Here's some pics of a canoe with my rack setup. I have a drill holes in the roof Yakima (EV Nuts type, I take no credit, I took his idea) and then some quick metal things I welded up for the front and rear tow hitches. Held the boat fine and no paint/rope rub on the bumpers. I enjoyed being able to remove everything as I rented the canoe up there (Wyoming, Grand Teton NP) so that the 2000+ mile drive was without roofrack (yakima and welded things were inside the car). I did drive 200 miles in a weekend with two kayaks on top with this setup, held them solid.
