  2. Boat building - Wikipedia

    en.wikipedia.org/wiki/Boat_building

    A subdivision of the sheet plywood boat building method is known as the stitch-and-glue method, [8] where pre-shaped panels of plywood are drawn together then edge glued and reinforced with fibreglass without the use of a frame. [9] Metal or plastic ties, nylon fishing line or copper wires pull curved flat panels into three-dimensional curved ...

  3. Strength of ships - Wikipedia

    en.wikipedia.org/wiki/Strength_of_ships

    The strength of ships is a topic of key interest to naval architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built too weakly suffer from minor hull damage and in some extreme cases catastrophic failure and sinking.

  4. 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. The line where the hull meets the water surface is called the waterline.

    en.wikipedia.org/wiki/Deck_(ship)

    The process for building a deck in fiberglass is the same as for building a hull: a female mould is built, a layer of gel coat is sprayed in, then layers of fiberglass in resin are built up to the required deck thickness (if the deck has a core, the outer skin layers of fiberglass and resin are laid, then the core material, and finally the ...

  6. Frame (nautical) - Wikipedia

    en.wikipedia.org/wiki/Frame_(nautical)

    Frames support the hull and give the ship its shape and strength. In wooden shipbuilding, each frame is composed of several sections, so that the grain of the wood can follow the curve of the frame. Starting from the keel, these are the floor (which crosses the keel and joins the frame to the keel), the first futtock , the second futtock , the ...

  7. Bulkhead (partition) - Wikipedia

    en.wikipedia.org/wiki/Bulkhead_(partition)

    Bulkheads were known to the ancient Greeks, who employed bulkheads in triremes to support the back of rams. By the Athenian trireme era (500 BC), [1] the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull with ...

  8. Girder - Wikipedia

    en.wikipedia.org/wiki/Girder

    A girder (/ ˈ ɡ ɜːr d ər /) is a beam used in construction. [1] It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web , but may also have a box shape, Z shape, or other forms.

  9. Strongback (girder) - Wikipedia

    en.wikipedia.org/wiki/Strongback_(girder)

    A strongback is a beam or girder which acts as a secondary support member to an existing structure. A strongback in a staircase is usually ordinary two-by dimensional lumber attached to the staircase stringers to stiffen the assembly.
