Creative idea, and it might work if we were tying up to docks or something after launch. But we just hop on the boat as it slides off the wheels, and we are on our way. I would probably damage the tramp with the spikes before I could get them off and stowed on the boat.
Same thing in reverse when we return -- sail right up to the ramp, shove the wheels under the boat and pull it out.
Our fleet has two sets of Cat Trax and both have been fitted with the long dolly handle that Cat Trax offers. This has made it much easier to get the wheels under the boats without having to get down on the slippery part of the ramp as much.
The handle also comes in handy for towing the boats back to our drysail area. We use a golf cart, and somebody sits on the back of the cart and holds onto the handle.
