Bilge: the underwater part of a ship between the flat of the bottom and the vertical topsides [13] Bottom: the lowest part of the ship's hull. Bow: front of a ship (opposite of "stern") [1] Centerline or centreline: an imaginary, central line drawn from the bow to the stern. [1] Fore or forward: at or toward the front of a ship or further ahead ...
Diagram contrasting course made good to windward by tacking a schooner versus a square-rigged ship. Sailing vessels cannot sail directly into the wind. Instead, square-riggers must sail a course that is between 60° and 70° away from the wind direction [76] and fore-and aft vessels can typically sail no closer than 45°. [77]
Among sailing craft, the windward vessel is normally the more maneuverable. For this reason, rule 12 of the International Regulations for Preventing Collisions at Sea, applying to sailing vessels, stipulates that where two are sailing in similar directions in relation to the wind, the windward vessel gives way to the leeward vessel.

A. Into the wind; shaded: "no-go zone" where a craft may be "in irons". A point of sail is a sailing craft's direction of travel under sail in relation to the true wind direction over the surface. The principal points of sail roughly correspond to 45° segments of a circle, starting with 0° directly into the wind.
Sailing Directions are written directions that describe the routes to be taken by boats and ships during coastal navigation and port approaches. There are also products known as Sailing Directions, which are books written by various Hydrographic Offices throughout the world. They are known as Pilot Books, because they provide local knowledge of ...
Sailing employs the wind—acting on sails, wingsails or kites —to propel a craft on the surface of the water (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ice (iceboat) or on land (land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century ...
Tacking: Sailing the craft into the wind from the port tack to the starboard tack. Beating to windward on a series of port and starboard tacks, tacking between each at points 1, 2, and 3. Tacking or coming about is a sailing maneuver by which a sailing craft (sailing vessel, ice boat, or land yacht), whose next destination is into the wind ...
The port and starboard sides of the vessel always refer to the same portion of the vessel's structure, and do not depend on the position of someone aboard the vessel. The port side is the side to the left of an observer aboard the vessel and facing the bow, towards the direction the vessel is heading when underway in the forward direction. The ...
