Granted an 80 pound canoe (17'2" Old Town Tripper) is heavier than most of those yaks but this is how we used to roll. Y'all might laugh but a minivan is an outstanding canoe/yak carrier. Lower to the ground than a truck (easier for a woman to help load) and yet has a nice long roof.
1997 Grand Caravan (no longer have it)
1988 F-150 (still runs like a champ)
