When you do register for documentation print out the form filled, confirmation number or whatever you can to carry with you until the final paperwork arrives. In addition you can go onto the USGC documentation page to print off your documentation information, once they’ve registered your boat but before you receive the final papers in the mail. This is what I’ve done so I can cruise ahead of receiving the final form. Renewals usually take 3 to 4 weeks. As Mike states, most states require your boat to be “state registered”. We have our state registration sticker on the side window but no hull numbers/letters as this is not needed with documentation.....as long as you follow the documentation guidelines.
