Putting a boat on the roof of a vehicle is dumb: it really kills your fuel efficiency. You can get a small trailer to put the boat on instead, and then you can get a small car with a trailer hitch to pull it (if the boat is light enough to put on the roof of a minivan, it's probably a kayak and weighs very little), which means you don't need a big, ugly, gas-guzzling minivan or SUV at all. Any small car can pull a 500-pound utility trailer.

To each his own. I do know people who use trailers for sea kayaks and it can be quite a pain getting into tight quarters. So putting boats on the roof may be dumb but it's what 98% of the people I know with boats do.
