Hull speed
The theoretical speed a boat can travel without planing, based on the shape of its hull. This speed is about 1.34 times the square root of the length of a boat at its waterline.

Hull Speed
Also displacement speed. The theoretical speed that a boat can travel without planing, based on the shape of its hull. This speed is about 1.34 times the square root of the length of a boat at its waterline.
HULL SPEED - The maximum practical speed of a displacement hull. To calculate, take the square root of the LWL (waterline hull length) and multiply by 1.34.
Hull Speed - Theoretical top speed for a displacement boat (sailboat)

The half of the glass nearer to the sextant frame is a mirror, the other half is clear. hull speed: the fastest a keelboat will go, usually dependent on length of the hull at the waterline.
A long counter increases the waterline length when the boat is heeled, so increasing hull speed.
But, if you are designing a very high-powered boat where the boat will operate at super hull speeds most of the time, you can gain sailing length by eliminating aft overhang and adding a chine.
Hull Speed - theoretical top speed for a displacement boat. (sailboat)
Knot - nautical mile (6,076 ft.) per hour ( a measure of speed).
Lee of the Land - near a shore which provides protection
from wind and waves.
Lee Shore - land downwind of a boat.
When this happens, the restrictions of hull speed are thrown out the window and even a heavy displacement cruiser may achieve a significant increase in speed. Control of the boat as you travel down the waves is of utmost importance.
Hull speed, the theoretical maximum speed of a displacement hull (nonplaning hull), is determined by multiplying the square root of her waterline length by 1.34. See hull. Speed made good, SMG; see made good.
entry - Hull qualifier in terms of hull behavior and efficiency in relation to wave action. A "sharper" entry implies a faster hull speed (for a racing hull).
A horsepower per meter of length can move a dinghy faster than oars. Two horsepower per meter can reach hull speed. Ten horsepower per meter will put a flat-bottomed dinghy on plane. Conventionally, the gas tank is placed under the rear thwart.
Displacement speed hull speed. The theoretical speed that a boat can travel without planing This speed is 1.34 times the length of a boat at its waterline.
Ditty bag: - a small bag for carrying or stowing all personal articles.
Plane: A boat planes when she sails over her own bow wave, so that only a small section of the hull is in the water. This in turn allows the boat to go faster than the theoretical maximum hull speed.
The overall length is irrelevant; overhangs fore and aft do not increase "hull speed" potential. WEATHER HELM A condition in which the tiller must be held toward the windward side of a sailing vessel in order to maintain course.
Helm: The boat's directional controls, tiller or wheel of a boat.
Hike: Leaning out over the side of the boat to counteract heel.
Hull: The body, or shell of a boat.
Hull Speed: The maximum speed a hull can achieve without planing.
Displacement hull boats have a maximum hull speed based on characteristics such as waterline length, draft, smoothness, etc. To overcome this limitation, planing hulls (speedboats) and hydrofoils rise out of the water at higher speeds.
