A multihull is a boat or ship with more than one hull, whereas a vessel with a single hull is a monohull. The most common multihulls are catamarans, and trimarans. There are other types, with four or more hulls, but such examples are very rare and tend to be specialised for particular functions.
Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. Naval architecture involves basic and applied research, design, development, design evaluation (classification) and calculations during all stages of the life of a marine vehicle. Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Ship design calculations are also required for ships being modified. Naval architecture also involves formulation of safety regulations and damage-control rules and the approval and certification of ship designs to meet statutory and non-statutory requirements.
Ulstein is a municipality in Møre og Romsdal county, Norway. It is part of the Sunnmøre region. The commercial and administrative centre of Ulstein is the town of Ulsteinvik. The municipality occupies the western half of the island of Hareidlandet, as well as about 30 smaller islands, four of which are populated.
A shipyard, also called a dockyard or boatyard, is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Compared to shipyards, which are sometimes more involved with original construction, dockyards are sometimes more linked with maintenance and basing activities. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.
Anchor Handling Tug Supply (AHTS) vessels are mainly built to handle anchors for oil rigs, tow them to location, and use them to secure the rigs in place. AHTS vessels sometimes also serve as Emergency Response and Rescue Vessels (ERRVs) and as supply transports.

The bow is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern.
USS Sumter (LST-1181) was the third of twenty Newport-class tank landing ships in service with the United States Navy, which replaced the traditional bow door-design tank landing ships (LSTs). Sumter was constructed by Philadelphia Naval Shipyard in Philadelphia, Pennsylvania and was launched in 1969. The ship entered service in 1970, was assigned to the Pacific coast of the United States and deployed to the western Pacific twice during the Vietnam War. In 1973, Sumter was reassigned to the Atlantic coast and took part in operations in along the Eastern Seaboard of the United States, the Mediterranean Sea and the Caribbean Sea. The LST was decommissioned in 1993.
Sigmund Borgundvåg is a Norwegian naval architect of offshore vessels including platform supply ships and deep-sea tugs.
A wave-piercing boat hull has a very fine bow, with reduced buoyancy in the forward portions. When a wave is encountered, the lack of buoyancy means the hull pierces through the water rather than riding over the top, resulting in a smoother ride than traditional designs, and in diminished mechanical stress on the vessel. It also reduces a boat's wave-making resistance.
USS Peoria (LST-1183) was a Newport-class tank landing ship which replaced the traditional bow door-design tank landing ships (LSTs). The vessel took part in the Vietnam War and Gulf War. The ship was constructed by the National Steel and Shipbuilding Company in San Diego, California and was launched in 1968 and commissioned in 1970. Named for a city in Illinois, Peoria was assigned to the United States Pacific Fleet and home ported at San Diego. The tank landing ship alternated between military exercises along the United States west coast and deployments to the western Pacific. Peoria took part in the evacuations of Phnom Penh, Cambodia and Saigon, South Vietnam, both of which signaled the end of American involvement in the respective countries. The vessel was decommissioned 1994 and sunk as a target ship during a RIMPAC naval exercise in 2004.
A sailing yacht, is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least 33 feet (10 m) in length and have been judged to have good aesthetic qualities. Sailboats that do not accommodate overnight use or are smaller than 30 feet (9.1 m) are not universally called yachts. Sailing yachts in excess of 130 feet (40 m) are generally considered to be superyachts.
GC Rieber Shipping is a Norwegian shipping company that operates offshore subsea support vessels, marine seismic vessels and polar logistics and research expeditions. Based in Bergen, Norway it is listed on the Oslo Stock Exchange. A major owner is GC Rieber.
MS Nordkapp is a Hurtigruten ship built in 1996 by Kleven Verft AS, Norway, for Ofotens og Vesteraalens Dampskibsselskab for use in Hurtigruten ferry service along the coast of Norway. She is a sister ship of MS Polarlys and MS Nordnorge. Nordkapp is one of 11 ships that travel the Norwegian coast from Bergen to Kirkenes.
In ship design, an inverted bow is a ship's or large boat's bow whose farthest forward point is not at the top. The result may somewhat resemble a submarine's bow. Inverted bows maximize the length of waterline and hence the hull speed, and have often better hydrodynamic drag than ordinary bows. On the other hand, they have very little reserve buoyancy and tend to dive under waves instead of piercing or going over them.
Kleven Group is the parent company for Kleven shipyard and Myklebust shipyard, and is one of the largest companies in Ulsteinvik besides Rolls-Royce Marine and Ulstein Group. Kleven Group had about 450 employees in 2011.
Gemini is a 600 megawatt (MW) offshore wind farm off the coast of the Netherlands. Construction started in 2015 with final commissioning in 2017. At the time of completion it was the second largest offshore wind farm on Earth after the London Array.
