I have been armchair traveling in upstate New York lately, and I notice that at the U.S./Canada entry port of Rouses Point, New York, Lake Champlain sticks up into Canada a few miles. I’m aware that the U.S.-Canadian border is “the longest undefended border in the world”, but I found myself wondering whether you could row a boat into the U.S. or Canada without the Coast Guard noticing. The lake is only about a mile wide there–does the Coast Guard patrol back and forth, back and forth, along the imaginary boundary line, or do they have radar to spot any boaters crossing the line, or what? What do they do to you if you’re out for a Sunday sail and find yourself (oopsie!) over the line?
Also, do the Canadians have spotters on their side watching for American smugglers? Or are things considerably more relaxed than that?
Just wondering, not planning any trips or anything.
(The U.S. Coast Guard patrols Lake Champlain because it’s a “federal waterway”.)
