We all know Valley's toggle system with bungee and a hook. On a few occasions I have seen the hook catch the other boats lines, during a rescue. Obviously this is not very good - at all.! The hook has also slipped off, while I was pulling the boat on land, resulting in serious pain from the finger that got hit. Strangely it tends to hit the exact same spot more than once....

That there is quite a few issues regarding toggles and safety, it does matter how you alter/make these things. Gnarlydog has a couple of good points on this subject.

This is not at all my own idea - once more, stolen from Gnarlydog :-)
