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 ...
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 ...
There are five basic types of construction used in building a wooden ship model hull: . Solid wood hull sawn and carved from a single block of wood. Gluing together two thinner blocks of wood so that a block is formed with the seam vertical, so that the seam will show running down that surface of the block which is to be the deck.
These hulls generally have one or more chines and the method is called Ply on Frame construction. [7] 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.

The word "keel" comes from Old English cēol, Old Norse kjóll, = "ship" or "keel".It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work De Excidio et Conquestu Britanniae, under the spelling cyulae (he was referring to the three ships that the Saxons first arrived in).
Keel laying is one of the four specially celebrated events in a ship's life; the others are launching, commissioning, and decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber ...
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. Girders are commonly used to ...
In shipbuilding, the scantling refers to the collective dimensions of the framing [1] (apart from the keel) to which planks or plates are attached to form the hull. [2] The word is most often used in the plural to describe how much structural strength in the form of girders, I-beams, etc., is in a given section.
