  2. Chine (boating) - Wikipedia

    en.wikipedia.org/wiki/Chine_(boating)

    A padded V-hull is a hull shape found on both pure race boats and standard recreational craft. A variation of the more common V-hull , which has a V-section throughout the length of the vessel, a padded V-hull has a V-section at the bows and the forward part of the keel which then segues into a flat area typically 0.15 metres (5.9 in) to 0.25 ...

  3. 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 ...

  4. Strength of ships - Wikipedia

    en.wikipedia.org/wiki/Strength_of_ships

    The moment of inertia (technically, second moment of area) of the hull section is calculated by finding the neutral or central axis of the beam and then totaling up the quantity = + for each section of plate or girder making up the hull, with being the moment of inertia of that section of material, being the width (horizontal dimension) of the ...

  5. Tumblehome - Wikipedia

    en.wikipedia.org/wiki/Tumblehome

    The house and stable also incorporate an extremely rare tumblehome design throughout. The exterior walls slant inward from the base to the top. Since the interior walls are straight, the transition takes place in the exterior windows and doors which are wider at the bottom than they are at the top.

  6. Deck (ship) - Wikipedia

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

    The deck serves as the lid to the complex box girder which can be identified as the hull. It resists tension , compression , and racking forces. The deck's scantling is usually the same as the topsides , or might be heavier if the deck is expected to carry heavier loads (for example a container ship ).

  7. Corrugated galvanised iron - Wikipedia

    en.wikipedia.org/wiki/Corrugated_galvanised_iron

    Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...

  8. 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 ...

  9. Ferrocement - Wikipedia

    en.wikipedia.org/wiki/Ferrocement

    Ferrocement or ferro-cement [1] is a system of construction using reinforced mortar [2] or plaster (lime or cement, sand, and water) applied over an "armature" of metal mesh, woven, expanded metal, or metal-fibers, and closely spaced thin steel rods such as rebar. The metal commonly used is iron or some type of steel, and the mesh is made with ...
