dead low water

A boat would just float there comfortably I supposed, at dead low water.

It was dead low water now, and the ship was heeled at an angle, the propeller showing clean.

Its utmost fury being felt about dead low water, less damage was sustained by the wharves and stores than might otherwise have been expected, but several shallops and small craft were sunk, and many others wrecked and torn by the sea.

May 30th.—The river Pei-ho is about 150 yards wide at its mouth, and at dead low water varies from 1 1⁄2 to 4 1⁄2 fathoms in depth.

The ship continued to fall over to starboard; at dead low water her inclination was 35°; the water covered the starboard gunwale from the mainmast aft, and reached almost up to the after hatchway; at this time the slightest shake must have caused her to fall over upon her side, when she would have instantly filled and sunk.
