DEAD-RECKONING. n.s.

dead-reckoning-ns

DEAD-RECKONING. n.s. [a sea-term.] That estimation or
conjecture which the seamen make of the place where a ship
is, by keeping an account of her way by the log, by knowing
the course they have steered by the compass, and by rectifying
all with allowance for drift or lee-way; so that this reckon-
ing is without any observation of the sun, moon, and stars,
and is to be rectified as often as any good observation can be
had.
