Stern - Elliptical Stern

Elliptical Stern

The visual unpopularity of Seppings' circular stern was soon rectified by Sir William Symonds. In this revised stern, a set of straight post timbers (also called "whiskers", "horn timbers", or "fan tail timbers") stretches from the keel diagonally aft and upward. It rests on the top of the sternpost and runs on either side of the rudder post (thus creating the "helm port" through which the rudder passes) to a point well above the vessel's waterline. Whereas the timbers of the transom stern all heeled on the wing transom, the timbers of the elliptical stern all heel on the whiskers, to which they are affixed at a 45̊ angle (i.e., "canted") when viewed from overhead and decrease in length as they are installed aft until the curvature is complete. The finished stern has a continuous curved edge around the outside and is raked aft. Other names for the elliptical stern include a "counter stern," in reference to its very long counter, and a "cutaway stern." The elliptical stern began use during the age of sail, but remained very popular for both merchant and warships well into the nautical age of steam and through the first eight decades of steamship construction (roughly 1840–1920), despite the fact that the design left the rudder exposed and vulnerable in combat situations.

Famous quotes containing the word stern:

    The rich earth, of its own self made rich,
    Fertile of its own leaves and days and wars,
    Of its brown wheat rapturous in the wind,
    The nature of its women in the air,
    The stern voices of its necessitous men,
    This chorus as of those that wanted to live.
    Wallace Stevens (1879–1955)
