One lash for asking a silly question.

Its not a "silly question," its a trick question, which can't be answered
with
one more piece of information. The key is that every sailor should know
the
Establishment (or Lunitidal Interval) for their home port, and others they
frequent. Do you know yours?


I'm not sure that there is only one piece of information missing!!


All I need to know is that when there is a full, or new, moon the HW will be
around 13:00.
