7. Reverse Pull: Sometimes the warp is simply snagged on your rudder, lower unit, transducer or whatever. "Fish" for the warp with a boathook or gaff. If you can grab it, bring it forward and place the warp in a bow chock or anchor roller and pull back toward the stern. Under the boat, the pull on the line will be toward the bow, which, it is hoped, will pull the warp out the way it went in.
