Not much of a sailor on the cruiser. According to TFA he saw the sub 100-200 yds ahead and ordered "all back". Should have been hard a port or starboard
If he saw the sail of the sub 100-200 yds ahead then the submerged stern of the submarine was 40-140 yds ahead. There wasn't enough time to turn.
An Ada exception is when a routine gets in trouble and says 'Beam me up, Scotty'.
