Coast Guard Documentation?
CG documentation is not required to "go foreign". It might make it a bit easier dealing with customs officers, however, who may never have heard of Delaware, much less Wilmington, or any other single state. (Who''s the Governor of Delaware, now, anyway? Will he answer the phone if the Republic of Podunk throws you in jail for entering with too many bottles of rum and try to help get you out? Probably not. ) Does your state registration form look like an official document, or something you could have picked up at Kinko''s? Customs officials all over the world are very likely to be familiar with the United States of America
and the documents it issues to its vessels, however. While some things aren''t required, sometimes common sense is a good idea.
