My father retired to the Oregon coast a few years ago and has since taken up crabbing. For father’s day I’m making him a crab gauge/caliper from cherry. It is used to measure dungeness crab by their shell’s, anything under 5 3/4” must be released from the pots. He is just a hobbyist but, I would like it to be as durable as possible. I was thinking of finishing with a little shellac and alot of poly. Would the poly hold up to the salinity? Or water for that matter? Suggestions for an alternative would be cool. I’m thinking it will be wet often but, not continually submerged.

Roughly shaped.

As Loren says Minwax has a Marine Spar Varnish (green quart can) sold at Lowe’s among other paint retailers. It’s specifically intended for wet use.

Make it teak and don’t put anything on it. It will last for about 100 years and have a lovely silver color.
No varnish, epoxy, oil or any other finish will last long without care in marine conditions.

I spent a few years at sea – - 25 years to be exact! The US navy uses Spar Varnish for these wooden details. I use MinWax Spar Varnish for all of my ‘sea worthy’ projects. Good luck.

Round one to spar. Thanks guy’s.
Loren.
I should have thought of that Ship. I spent alot of time on Lake Powell as a kid. Our SeaRay was trimmed in teak.
Someday when I go visit him, I will have to try my hand with the crab.

Can’t recall the brand name but Marine Grade Spar varnish, available in Marine (boating) shops. Its quite a bit more expensive than the stuff you see in Big Box stores.
