I am familiar with these for shallow small boat use such as tarpon, etc. I am now faced with having to use the concept for larger boats in deeper water with real size anchor lines. What method/equipment should I use to allow very quick release to allow me to chase down bigger than usual Tuna? I will not know the length that I would normally need for a conventional anchoring so I envision some attachment that would grasp the line somehow to allow a float?? Those currently chunking know what I need.
