Of course I'm not world class sailor so anything I say is rubbish according to some people. However, I have a knot in the adjustable line that blocks the system from giving more way than to the lowest position I ever want to be. So I won't fall in the drink and I can always find to lowest position quickly. I only use the adjustability to hang higher to come and go out or to clear the waves or hang higher than my crew so I can see what is going on ahead.
