The rise of the bottom of a boat from the keel outward to the turn of the bilge. A flat-bottomed boat has no deadrise. The sharper the angle of the V in a V-bottomed boat the greater her deadrise. In planing boats a flat bottom gives best speed for a fixed power, but the ride is harsh.
deadrise - 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.
Degrees of V-shape hull angle measured at the transom of planing powerboats.
Blunt-bowed power boat generally characterized by an open deck and generous passenger seating.
Deadrise - The design angle between the keel and horizontal.
Deadwood - A wooden part of the centerline structure of a boat, usually between the sternpost and amidships.
Decks - A permanent covering over a compartment, hull or any part of a ship serving as a floor.
deadrise - Expressed as an angle, it is height between the vessel's bottom and its widest beam.
dead water - The water in a vessel's wake, close to her sternpost, that follows the ship.
dead weight - Concentrated weight in a vessel's pattern, such as a heavy cargo of ore or ballast.
~ - the angle above horizontal of the bottom from the centerline (keel) to the chine, measured in degrees. A flat bottomed boat would have zero deadrise. ~ is typically measured at the transom. If measured at some other point, that point should be specified.
The design angle between the keel and horizontal. A vessel with a 0 degree deadrise has a flat bottom where as a a higher degree will indicate a deeper 'v' shaped hull.
~ - The angle from the bottom of the hull (not the keel) to the chine.
DECK - A permanent covering over a compartment, hull or any part thereof.
DEEP-V HULL - A hull designed to go through the water and not capable of planning speed.
The angle at which the bottom rises from where it joins the keep to the turn of the bilge, or chine.
~ - The design angle between the keel and horizontal.
Deadweight - A common measure of ship carrying capacity. The number of tons (2240 lbs.) of cargo, stores and bunkers that a vessel can transport.
~: The design angle between the keel (q.v.) and horizontal.
Dead run: See running.
Deadwood: A wooden part of the centerline structure of a boat, usually between the sternpost and amidships.
~ - The design angle between the keel (q.v.) and horizontal.
Decks - the structures forming the approximately horizontal surfaces in the ship's general structure. Unlike flats, they are a structural part of the ship.
RISE OF BOTTOM See deadrise. RISER The upright board of a stair. A pipe extending vertically and having side branches. RISINGS The fore and aft stringers inside a small boat, secured to the frames, and on which the thwarts rest.
~: Rise of the bottom from baseline to molded breadth measureed amidships. Also called "rise of floor" or "rise of bottom". Full-bodied ships, such as cargo ships and tankers, have little or no deadrise, while fine-lined ships have much greater deadrise along with a large bilge radius.
flat-bottom boatType of boat or hull shape with very little or no deadrise.
Deep-Vee - A hard chine power boat having a 15 degree or more angle deadrise at the transom.
Dinghy A small boat, usually carried on hauled behind a bigger boat
Displacement-The weight of the water displaced by the vessel.
The rise or upward slant of the bottom of the ship from the keel to the bilge, the measurement of the angle between the bottom of a boat and its widest beam. A vessel with a 0Âº deadrise has a flat bottom, high numbers indicate deep V shaped hulls.
DEEP VEE A hard chine power boat having a 15 degree or more angle deadrise at the transom. DISPLACEMENT HULL A hull that will not exceed a fixed speed which increases with the length of the hull.
