and stick it on a roof rack
If you've got access to a roof rack capable of supporting about 350 pounds, why take it apart? Lash a couple of 2x8's to the driver and passenger sides of the rack, lash the mast to the trampoline, and enlist three "friends" to help set on top of the car. You'll need to position her far enough forward so the post protruding down below the front crossbar will not touch your windshield. So a little measuring is in order to determine how long the boards need to be, but I'm guessing eight or 10 foot.
Then it'll be at home where you can look at it. U-Haul or a hitch shop should be able to order a suitable hitch for your veeduble. If you purchase a catamaran trailer, your total weight with the boat will be about 750 lbs. or less.
If you want ot be feasible, order a hitch, find/buy a trailer and then go get your boat. But, I'm kind of like you, I doesn't present as much of a challenge to do it the easy way.
