finish along the seams of a carvel hull. So, you're bound to get a great finish.

Or you could do the West System type of clear epoxy.

Being built in 1975, it wouldn't be suprising if she has had this treatment once before as the West System was pretty exciting stuff back then, especially in cold moulding. - Just a thought.

May I suggest Coelan?
This is a rather clever German one pot stuff which I suspect is polyurethane based; it is fearsomely expensive and requires care in application; my own experience of it is that it is a good deal tougher than two pot polyurethanes, and retains a high gloss for longer.

Coelan
It cannot be used below the waterline, though, can it? Or is there a form of it that can? I can't remember now. I do know that I have a ton of it (thank goodness for overtime) and will be spending most of the winter with a large bit of sandpaper in my hand and teak dust in my eye...

Sorry, I should clarify...
...what I meant was, I thought it couldn't be used near the waterline, in anywhere likely to be a wetted area whilst heeled. Having said that, I can't think why not. I've never really understood how to prepare a varnished ull - I presume you still use primer and antifoul 'neath the waves?

Correction.
Sorry, a correction to my last.
Those earlier epoxys degraded in sunlight over a period of time, not very long really, so it was unlikely to have been finished externally with clear epoxy. Possibly built with it, but not sealed with it. Sorry. What was I on?
