It's probably been done but whether or not it was a success is hard to judge. The proof is in the paddling and there aren't that many boats of this type afloat at the moment.
Here's the problem you have to solve when contemplating a take-apart kayak. The keel of a kayak or any boat,for that that matter, has to be straight. If it isn't the boat will do neat tricks like constantly trying to make a right or left turn. In a human powered boat these kind of antics can get old in a hurry. If you cut a boat apart and can figure out how to make sure the pieces always line up when reassembled you've got it made. Also, your mating bulkheads have to be water tight so you can't punch any holes on them for connecting purposes.
With the struggles that I've had building paddle boats the thought of hacking a perfectly good hull apart fills me with horror.
No guts no glory ,I guess.

: take apart. Has anyone ever tried this (or seen it tried) with a strip
