SEA
Puts your prompt mode on a ship instead of on an island.
This command is the opposite of the LAND command and is used
to gain access to all of the "Sea only" commands. When going to
land you must select an island. When going to sea you must select
a ship number. Certain sea commands effect the current ship only
(e.g. SAIL, RADAR, VIEW).
SEA [<shipnum>]
Where: <shipnum> = Is the number of the ship you wish to
operate from.
