As a matter of pride I will refinish the teak on my 25 before selling it. I just have to finish my engine projects, install a new winch, and clutches on my Ericson first. I forgot, stern perch seats too. So when the weather gets warmer I have to remove the Bristol finish from my teak. It's really crappy stuff and I how none of you has ever suffered from this product. Wanna know how I really feel about it? I'll try strippers, heat and sanding of course but I really want to leave a good surface for the next owner. I have had really good success with the new Cetol Natural on my Ericson so that's what I'll replace it with. When I sold my C-22 I had everything ready to go, and the new owner, an inexperienced guy, really appreciated it. It's a matter of pride thing as most of you share too.
It's also a very good way to get your boat to sell! I've sold three boats, each one amazingly quickly to people who marveled at how "nice" they looked, especially compared to the others they had looked at. I marvel, in turn, at sellers who can't even clear out the cabins or clean leaves out of the cockpits for photos.
Sorry--no help on the finish... Happily, I've never used varnish on the exterior! Cetol rules!
I have unfortunately had to refinish marine varnish way too many times. As the Cat25 has relatively little wood, I would remove the handrails and take them along with the hatch boards to a furniture stripper, tell them they will be refinished (that way they will bleach out any color imperfections) and then either varnish or oil (I would oil). If you varnish use Interlux clear sealer -- it dries in 15-30 minutes, you can put 5-8 coats on THEN use a good varnish as the top coat. Again, I would just oil the wood and re-installI have unfortunately had to refinish marine varnish way too many times.

Taking this course of action may seem expensive and/or time ocnsuming, but believe me it will be cheaper and faster long-run than dinking around with removers/strippers/solvents on the boat.
Frank, My boat originally had varnish on it and I tried sanding it off but it was extremely labor intensive and removed much more of the wood then I liked. I used a brush on stripper and it was much easier and spared the wood. A light sanding afterward removed whatever was left. I finished it off with light Cetol and it has held up well. This was done with the trim off the boat.
