Generally,
this is a straightforward entry area, and it is easy to note, for
example, that a ship was wrecked on Start Point in Devon.
However, sooner or later it will be important to interrogate the
database for, say, ship losses in the Channel - requiring the
designation of sea (and/or command) areas. I have yet to find
definitions with suitable authority to provide a realistic solution.
In
the longer term, when collecting operational data, it may be
desirable to record ship latitude and longitude to tie ship
employment to specific operational commanders, sea areas and events.
