How to anchor with "stern-tie" single handed
I'm getting ready to go into an area (Desolation Sound, British Columbia) that apparently often requires a "stern-tie" anchoring setup. This is used in very narrow anchorages that do not have room to swing. The idea is you have normal anchor out but then a line strung from the boat's stern to something on shore (tree, rock, whatever) to prevent swinging.
I've never done this before. And everything I've read explaining it involves 2 people, one staying on-board to keep the boat in position and another going ashore to run the line. Well I'm solo this trip, and I can't figure out a way to do this by myself. Hoping somebody with experience can give advice or tell me to just not go places where this is required. Thanks.
