The tramp can stay mostly on the R21 for trailering, but all 3 beams are unbolted and removed when collapsing. So the front of the tramp is disengaged from the front beam( it's a bolt rope into a groove), and the rear is loosened and unhooked from the rear beam. The bitch is that the side lacing(1 side) needs to be substantially loosened as well to get the hulls far enough apart when reassembling to get the beam bolts started. So you don't have to completely thread the lacing, but you do have to fully tension both the side and rear lacing when the boat is put together. And this consumes over 45 minutes with 2 guys.
Realistically, if you can't find a place to at least keep the boat fully assembled on it's trailer, near water, neither the R21 or the S23 is gonna get sailed very often. They're just too much set up and tear down time for day sailing. It'll get old very fast. Again, with a buddy who knew the drill, the fastest we could get the Reynolds assembled from driving to the ramp, to sailing away, was 2 hrs. And we had quite a bit of practice.
