2. Double hull - Wikipedia

   en.wikipedia.org/wiki/Double_hull

   Single hull, Double bottom, and Double hull ship cross sections. Green lines are watertight; black structure is not watertight. A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard ...

3. Boat building - Wikipedia

   en.wikipedia.org/wiki/Boat_building

   Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.

4. Small-waterplane-area twin hull - Wikipedia

   en.wikipedia.org/.../Small-waterplane-area_twin_hull

   A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea , where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds.

5. Hull (watercraft) - Wikipedia

   en.wikipedia.org/wiki/Hull_(watercraft)

   A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy ), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures , such as a funnel, derrick, or mast .

6. Shipbuilding - Wikipedia

   en.wikipedia.org/wiki/Shipbuilding

   It was the keel that determined the shape and the structure of the hull of Fuchuan Ships. The keel is the middle of the bottom of the hull, constructed by connecting three sections; stern keel, main keel and poop keel. The hull spreads in the arc towards both sides forming the keel. [63] The helm was the device that controls direction when ...

7. Clinker (boat building) - Wikipedia

   en.wikipedia.org/wiki/Clinker_(boat_building)

   The Nydam boat, an early example of clinker construction. The earliest example of ship and boat building using overlapped planking joined with metal fastenings is in an extended logboat from Björke in Sweden. This dates to c. 310 AD. The Nydam boat is an almost complete example of a boat built with clinker construction. It has overlapping ...

8. Naval architecture - Wikipedia

   en.wikipedia.org/wiki/Naval_architecture

   Reconstruction of a 19th-century naval architect's office, Aberdeen Maritime Museum General Course of Study leading to Naval Architecture degree 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 ...

9. Carvel (boat building) - Wikipedia

   en.wikipedia.org/wiki/Carvel_(boat_building)

   Carvel construction allows hull shape to be determined by design, whilst planking-first relies on the "eye" of the builder. Therefore fewer very highly skilled personnel are needed. [5]: 101 One of the transitional ships is the Yassi Ada ship (seventh century CE), which was
