You are correct; that is an excellent method. Last year, I accomplished it with aluminum can shims. I was worried that slamming the frame on might harm the pylon shoe connection to the hulls. This stiffened it somewhat, although there was still some slop, but it was probably an appropriate amount. When the mast/rigging weight, etc., were added to the boat, it became clear that there was still some slop. I just desired a good connection between the joints.I will add that the epoxy stiffened it up little more over the shims, but you will have to decide whether you want to have to heat up the connection with a torch to get them apart if something has to be changed. Even with an epoxied frame, mast up but rig not tensioned, if I raise a hull while on the trailer, there is a 1-1/2"-2" departure before the second hull rises. Aluminum can shims were about 2-1/2-3" thick, and before any shims, around 4". I'm sure a tight tramp also plays a role in this tension.
