I think the second response was tongue in cheek, but there is some buried wisdom in it. Are you buying new? Have you talked to any pond-side outfitters about ordering through them? Factory to dealer shipping is generally far more economical than trying to arrange it yourself. I can't imagine any 12' long kayak being unique or valuable enough to justify such an import burden. Venture (a UK manufactured line) makes excellent moderately priced kayaks if you are looking to buy new.
Actually, even if you are intent on arranging this yourself, you might be able to get information on cartage charges and import paperwork and duties from an outfitter -- they would be dealing with this on a regular basis and most don't mind sharing the information (I say this as one who used to work at outfitters).
