OK guys... thanks for the input. As I suspected, and as confirmed by a few of you, the four corners technique apparently works... I came home from work today, Tuesday, and my straps were already here. I got them off Amazon for about $2.25 each. I found some old webbing I had once used as a safety line under my hoisted canoes (had a hoist break once, and dropped one end of a wood canvas canoe 8' to the ground.) I cut this in half and got the black straps you'll see in the photos. I then cut all but 1' of the orange straps off those, doubled them up, sewed a box and an X, and I have success.
Here's one of the black straps larks headed to my thwart.
This then runs down the side to the orange strap/buckle, which is larks-headed to the cart frame.
like so...
All four corners done looks like this.
This is how I zip tied a spare clevis pin to the frame.
These are my hot pink clevis pins.
And this is how I used a tiny zip tie to close the retainer loop so it absolutely cannot fall off.
And here's the other end of it, secured the same way. You can see the original "clamp" in that black lump, but it makes too big a loop.
I am only slightly concerned that the canoe will still roll or yaw now... I was rough with it, stood it up on its nose with the cart attached, and it hardly moved... I MAY carry one of the Suspenz straps still, to throw over the middle and strap the canoe to the cart from yet another dimension, but it should hold with just the 4. I'll let you know.
