Canada and the United States have the distinction of having the longest border in the world, officially known as the “International Boundary”. Of course, much of this boundary runs through water, namely in the Great Lakes region, and many boaters share common waters in many areas not only in this region, but from coast to coast. Cross border transactions of boat sales have been happening for many years, but with the change of economic times recently, there seems to have been a significant increase in cross border deals. - See more at: http://www.ybaa.com/aws/YBAA/pt/sd/news_article/81689/_PARENT/layout_details/false#sthash.bUzrp7Nv.dpuf
