Canadian US cruising Documented or not does not matter, see below...and all foreign vessels transiting between Customs Ports require a cruising permit and a call in to customs to report vessel movement. The term "undocumented" below refers to US documented vessels. It is not necessary to have or report a US address in order to State register your vessel if a foreign owner, again, personal experience.. I have a neighbour who purchased a pleasure craft in Ft Myers 3 months ago, he State registered the boat in Florida, he is supposed to get a cruising permit if intending to cruise outside the Ft Myers customs jurisdiction according to the Customs officer in Ft Myers, his vessel is classed as a foreign vessel. Marmot, what is not clear about the following... The Customs Regulations provide under section 4.3, footnote 9 (19 CFR 4.3 n. 9) that, "Every undocumented vessel of 5 net tons or over owned by an alien, whether or not such alien is a resident of the United States is a foreign vessel".
