alt=Shipbuilding.png|thumb|Shipbuilding Shipbuilding is the construction of ships and other floating vessels. In modern times, it normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history.

On some sailboats, it may have a hydrodynamic and counterbalancing purpose as well. The laying of the keel is often the initial step in constructing a ship. In the British and American shipbuilding traditions, this event marks the beginning date of a ship's construction.

A skeg (or skegg or skag) is a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line. The term also applies to the lowest point on an outboard motor or the outdrive of an inboard/outboard. In more recent years, the name has been used for a fin on a surfboard which improves directional stability and to a movable fin on a kayak which adjusts the boat's centre of lateral resistance (it moves the center of resistance relative to the center of effort). The term is also often used for the fin on water skis in the U.S. It has been used for the vertical fin

SolidSail, sometimes referred to as Solid Sail or SolidSail Mast Factory (SMAF) in reference to the eponymous subsidiary, is a wind propulsion technology designed for large vessels, developed by Chantiers de l'Atlantique in Saint-Nazaire, France. This innovative system is based on rigid sails made of composite materials and a tilting gaff rigging, enabling hybrid or primary wind propulsion for commercial and cruise ships. It is also the name of the subsidiary created by Chantiers de l'Atlantique in 2023.
