I think you need to read the following ::
HOW LONG IS THE CERTIFICATE OF DOCUMENTATION GOOD?
A Certificate of Documentation is valid for one year from the date of issue,
providing there are NO CHANGES other than a change of owner's address. The
Certificate must be renewed on an annual basis. Even though it is up to the
owner to assure the document does not expire, the Coast Guard will send a
Notice of Renewal to the managing owner approxiamately 45 days prior to
expiration. There is no fee for the yearly renewal. See the instruction
letter Renewal of Certificate of Documentation elsewhere at this site
regarding renewal procedures.

My boat was already documented when I bought her.

So was ours. But it still cost a bundle to chnage the owner name and get
a new documentation with the same number.


It was about $85 for us, but maybe it went up. Of course, this is a
"lifetime" payment, there is no annual fee. In MA, it means no annual
registration, so it saves money pretty soon.
