There is no maintance fee to the federal government. Self documentation or undocumentation is easy and all of the instructions are on line. You can pay some one to do these for you if you wish--but it is not at all necessary.
Many states do require stickers (but not the state number) to allow the water or tax police to know that you have paid the state their due. For example a 16 to 26 foot boat in Florida costs about $22 a year in registration fees. There are a few cases where taxes may be avoided, but they are few. The documented status is slightly more secure than some states titles. A lien search as well as a chain of ownership search is easily preformed on a documented vessel.
There used to be some advantages, like the boat could be taken by the defense department and used for sub partrols during war time, or the marines could be sent to reclaim the US vessel. It is actually a little easier checking in and out of foreign ports with a documented vessel--just because the officials are used to working with a document, than a state registration. I would not carry my title aboard--but you are required to have the document aboard. I have documented the vast majority of my vessels--if nothing else to get away from the numbers on the bow. However the Tom Cat 255 came with numbers--and I have not yet transfered it to document status (the factory didn't send the correct information--and I suspect that they had not done a builders certificate previously).
