What is the gizmo called that you mount on your forward boat trailer post that grabs your bow eye when the boat is driven onto the trailer? <br /><br />It's a big help for single handing the boat and being able to rely on the boat staying in place when driven onto the trailer, and the operator gets out to secure it. <br /><br />I've checked with Cableas and BassPro--no luck. But, I don't know the correct terminology.
