All good advice James. No wonder you got an Amel after 40 years of varnishing wooden yachts. Loki’s are a treat for the eyes and deserve varnish. I can relate as the last big boat I owned with my brother before my first Amel was a Cheoy Lee Rhodes Reliant/Offshore 40 with about ten acres of varnish. That boat only leaked when it got wet…
Another negative thing about using a base coat of epoxy is that epoxy is much harder/stiffer/more brittle than most oil based varnish. Dropping a winch handle or the like usually results in the epoxy un-attaching itself from the wood. Also, where it gets really cold, I have seen all the epoxy base coat fracture which at best is unsightly and at worse means stripping it all to bare wood.
You need tactical nuclear weapons to get epoxy off teak.

My wife and I have restored and refinished wooden boats with lots of varnish over the past 40+ years. We have removed a lot of varnish was applied over epoxy by someone else. If your base coat fails, any finish applied on top also fails no matter how many coats of varnish you apply. The failure of the epoxy base coating starts by going milkly/opaque looking so even if the varnish is not peeling it begins to look bad enough that it should be stripped. My advice would be to never use epoxy under a clear finish since it does poorly with UV as compared a high quality marine varnish such as Epifanes. The longest lasting varnish that we found is the Epifanes though there could be others the we have not tried. The most critical part of a long lasting varnish job are the initial base coats. Cut your first coat 50% with thinner, the second 25% to get good penetration into the wood for the best bond. Varnish in good conditions so that the varnish cures properly, don’t rush the overcoating. Finally, always add your maintenance coats before the varnish looks like it needs it. Once the crazing starts, you have waited too long and the varnish will never look as nice or hold up as well. We stripped the exterior mahogany on our 1953 Loki Yawl in 1999 and refinished with Epifanes. The varnish has been recoated with two coats per season when the boat was North in Maine and Nova Scotia and 2-3 times per year when used in the tropics. The varnish work on the boat still looked amazing in 2018 when we sold the boat. Best of luck.
Thanks very much guys
Yes I’ve been wondering whether to epoxy 1st or just the simpler direct varnish approach
All the very best

Same here with a 1982 Sharki. I sanded and cleaned it and varnished the area. First varnish was very diluted to move the varnish deep into the dry wood.
Might be done again after some time.
