No problem; my old destroyer's maximum beam was 13 yards, so there was 
plenty of time to get across. The worst problem was trying to get a hundred 
sailors to run across the narrow space in the bow, stern and midships 
without elbowing each other in the ribs or knocking their friends down, 
accidently. I did mention "Chinese fire drill."

A proper martinet of a skipper would have his wife do the running back and 
forth while he did the supervising.
