b. Sailing. Sailing or operating a motor-powered
lifeboat should be left to the experienced hands aboard;
in their absence proceed with greatest care. In the
hands of unskilled operators, the lifeboat may broach
to and capsize in a matter of seconds. Even when sail-
ing under the direction of an expert, keep your eyes
open for an accidental jibe-the sudden shifting of the
boom from one side of the boat to the other. Jibes
have injured men seriously and thrown others over-
board. Don't rig sails when in doubt about the weather;
never attempt to sail or use power in heavy seas and
high winds; wait for calmer weather. Remember, the
duty of everyone aboard is to conserve strength to stay
afloat until rescued and not to promote exhaustion by
struggling with unknown and otherwise avoidable
44. HANDLING LIFEBOATS IN SURF. It is of little
value to be in a lifeboat if you do not know how to
handle one safely in surf. The following paragraphs
are devoted to this and apply to all lifeboats whether
under sail, oars, or motor driven.
a. Running before a breaking sea or surf. The one
great danger when running before a broken sea is
"broaching to." The utmost attention must be directed
against such a disaster. Broaching to is the sudden
swerving of a boat from her course onto her side and
into the trough of a sea.
b. Action of boat in running before a breaking sea;
safe passage. The motion of the boat and the sea
being in the same direction, the boat makes no resistance
to the sea but is carried before it. If running in bow
first the surf on overtaking her will lift the stern and
bury the bow. If the boat has sufficient inertia (which
is proportional to weight) to allow the sea to pass her,
she will pass through the descending, the horizontal,
and the ascending positions in succession as the crest
of the wave passes beneath her stern, midships, and bow.
