No doubt that they are cool, I seriously considered them.
The main reason I did not go with them is, they will be in and out of the water every time you head out for a ride. I did not want to out the mechanics of the ratchet system in the water that often. Once they fail, you will need to buy another set and the money would just keep adding up.
I have a center loop in the middle of my tandum trailer and then the normal loops/holes near the tail lights. I use quality ratchet straps, as a result the hooks do not fit through the loops on either of my skis. I use to have to pull the strap out of the ratchet and thread it through the loops of the ski then back into the ratchet.
I bought four (two per ski) carabiner clips that have sleeves that thread the clip closed for strength and leave them right on my straps. So now all you have to do is, loosen the strap, un-clip the carabiner clip, pull the hooks from the trailer and toss them into the back of my car. Installing is just as easy, pop the carabiner clips onto the skis, put the hooks into the loops and tighten the ratchet strap.
Works perfect and takes literally 30 seconds or so.
They look like this but are more heavy duty, (rated for 1000 pounds).
