Fig. 7.—Hatch Coaming.

Hatch Coaming (see also page 459). Fig. 7—
(i) A—Coaming plating.

ai—Angle connecting coaming to deck plating.
dz—Deck beam.

aa—Vertical angles inside coaming to form a slot to receive the
end of the portable athwartship beam, they also stiffen
the plating.
at—A half round section on upper edge of coaming.

It will be noticed that the end of the half beams are connected
to the lower edge of the coaming in conformity with modern practice.
Formerly, however, the ends of half beams were connected to an
independent fore and aft vertical plate called a "carling" which
extended the length of the hatchway. A plate similar to a hatch
carling may be fitted to secure the inner end of a half beam when cut
in the way of a mast coaming. These fore and aft vertical plates are
then called the mast "partners."
