English term

deadrise

GBK English to Spanish Tech/Engineering Ships, Sailing, Maritime
Definition from marinewaypoints.com:
The measurement of the angle between the bottom of a boat and its widest beam. A vessel with a 0º deadrise has a flat bottom, high numbers indicate deep V shaped hulls.
Example sentences:
There are, however, many good reasons for choosing a V bottom hull over a flat one. Someone experienced in observing these wave patterns might infer the angle of deadrise just from looking at the waves generated by the boat. (bluejacketboats.com)
A higher deadrise angle will give better performance in rough waters, but a lower deadrise angle is more hydrodynamically efficient and thus can generate better acceleration and a faster top speed. (Jelsoft Enterprises Ltd.)
This transducer’s unique design allows it to be mounted close to the vessel’s centerline without drilling holes, and is able to correct for the hull’s deadrise angle. (Airmar Technology Corporation)

Peter Guest Nov 16, 2009:
good The simple explanation is quite correct as far as it goes. (Also not all boats are hard-chined.) Unfortunately it does not provide a translation for the term deadrise. There's no difficulty about what it is or how it used. There doesn't seem to be a Spanish term used in exactly the same way. The term deadrise used alone means the height from keel to limit of the bilge curve. the deadrise angle is neatly described in your reference. Deadrise angle is ángulo de pantoque, but pantoque is generally bilge or bottom according to some people…
Emma Ratcliffe Nov 16, 2009:
Well I found this simple explanation:
The amount of V shape in the bottom of a hull is known as deadrise. Technically, deadrise is an angle measured upward from a horizontal plane at keel level. If you stand in front of or behind a hard-chined boat and look along the hull, you will be able to judge the amount of deadrise.A flat-bottomed boat has a dead-rise angle of 0 degrees; a deep-V hull has about 24 degrees of deadrise. The amount of deadrise varies with the intended use of the boat. A flat-bottomed boat rises onto a plane quickly and provides a comfortable, stable ride in calm water—but it will pound heavily in rough water. A deep-V hull provides a softer ride in those conditions, but will be more reluctant to rise onto a plane. An all-purpose hull—a common compromise—has a dead-rise angle of about 15 degrees.

ángulo de pantoque

Deadrise is the meaning is la distancia vertical entre la quilla y la curva o vuelta del pantoque. The deadrise angle which is the angle formed between the keel and the end of the curve of the bilge. Difficult to find exact mentions…
Example sentences:
k= 1,0 respecto de un buque de pantoque redondo que no tenga quillas de balance ni quilla de barra; k =0,7 respecto de un buque de pantoque quebrado; (Normativa Marítima)

agree Emma Ratcliffe : I think yours is the best explanation, because there is no exact wording in spanish to describe it.

Puntal

Creo que es la traducción exacta de lo que buscas
Definition from DRAE:
Altura de la nave desde su plan hasta la cubierta principal o superior.
Example sentences:
Puntal del buque: Es la medida vertical desde el canto superior de la quilla hasta la unión de la traca de cinta con la cubierta principal. (Wikipedia)
Peer comment(s):

disagree Peter Guest : deadrise is only to the height to the end of the curve of the bilge. Puntal is depth

Astilla muerta

También se encuentra en el diccionario de la Organización Marítima Internacional (IMO por sus siglas en inglés), como astilla muerta y también existe el término "ángulo de astilla muerta". Pueden ver ilustración en las imágenes de google si buscan en inglés "deadrise" y verán que concuerda con la definición de Por Tierra Mar y Aire.
Definition from Por Tierra Mar y Aire:
ASTILLA MUERTA.- es la altura en el costado del buque que hay desde un plano paralelo a la flotación que pasa por la quilla (plano base o línea base, en proyección) y el plano tangente al fondo.
Example sentences:
Guadalupeko Nº de Construcción 131. Se trata de una embarcación para pesca local con artes menores con propulsión a motor y formas de semidesplazamiento, con una buena astilla muerta, proa lanzada y popa de estampa. (Astillero Herso)
Sedan Bridge La majestuosa potencia de este magnífico 58 Sedan Bridge sobrepasa a cualquier otro yate de su clase. Los impresionantes motores gemelos diesel MAN V8 y una excepcional capacidad de combustible hacen que este musculoso yate sea capaz de llevarle allí donde su corazón lo desea. Para garantizarle una navegación fluida y estable, hemos construido este bello yate con una manga excepcionalmente ancha y una astilla muerta más abrupta, hemos añadido un propulsor de proa y hemos incluido aire acondicionado estándar en el puente. (International Searay)
Cascos monohédricos Los cascos monohédricos típicos ('monohedron hulls' en inglés), presentan el codillo paralelo a la línea de quilla (o al alefriz, si hubiese quillote), mas o menos a partir de la mitad de la embarcación hacia popa, creando así un ángulo de astilla muerta (o “V”) constante en esta zona del casco. (Gestenaval, Ing. y Consultoría Naval)
