Came across a useful bit of kit the other week that makes keeping all your lines from flapping in the wind!
Its called the cable cuff and good for keeping tidy alll sorts of lines and extension cords. Made of strong lightweight plastic , they adjust to secure and then quick release. hey and they are orange too! My favorite colour.
Also dead cheap , which makes a nice change.
So especially good for all those "Knot challenged" who have trouble with even a half hitch
