I am having to replace my bow winch on my bass tracker. The original winch has 2 hooks, 1 to the boat and the second to the trailer as a safety back up (I suppose). The winches I have looked up on amazon come with only the 1 hook, and unfortunately I cant get a "Hook" on a chain to fit into the ring on the bow of my boat. My question is - Is it necessary to have both the primary hook and a secondary hook to the trailer?
