Apparently, it's an acronym which stands for:
P - port
O - outbound
S - starboard
H - homebound
in reference to which side of the boat the sun shone on on cross-Atlantic voyages (Europe to America). Supposedly, the wealthy folks who cruised alot would forget whether they were coming or going, and this acronym helped them remember.
completely pointless info, I know....
