Bob, who moors a couple of boats along from us, passed on a trick he'd learned from another boater -reportedly an elderly lady single hander.
Picture this. You bring your boat in alongside some sheet piling and want to quickly tie up. Maybe there are passing boats which are pulling your boat around as they pass. Time is of the essence. What you need to so is to tie off one end of the boat very quickly, then run up to the other end to secure that. Well here's the trick.
Today I made up a rope like this.
Just a short length with a loop on each end. Don't look too closely at my splicing, I'm not sure it's quite right, but it is strong.
One end drops over the dolly at the back of the boat, the other end goes through your piling clip or chain which has been dropped through the piling beam, then back over the dolly. This should be quicker than having to tie off with a knot at the dolly. Then you nip up to the front of the boat and tie off there in the normal way pulling the boat forward so as to tighten the short rope at the rear.
I'm not sure what is the ideal length of rope, at six feet mine will give a reach of three feet from dolly to clip. I think that'll be about right in most places.
Well I haven't tried it yet of course but that's the theory. Bob says it works for him.
I'd be interested to hear if anyone else has tried this.
