Installing USCG boat number

I need to install the USCG vessel number on my boat. As most probably know, it needs to be affixed in some permanent way such that tampering is detectable. Obviously that leaves a lot of room for interpretation and creativity.

I was just going to apply stick-on letters to my engine stringer, then essentially paint over it with a few coats of epoxy.

Good idea? Bad idea?

Greetings,
Mr. tt. In MY opinion, that would be acceptable. We have our #'s on a 12"X12" sticker affixed to the hull in the ER which is coated with a layer of cloth and clear polyester. Any attempt to remove same or alter information would be readily detectable.

I have used the fiberglass cloth plus polyester coating method over stick on letters. Works well and is permanent.

stick on number with some sort of clear coat is what I used and CG inspection was OK. I don't remember what clear coat I used but make sure it wont mess up the vinyl letters

They accept carved letters on a screw on plaque...hard to believe they won't accept almost anything on a rec boat.

Yup, that's what I have with some glue on the back. Removal would leave a big mark - complies.

Ditto, but no screws.

You can simply paint the number in place and cover with thin glass cloth epoxied on top.

Cloth in clear resin becomes very clear so its good >forever<.

I also have mine this way, but the previous owner just used the stick on numbers (which is also still in place).

Lot's of you (maybe all) have used glass, then resin. Thoughts on leaving out the glass and just painting over with resin?

Also, a number of you have used polyester resin. I was thinking epoxy. Any objections to epoxy?

Much of this, quite frankly, is based on not having any materials other than the stickon letters. Whatever I buy, I'll likely have a lot left over so would like to use something that will be useful down the road. That's what leads me to epoxy, but I know very little about this aspects of boat construction.

Thanks for all the help and suggestions.

I'm sure that would be fine. As you see just about anything will meet the requirement.

Greetings,
Mr. tt. I used polyester simply because it's what I had immediately at hand and it set up very quickly. One can surely use epoxy as well. As far as the cloth, again, what I had immediately at hand. I think you can buy a small auto repair kit at auto zone or similar, even wally mart I expect, which includes both the cloth and the polyester resin.

IF you go with epoxy, make sure you buy epoxy compatible cloth IF you decide to use the cloth.

If you go the plaque approach you need to glue / epoxy it on instead of or in addition to screws. Screws OK to hold in place while glue / epoxy cures but they do not satisfy the "permanent" requirement if used alone.

Epoxy all by itself would certainly do it. No way to alter the numbers through the epoxy without being very obvious.

Please tell me of someone who has had that problem.

I would love to converse with them and backtrack to the USCG unit that cited them.

PS-In over thirty years, I have heard of one person being cited and that was for the numbers being too small (need to be 3" high). He had a metal plate, not too much bigger than a dog tag. The standards are so simple, permanently affixed and apparent damage if it was removed, it is hard to imagine anybody screwing it up.

Exactly my point..one can argue screw holes are damage just like scraping numbers off...

The rule is poorly worded..and easily fixed..therefore I would guess that if notvreworded...they must not care a lot.

Exactly. Heck, maybe disappearing ink might be arguable.
