If your boat is documented with the U.S. Coast Guard, the owner must designate a name, and it has to follow federal rules (46 CFR 67.117). It must be made of letters of the Latin alphabet or Arabic or Roman numerals. It can't be identical, actually or phonetically, to words used to call for help at sea, and it can't contain or sound like obscene, indecent or profane language or racial or ethnic slurs. Once documented, the name can't be changed without the National Vessel Documentation Center's prior approval.
For a boat documented only for recreation, the name and hailing port are marked together on some clearly visible exterior part of the hull (46 CFR 67.123). The letters must be durable, clearly legible and at least 4 inches high.
A name is your choice; a state registration number is not. Federal rules (33 CFR 173.27) put the number on each side of the forward half of the boat, in plain vertical block characters at least 3 inches high, in a color that contrasts with the hull, reading left to right. Keep the name clear of the number so both stay easy to read.
46 CFR 67.117 and 67.123 (vessel name and marking) and 33 CFR 173.27 (registration numbers).
