Just make sure you have all the documents you need, as well as the exact amount you need to pay. They don't take cash, and they may not even take personal checks, but that info is all on their site.
i think i needed a money order made out to them wich costs at your local bank another fee
pain in the @ss the first time but i got busted once by the environmental popo and paid $ 150 cause i didnt register my old boat with an e trolly motor
personal check is fine. bring copies of everything you can. don't forget a pencil tracing of the Hull ID # and try to print a black and white picture of it if you can. i think they just took that from me. I'll let you know of any new hassles as i'll be making another trip to the boston office this week lol
