I must really be lazier than I already knew I was.



I have a Nacra 6.0, before that, Prindle 18-2. Both have symmetrical hulls. (As does most boats these days).



I find a 12" diameter PVC pipe at a construction site for free. Use a jig saw, and cut it into the shape of a cradle, it's easy.

If using them on your wheels, line up the axle holes, drill and use a stove bolt head(flat).

Contact cement some good carpet to it (friends a carpet layer, I only use the good stuff).

Get creative and use a similar/ strong/ easy method to attach them to your trailer.



These are much stronger than the commercially available types, almost free, and work forever. For my Nacra 6.0 hull, the round shape of the 12" pipe works very snug.



For an I-20(fatter hulls), you'd probably need at least 15"diameter. Just place a cut piece against the hull as a template.



Just some more ideas, and what works for me, without any glassing.
