Try it. Or rather, don't.
If the boat is heeling you will be hanging to one side, perhaps 15 feet from the boat, as you slowly loose the ability to breath. Maybe you will be in the water
too. Certainly of no value to the single
hander. You could tie a large sail bag to a spare halyard
in a blow to test this.
If you have enough slack to allow moving to the bow, when you move to the cabin
top there will be aplenty of slack in the halyard
to wrap around the spreaders in some manner of knot
. Most sailors have done this once.
If you don't leave enough slack when you step off the cabin
top and move to the bow it will take you off your feet.
It does nothing to keep you on the deck. It gives no lateral stability.
I tried this (I was writing an article and it had been suggested as a good idea for catamarans) in fair weather
and it was a disaster. When using handlines and tethers in rough weather
you pull UPWARDS to keep your feet on the deck (anytime I see someone pushing down on life lines I know I'm watching a lubber). Any tether pulling up is wrong.
