We keep things simple and use the same method for each and every mooring ball for our catamaran trips. I am the "hooker", I give all the signals by hand, very seldom do I ever give a verbal cue. Once I hook the rope we have two people designated to tie off on the cleats, one port and one starboard. We seem to have it down pat pretty well, no one is yelling, no one is up on the bow looking or helping, everyone has a place and a job, even if your job is getting out of the way. The KISS method works pretty well and i cant remember the last time we had to try a second time.
