variation - Magnetic variation. The difference between magnetic north and true north, measured as an angle. Magnetic variation is different in different locations, so the nearest compass rose to each location on a chart must be used.
variation
Compass variable that accounts for the difference in degrees between true north and magnetic north.
ventilation
Air introduced into a spinning propeller from the water's surface.
Variation
The angular difference between the magnetic meridian and the geographic meridian at a particular location.
Veer
A shifting of the wind direction, clockwise in the Northern Hemisphere, counter-clockwise in the Southern Hemisphere.
variation - A compass "error" that occurs due to the fluid motion of the Earth's molten iron core. True north and magnet north are not always aligned.
vector - A line that represents both direction and magnitude (of force).
annual variation
The amount of by which variation changes up or down each year in a particular area. The annual increase or decrese is printed in the compass roses on each chart and may make a significant difference over a number of years ...
[edit] Variations
Basic Catamaran
Two main types of catamaran exist: the regular catamaran and the open catamaran, which features a trampoline between the hulls instead of plating.
variation
The difference in degrees between true north and magnetic north. Variation varies from area to area and year to year. It is shown on a chart's compass rose. See compass.

being of contrary names, take their difference.
Correction, 20° ...
Variation of siphon. A tube, pipe or hose through which a liquid can be moved from a higher to a lower level by atmospheric pressure forcing it up the shorter leg while the weight of the liquid in the longer leg causes continuous downward flow.
Variation - The difference between magnetic North and true North
Veer - A change of direction
Vertical Drive - Often used to describe the inboard outboard sterndrive ...
3. The variation in the crank effort tends to cause torsional oscillation of the same frequency, particularly in single or twocylinder engines.
A TOP SAIL SCHOONER a variation on the schooner, with square sails at the top of the foremast.
Combined effect of variation and deviation.
Course
The direction in which a boat is steered.
The compass course has added the magnetic deviation and the magnetic variation to the true course. Compass rose A circle on a chart indicating the direction of geographic north and sometimes also magnetic north.
Magnetic Bearing - The bearing of an object after magnetic variation has been considered, but without compensation for magnetic deviation.
SPRING TIDE: The tide with the most variation in water level, occurring during new moons and full moons. This is the time of the highest high tide and the lowest low tide. The opposite of a neap tide.
variation 1. The angular difference between true north and the direction of magnetic north at a given point on earth; 2.
The principal entries are: courses steered; distance run; compass variations, sea and weather conditions; ship's position, principal headlands passed; names of lookouts, and any unusual position, principal headlands passed; names of lookouts, ...
Magnetic variation: The variant angle of the difference between magnetic and geographic North Pole. The variation results from the movement of the magnetic North Pole.
There are many different versions and variations regarding size, form, material used, thickness, etc. for each type. And then sails are categorized in light wind sails and gale sails as well.
World Magnetic Model (WMM) - The WMM provides an estimated magnetic variation for any position on Earth. The WMM is a product of the United States National Geospatial-Intelligence Agency (NGA). The U.S.
Timid Virgins Make Dull Company at Weddings (Or "Add Whiskey.") This is the formula for converting true directions or courses to compass readings: True plus Variation equals Magnetic heading.
Both the International and the Inland version carry the same message, despite slight variations in wording. A vessel restricted in ability to maneuver (1) must be unable to keep out of the way of other vessels (2) because of the nature of its work.
A device which measures current and water pressure variations. If deployed in shallow water current and pressure data can be converted to wave height, period and direction.
The tide with the least variation in water level, occurring when the moon is one quarter and three quarters full. The lowest high tide and the highest low tide occur at neap tide. The opposite is the spring tide.
Noon Sight ...
There are so many variations available to this interior I have to think that one would strike your fancy. The aft bulkhead of the pilothouse is all glass, powerboat style.
Once the line leaves the marine toilet ("head") there is considerable variations between boats. Some boats do not have a direct overboard discharge system. Some boats have a "Y" valve which allows for waste discharge before it enters the holding tank.
A change or variation. b. The quality of being changeable; mutability. 2. Often vicissitudes. One of the sudden or unexpected changes or shifts often encountered in one's life, activities, or surroundings.
The following hull types are variations of planing and displacement hulls.
...
WARP Any variation from a true and plane surface. It includes bow, cup and twist and is often caused by irregular seasoning. WATERLINE LENGTH-Significance: One of the factors used to determine the speed potential of a displacement boat.
Thermal Container
A container built with insulating walls, doors, floor and roof by which heat exchange with the environment is minimized thus limiting temperature variations of the cargo.
The previous method presupposes you can get to the outside of the hull. However, a doubler can be applied from the inside using the same method with the following variations.
salts will tell you there are no "ropes" on a boat at all, just lines and sheets. These lines must be tied to things, around things, to other lines, on cleats, etc. Over the centuries sailors have devised literally hundreds of knots and variations ...
What is the bottom like?
Is it suitable for properly securing the type of anchor aboard the vessel?
Is the tide rising or falling? The length of the line must be determined by estimating water level variations.
Most are single-masted "Bermuda sloops" (not to be confused with the type of traditional Bermudian ship known as a Bermuda sloop), with a single foresail of the jib or genoa type and a single mainsail (one variation of the aforementioned Bermuda ...
A magnetic course is the direction of the ship's heading relative to magnetic north; a compass course is the direction of the ship's heading based on the ship's compass (including errors of deviation and variation).
