The fire hose idea I like, and I know several firefighter/paramedics from the "werk-place."
As for my tied-down, I'm using a flat, nylon strap that I get at the hospital. They are normally used to strap people to backboards for spinal immobilization during transport. These straps are labeled for "one-time use ONLY."
Many come through clean and free of anything icky. They can't be used again for the original purpose, so they are free for the taking. I spend a lot of my time in the ER and quite often get left to get the patient off the board, myself. Not my job, but. . . My cost to them is I get to keep the straps!
The plastic buckles on these straps are their weak points. I don't use them, instead, I tie a bowline in the ends. One end gets looped to the inner rail, wrapped around the PVC cross bar, then over to one of the uprights and half-hitched around that. Then it goes over the boat and down the other side, following that same path. On this end, I add a piece of nylon rope to the end so I can tie it off, securely.
You can kind of see that, here:
From the side, you can see those straps going over the boat.
So, the orange straps hold the boat down on the cross bars, as well as side-to-side from the uprights. There is no lines going to the front bumper, as with the length of the boat and the design of the truck, such a line would run across the front of the hood, wearing into the paint. As far as I can tell, my current method does indeed hold the boat securely in place. It's made a number of trips that way, at highway speeds, and shown no tendency to move side to side, frontwards or backwards, nor up and down.
The base of the rack, 2 X 4's, fit into slots molded into the bedliner. The upper part of the rack is secured at 4 points, to steel hooks in the frame of the bed. The rack design is one I found here on the Forum somewhere.
Again, one of the nice things about it is that I can remove or mount the rack on the truck, by myself. And when off the truck, it makes a good storage stand for the Pirogue.
