I have but it cost me close to, or the same, if I recall correctly, as a new documentation. Not big deal just send in your money and fill out the forms. Your documentation number does not change. MAnyone ever change their home port on a documented vessel? What forms and fees are required? What rules designate how you select your home port? I've seen people use their home town that is hundreds of miles from the ocean for instance.
Or the hailing port you chose, in this case Cumberland Foreside, ME, does not fit on the transom in the legal size letters, of the boat you just purchased..?? Doh'... Measure first document once....I can understand if you purchase a boat with a not too salty inland port but recognize that ito change the name would be a matter of vanity and not requirements.
