Twanger you will be fine. When I had Cuvée out on her maiden charter over NYE I was single handing her for the first 3 days until one of the charter guests asked if it would be helpful if he grabbed a mooring. They noticed that we were the only boat that had a guy walking from the helm to the bow to grab the painter to tie the boat up. None of them had any sailing experience, nor apparently any interest, so I was raising and unfurling sails and tacking alone (relying heavily on the autopilot). By the end of the ten days there were eager helpers for most tasks.
