I’ve been gone from FL for awhile. But when we bought our boat there it was already USCG documented. If I remember, we could not get the new FL decals until the boat was properly redocumented b/c the Certificate of Documentation is essentially the “title” for the vessel. I know some things may have changed. Certainly with the documentation office they have. But I would be surprised if you could complete the FL registration w/o the Certificate (i.e., title).
Would you be cited if stopped w/o decals. The CG might well give you a pass on the documentation in progress. The Florida Marine Patrol, I don’t know. I would call them directly and ask. But, you might just get a mushy answer that’s not helpful. It ultimately comes down to what the two FMP officers decide on hearing your explanation. It’s a toss-up. I can imagine that they hear dozens of phony, or otherwise unacceptable, explanations every year as to why a vessel is lacking current decals, etc. But I see them as mostly working the power boat end of the enforcement spectrum.
