I am in the process of making three 'stitch 'n glue' kayaks. These are beautiful boats (and light). All three will be about 60 lbs. total. Anyone out there have any ideas about how to secure these to the roof of the PUP without wrecking anything? I don't want to buy an elaborate (and expensive) carrier. I'd prefer ideas on how to build something. My initial thought is to place a couple of boards with wedges to seat the boats in across the front and rear of the pup and strap them into place using the frame somehow. Then secure the kayaks to these boards. Somebody out there must have built something like this for carrying kayaks or canoes.
