Chine (boating)
A chine in boat design is a sharp change in angle in the cross section of a hull. The chine typically arises from the use of sheet materials (such as sheet metal or marine ply) as the mode of construction.
Using sheet materials in boat construction is cheap and simple, but whereas these sheet materials are flexible longitudinally, they tend to be rigid vertically. Examples of steel vessels with hard chines include narrowboats and widebeams; examples of plywood vessels with hard chines include sailing dinghies such as the single-chined Graduate and the double-chined Enterprise. Although a hull made from sheet materials might be unattractively "slab-sided", most chined hulls are designed to be pleasing to the eye and hydrodynamically efficient.
Hulls without chines (such as clinker-built or carvel-built vessels) usually have a gradually curving cross section.
A hard chine is an angle with little rounding, where a soft chine would be more rounded, but still involve the meeting of distinct planes. Chine log construction is a method of building hard-chine boat hulls. Hard chines are common in plywood hulls, while soft chines are often found on fiberglass hulls.
Traditional planked hulls in most cultures are built by placing wooden planks oriented parallel to the waterflow and attached to bent wooden frames. This also produced a rounded hull, generally with a sharp bottom edge to form the keel. Planked boats were built in this manner for most of history.[citation needed]
The first hulls to start incorporating hard chines were probably shallow-draft cargo-carrying vessels used on rivers and in canals.
Once sufficiently powerful marine motors had been developed to allow powerboats to plane, it was found that the flat underside of a chined boat provided maximum hydrodynamic lift and speed.
The scow in particular, in the form of the scow schooner, was the first significant example of a hard-chine sailing vessel. While sailing scows had a poor safety reputation, that was due more to their typical cheap construction and tendency to founder in storms. As long as it sailed in the protected inland and coastal waters it was designed to operate in, however, the sailing scow was an efficient and cost-effective solution to transporting goods from inland sources to the coast.[citation needed] A good example of this is the gundalow.
