Maybe possible, but a trailer, or an old beat-up Volvo, would seem to me to be a much better idea.
I was getting out of my boat at Brown's Bridge on Rocky Gorge one day, while another boater was getting ready to launch his aluminum fishing boat. If you've ever been to Brown's Bridge, its a bit tricky to launch at with a trailer...... its maybe 1/8 of a mile down a fairly steep hill to the water, with room enough for two cars to pass if you're really careful, but not much hope of turning around a trailer rig, you either back in or back out.
The fishing feller had succeeded in backing in, and when he saw me getting out he inched over to the side so I could pull down in if I wanted to. We said howdy, he said he'd be a bit untying his boat, that I should go ahead, I said no, I'm just chillin', you go ahead. While we were working out who was going first, how's the fishing lately, etc.... this little car pulling a kayak trailer came flying by the both of us, heading down into the lake. He was having a bad day or something, was probably doing 30 when he passed us, I can't believe he got stopped without running into the lake. I looked at my newfound fishin' buddy and said 'Man, stay out of that guy's way, he owns this here lake'. He laughed, and said 'Yeah, but now he's got to back that rig out of here, and I'm not going to be too quick getting out of his way!'.
In the end, he had the last laugh, though. He hopped out, unclipped the trailer, maneuvered it around like a wheelbarrow to launch the boats (3 of them), turned the car around, clipped the trailer back on, and blew right by us again going uphill...... all in probably less time than it takes to read this.
Get a kayak trailer.
