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 top timber , and the rail stanchion . [ 1 ]
Sheet plywood boat building uses sheets of plywood panels usually fixed to longitudinal long wood such the chines, inwhales (sheer clamps) or intermediate stringers which are all bent around a series of frames. By attaching the ply sheets to the longwood rather than directly to the frames this avoids hard spots or an unfair hull.
Frame-first construction involves laying down the framework of the vessel before attaching the planks to the boat. This is normally done by erecting a "master frame" in the center of the keel, and deriving the shapes of the other frames using a curved piece of wood stretched between the frame and the end posts, or through a geometric curve.
Knee timbers in boat building. In woodworking, a knee is a natural or cut curved piece of wood. [1] Knees, sometimes called ship's knees, are a common form of bracing in boat building and occasionally in timber framing. A knee rafter in carpentry is a bent rafter used to gain head room in an attic.
A comparison of clinker and carvel construction. Carvel frames are much heavier than clinker ribs.. Carvel built or carvel planking is a method of boat building in which hull planks are laid edge to edge and fastened to a robust frame, thereby forming a smooth surface.
The particular name given depends on the context—the type of ship or boat, the arrangement, or even where it sails. In a typical wooden sailboat, the hull is constructed of wooden planking, supported by transverse frames (often referred to as ribs) and bulkheads, which are further tied together by longitudinal stringers or ceiling.
A currach (Irish: curach [ˈkʊɾˠəx]) is a type of Irish boat with a wooden frame, over which animal skins or hides were once stretched, though now canvas is more usual. It is sometimes anglicised as "curragh". The construction and design of the currach are unique to the west coasts of Ireland.
In traditional framing, transverse frames are attached at right angles to the keel, spaced between 2 and 3 feet (61 and 91 cm) apart. These are secured at the lower end to the keel or center keelson and at the upper ends to the deck beams. They are in two parts called floors and side frames and, while necessary, subtract from cargo space inside ...
