CaptainMike:

This is just my opinion, but I wouldn't coat the hatch covers with Cetol or any impervious finish. The reason is that they're inevitably going to get knicked and scratched, and they're going to take a lot of direct sunlight. I'd finish them with a coat of natural oil-based teak stain, then a coat of teak oil.

Depending on how much sunlight and wear they get, you might have to recoat them once or twice in the season, but that's literally a ten minute job. Use the Cetol on all other wood surfaces that are not going to be underfoot or getting banged regularly. A single surface penetration will begin to ruin any impervious finish, whereas oil and stain will just gradually wear off.
