This is all good information. Couple other points - if it’s documented, you can NOT display state numbers, just the validation sticker. Some people think they’ll avoid L/E attention this way, when in fact it’s a writeable violation. Also, if it is currently documented, you’ll need (and very much WANT, for the reasons 1776 posted) a Letter of Deletion from USCG NMC. That is a very real thing for the owner per a current COD to be presumed the responsible party for pollution incidents. It takes a lot more than “oh, some dude named Bob gave me $1,000 for it, it’s his boat now.” Those numbers assigned on a state Certificate of Numbers? Required to be in 3” block Arabic font in a contrasting color affixed to forward half of vessel, where they are plainly visible, and the prefix and suffix spaced one character width not including “1” or “I”. I would guesstimate 50% of small recreational vessels (especially PWC’s) are non compliant. I think I’ve only seen that violation written once or twice in almost twenty years, but it is a violation. As far as the name of the boat, for a Certificate of Numbers (aka state registration), there is very little federal interest. The name does not appear on any state’s CON (informally: registration) that I’ve ever seen, and the Coast Guard uses (supposed to use) the state number as the vessel name in it’s own computer systems. And for the love of all things holy, keep the original registration onboard! It’s a regulatory requirement, and can be a hassle to verify - it takes much less work to write the violation then to warn it and deal with chasing it down in two different systems.
