Topic : Epoxy?

When people say that they've epoxied the hull, do they mean that they have stripped it back to the bare bones and painted epoxy resin straight on to it and then painted over the top??

More or less...or it should! See the link below. Epoxy will stick to anything (almost)so you don't actually need to go back to bare wood but failure to do so will potentially lead to problems as the old varnish/paint will eventually lift, often during the process of the epoxy curing, leaving an area of failed adhesion to the substrate (the wood of the hull, decks, etc). You could just apply epoxy but, as it isn't UV resistant, it'll evetually degrade in the sunlight, hence varnish or paint.

Unless they were referring to a 1980s boat where the cascamite has given up, and they've had to reglue half the joints with epoxy. That could be another interpretation of the phrase.

Guess what I'm looking at this summer?!

Righto, mine is 78, winderbox. So maybe next winter I'll strip it back and go for it. 
Do you just brush it on?

Brushing, rollering and spraying will probably all have their advocates. The CVDRA (link below) live and breathe to restore, renovate and race boats of a similar vintage to yours - post on their forum and you will almost certainly hook up with somebody who has done exactly what you are proposing. 

Notwithstanding the above, I'm sure you are about to get a lot of useful info on here.

I was referring to the use of epoxy to re-glue failed joints in 1980s boats.

I'm not sure epoxy coating (just "brush it on") is quite so suitable for an older boat as they flex more, and the epoxy dries very hard. Single-pack varnish has a bit of 'give' in it.

Modern boats are very stiff and thus epoxy coating, with two-park varnish on top, is a great finish.

Most of the old wooden raters have been sheathed in epoxy, Vanessa being the exception.  They have a fibre glass matt under the epoxy though.

:-) More questions. 
1. I have a highfield lever for the jib. Could I rig up a cascade system to a cleat off the halyard to create tension to make life easier?
2. Is it not the done thing to use a spinny sock? My spinny just sits on top of the front tank and into the front of the crew's area.
