Teak upkeep

I am wondering about the logistics for maintaining teak trim. I am thinking of switching from varnish to oil, which requires removing and sanding off the current varnish. Do most of you do this with the boat in the water or do you take it out to do this? Do you need a certain amount of time with dry weather? I would love to hear your thoughts on this and any other considerations. I have a teak rub rail and companion way that I will be working on. Cheers!

I would remove everything that can be removed and take it home for refinishing. That said, for me, it would depend on how easily removed. I like exposed screw heads for easier maintenance. I would have to be exceptionally motivated to remove anything with screws hidden by bungs. It seems like a lot of work to sand off varnish to bare wood. Personally, I would avoid that by prepping for varnish recoat. Long term, I agree that oil would probably be the more satisfying finish. It's really a personal decision based on too many variables to generalize. It sounds like you are talking primarily about exterior brightwork. Most of the folks in our marina typically are busy with these tasks in the late spring with boat in the water, before the temps get too hot. I've seen mostly varnish and/of cetol. I don't notice any favoring oil. Obviously, the dryer the weather the better, but I don't notice anybody getting awfully concerned about doing the work in the spring when we have unsettled weather.

Cape Dorys in our area seem to get special attention from their owners. I notice quite a few that have beautiful brightwork. I think varnish is the most common treatment. Constant care and maintenance is the key.

In the past we’ve used Cetol and Semco, and always done all the work in the water. My preference is to leave the wood in place as the screws on ours were covered by bungs, and I wouldn’t want to disturb their bedding anyway. Like Scott said it’s a good project for spring days, especially days after cold fronts come through when it’s dry and sunny but too windy to go out sailing.

Calm mornings before 10AM on dry days are best. Waiting till the sun is at it’s peak will have the varnish solvents flashing off before it has the opportunity to level.

Varnish can be touched up. I prefer the satin finish to a high gloss.
