How did you permanently mark USCG NO.

    I have a 350 Mariner, and thought it would be easy to permanently mark the USCG documentation number in the forward compartment where the anchor rode stows. Easy access and it would be right on the hull of the boat. But, I don't know if painting or attaching letters and "sealing" over them constitutes a "permanent" mark.

    What did the rest of you folks do?

    Thanks...

    Have the number router-ed into an approx 3/4" thick x 5" wide x 20" long piece of mahogany. Then bond it to a stringer in the engine room with resin and fiberglass matting.

    if you dont' have a router handy, you can use adhesive numbers and cover them with a layer of glass and resin... i usually put that in the anchor locker at the bow since wall space in most ER is usually too valuable!

    Thanks for the prompt replies! I would like to try the numbers on the hull idea. I didn't know if you could see through a layer of glass mat and resin well enough. Sounds like you can.

    Thanks again...

    Although it's supposed to be permanently affixed, I've seen it many times (and shown same to boarding officers) in stick-on #s. I think most people understand that there is no such thing as permanently affixed, although RER has it right. I usually find them (and recommend that people put them) visable when you open the engine hatch. The CG will be looking in there anyway. The alley side of the engine bed is usually a good spot.

    Rather than starting a new thread, I used the search tool and revived this one.
    I may be making a bigger deal of this than it warrants but I want to get this done and I want it to look shipshape and well, bristol comes to mind.
    I dremeled them into a wooden stringer on a sailboat, I have to still get them permanently affixed on my current boat. Why do I procrastinate on such a simple job?

    I find the USCG requirements pretty specific and I won't deviate.
    ...so that alteration, removal or replacement would be obvious. Painted, carved or welded.
    I am not artistic enough to Paint 3" Arabic letters and numerals, I may get the dremel out again. Maybe I will put the home depot stick on numbers and dremel around them as a template so that I have a better looking outcome after taking the stickers off.

    You could pick up a stencil at a craft shop, pencil it in and then Dremel that out or even paint it. I wouldn't recommend Dremeling stick-on letters as they'll tear off part way into your job. I've seen people simply use those stick-on letters and they got no complaints even though that's obviously not to code. With a commercial or certified vessel and maybe large private yachts they're sticklers, but for most recreational boats they're more concerned with how many PFDs you have when they inspect.

    You’re making this way too complicated. Clean the area with acetone. Put on the self stick numbers, put a coat of resin/hardener over it and call it good

    I know I am making it more complicated, that is why I resurrected this thread, I don’t want this to look like someone did what you are describing. Bristol is what I am stalling for.
    I get what you are saying, it is not a big deal for USCG as long as it is permanently affixed.

    Actually, I am adopting your idea about the craft store and stencil work, thank you.

    If this is on a sailboat and Bristol is what you're looking for make sure you find a nice piece of wood. Where you're at some nice redwood might be nice (or is that like oak here). My experience with sail boaters is they tend to fall into two groups, either messy or pristine with an eye for the details. Sounds like you're in the 2nd group.:D

    If you want something harder to remove or wear off, try using an engraver or etching tool and put it on something metal.

    I have two boats, one sail one power.
    I see what you see in the two sides of sailboaters, I see it with many older searays and the like too:D.
    Guilty as charged, my Father instilled the concept he called “pride of ownership”.

    And how do you permanently affixed that to a fiberglass boat??? Decals and a coat of resin is the only permanent way to affix the official registration to the boat.

    but I guess the poster can continue to operate his vessel illegally!

    Thanks Capt J. Pointing out my criminal activity was not what I had in mind, but you have busted me. Good thing my boat is on the hard right now, easiest place to operate illegally.
    Point taken.

    A marine Sign Shop in San Diego uses a local carpenter to make a wood plaque that has the numbers cut in with a router using templates. The numbers are 1/4" deep, painted black inside, and the plaque is attached to the stringer. I'm sure the method varies. but tabbing it on with glass cloth and resin would leave the most blemish if the thing was chipped off.
    The whole concept is rather absurd, because there is no defined location for the Doc numbers where it can easily be seen if they were destructively removed, or, in the case of clearcoated dingy numbers; simply painted over. Every time an inspection team has come aboard, I've had to direct them to the location of the "indelible" Doc number.
    Even HIN numbers are in a variety of places. Some vessels hide them in compartments, and, a hull extension really confounds it.

    I had a stencil made and spray painted on the side of the engine bed /stringer. I guess one could glass over to make more "permanent".

    So this is not the Hull ID?
