My wife and I have sailed by ourselves and have not had any problems with our cat. Big difference though is we have a single line already attached to both cleats, in the very center of the line we have a loop reinforced with a metal ring and locking clasp. Once we nab the mooring ball, you can quickly thread the loop through the mooring and secure it with the locking clasp. Bottom line, like Stoney said, It's easy for just two people. Now, anyone know how to secure a cat single handled? Or has anyone even tried? As long as the mooring field is NOT crowded and there is NO wind I'd think it could be done with lots of pratice
