Anchored Gunnery
Arcs
An anchored arc-of-fire has one edge aligned with the
fore-aft line of the firing vessel, with the apex of the arc centered on the
forward funnel of the ship model. The adjoining edge indicates the termination
of the arc. In the figure at left, the 135 degree arc is shown anchored off of
the bow of the example vessel. If anchored off of the stern, the arc would be
swung 45 degrees clockwise in order to align its "rear" edge with that part of
the vessel aft of the forward funnel. |

Centered Gunnery
Arcs
A centered arc-of-fire has its center-line aligned parallel
or perpendicular to the major axes of the vessel, with the apex of the arc
centered on the forward funnel of the ship model. In the figure at left is
shown a 135 degree arc centered on the starboard beam of the example vessel. If
centered on the bow, the arc would be swung 90 degrees counter-clockwise in
order to align its center-line with the vessel's bow/stern axis. |

Center-line Mounted
Torpedo Arcs
Torpedo positions mounted on the center-line of a
vessel have a 95 degree arc-of-fire. In the figure at left is shown the 95°
arc centered on the starboard beam of the example vessel. The notch on the end
of the 95° arc is to ease handling and has no angle function. |
 |
Side/End Mounted
Torpedo Arcs
Torpedo positions mounted in the beam, stem or
stern of a vessel have a 60 degree arc-of-fire. In the figure at left is shown
a 150 degree arc anchored on the port beam of the example vessel in a way that
leaves an angled portion projecting off of the starboard side. The resulting 30
degree angle described by the arc defines half of the starboard side's
available torpedo arc-of-fire.
Note that this same method can be used
to establish whether a vessel has enemy ships within its front or rear
positional arc noted in the rules introduction page. |
