Re: MC# lettering on PVC zodiac ?
You might get by on an inland lake or river with hanging a registration plate on your vessel, but they are not accepted by the USCG in coastal waters. Here in San Diego they will definitely hassle you for failing to properly mark your vessel. I used die cut letters and numbers as a stencil with a flexible paint available from Marine supply stores for use on inflatables.
"The following is an exerpt from an Official Newsletter distributed by the head of the Vessel Examination Dept of the USCG Auxiliary. STATE REGISTERED VESSELS -- The Requirements Are: Use of Block Style letters and numbers only; Letters & numbers must be at least Three (3) inches in height; Letters & numbers must be of Contrasting Color (not outlined, shadowed or rounded); if the background is multicolored or patterned, a block out area of a single color may be required to facilitate readability. The Letters and numbers must be separated by the width of one letter or number - not including the number one (1) or the capital letter (I). Use either a blank space or a hyphen and they must be read from left to right. The validation sticker must be visible and placed within six inches of the registration numbers. Placement either in front of or behind the numbers is determined by state regulation. The Registration Numbers, Letters and Sticker must be PERMANENTLY ATTACHED and on the Forward Half of the Vessel. Adhering registration numbers and stickers on glass or plastic windows or using placards (signboards) are NOT considered Permanent and can no longer be used unless they are bolted or screwed in place on the hull or superstructure (including on dinghies). Signboards cannot be attached to railings. Inflatable boat manufacturers should be contacted for letters and numbers made of the same material / adhesive as the boat to attain permanency. Validation stickers issued by states can be adhered to metal or plastic plates and mounted on grab straps with non-reversible wire ties, but must be within 6 inches of the registration number and visible to law enforcement officers. Contact your state for guidance and acceptability. Above reviewed by the United States Coast Guard office of Boating Safety on: 12/16/04 "
