My son bought me this Slip-Ring Mechanical anchor for my birthday. Last year I had no anchor at all, just kept forgetting to pick one up. I'm looking for a picture of how to rig this anchor up for use on my 17' bowrider. 2nd year boater here & don't know what to set it up with, do I need a chain attached to the slip-ring or just tie it up to a rope? Totally super newbi question, but I gotta ask. Thanks
