After several years of variations on the theme of the keystone cops I finally installed a tiller pilot and that surely made several operations smoother, safer and more sailorly looking for the assembled crowds. Single handing is great, but when things get tight a silent, obedient crew is wonderful.
A crew that know's you can do it better single handed than they can collectively will be quiet and obey. However, you must be quiet and calm when when directing them. The first sign of a captain that doesn't know what they are doing, is the tone they are using with their crew. The guy yell'n and blaming the crew, ought to be able to do any maneuver by himself. Therefore, he ought not be yell'n! And certainly should not be running the show.
