Hull down
In sailing and warfare, to be hull down means that the upper part of a vessel or vehicle is visible, but the main, lower body (hull) is not; the term hull up means that all of the body is visible. The terms originated with sailing and naval warfare in which the curvature of the Earth causes an approaching vessel to be first visible "sails up". Beginning in the 20th century, hull down has also been used in armoured warfare.
