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 jib is a triangular sail that sets ahead of the foremast of a sailing vessel. Its forward corner (tack) is fixed to the bowsprit, to the bows, or to the deck between the bowsprit and the foremost mast. Jibs and spinnakers are the two main types of headsails on a modern boat.

thumb Hawsehole is a nautical term for a small hole in the hull of a ship through which hawsers may be passed. It is also known as a cat hole. In the (British) Royal Navy, a man who had risen from the lowest grade to officer was said to have "come in at the hawsehole".

The portmanteau stands for "Mehrzweck-Kombination" (English: multi-purpose-combination). It is a concept in modern naval shipbuilding based on modularity of armament, electronics and other equipment, aiming at ease of maintenance and cost reduction.
