BILGE BRACKET

A vertical transverse flat plate welded to the tank top or margin plate and to the frame in the area of the bilge.

FLOOD CURRENT

The movement of a tidal current toward the shore or up a tidal river or estuary. In the mixed type of reversing current, the terms greater flood and lesser flood are applied respectively to the flood currents of greater and lesser speed of each day. The terms maximum flood and minimum flood are applied to the maximum and minimum speeds of a flood current, the speed of which alternately increases and decreases without coming to a slack or reversing. The expression maximum flood is also applicable to any flood current at the time of greatest velocity. The opposite is EBB CURRENT.

VANE

A fixed or adjustable plate inserted in a gas or air stream used to change the direction of flow.

FREEBOARD DEPTH

(D): The moulded depth measured amidships, from the top of the keel to the top of the freeboard deck beams at side, plus the thickness of the stringer plate if no wooden deck is fitted. If a wooden deck is fitte

ORIFICE DISCHARGE COEFFICIENT (Cd)

The ratio of the actual flow through an orifice to that of the theoretical or isentropic flow through an orifice. Basically this parameter is a measure of the orifice efficiency. Valves are dimensionless and range from 0.61 for a thin-plate orifice to 0.85 for thick plate square-edged orifices, and up top 0.90

BELLOWS GAGE

A device for measuring pressure in which the pressure on a bellows, with the end plate attached to a spring, causes a measurable movement of the plate.

TRUE MOTION DISPLAY

A type of radarscope display in which own ship and other moving targets move on the plan position indicator in accordance with their true courses and speeds. All fixed targets appear as stationary echoes. However, uncompensated set and drift of own ship may result in some movement of the echoes of stationary targets. This display is similar to a navigational (geographical) plot.

EBB CURRENT

The movement of a tidal current away from shore or down a tidal river or estuary. In the mixed type of reversing tidal current, the terms greater ebb and lesser ebb are applied respectively to the ebb tidal currents of greater and lesser speed of each day. The terms maximum ebb and minimum ebb are applied to the maximum and minimum speeds of a current running continuously. The expression maximum ebb is also applicable to any ebb current at the time of greatest speed

OXTER PLATE

The plate in the curve between the shell plating and the top of the stern post.

LIMIT OF LIABILITY

The financial limit a vessel owner must pay when they or their vessel is found to be liable for an incident, such as an oil spill, or collision. This used to be a fixed formula, such as 3 times the value of the vessel and its cargo, but with OPA 90 this limit has no real stopping point depending on individual States requirements on top of the federal limit of liability.
