SAND BAR: An area in shallow water where wave or current action has created a small, long hill of sand. Since they are created by water movement, they can move and may not be shown on a chart.
current

Current ( Go To Top )
Staying on course is not as simple as pointing your boat towards your destination, you must compensate for current.
CURRENT: The horizontal movement of water.
CUTTER: Similar to a sloop except sails are arranged so that many combinations of areas may be obtained.
current - The movement of water, due to tides, river movement and circular currents caused by the motion of the earth.

If a current or wind may start the boat moving before it is well tied up, always secure first the end facing the wind or current. If the bow is facing the wind or current, for example, tie up the bow line first before the boat starts moving backward.
Wind, currents and swell all effect the boat's movement, but let's ignore them for a moment and look at the simple mechanics of steering. The hull cuts through the water as it moves.
tidal current
Horizontal water movement caused by the tides rather than by the wind (wind-driven current).
If the current is flowing away from your home port, it will be easy for you to get out for the day.
*If the current is enough for your boat to swing, consider using two anchors in both directions the current is moving. When you approach the dock, have your fenders in the deployed position.
Winds and currents can change a vessel's course. Always allow leeway for current and wind.
A incoming current.

The use of echo sounders, radio, and various electronic satellite and land based position finders to determine a boat's location.
EBB A receding current.
FATHOM Six feet. FENDER A cushion, placed between boats, or between a boat and a pier, to prevent damage.
Counter Current - That part of the water which is diverted from the main stream of a current and as a result flows in the opposite direction.

countercurrent: a current flowing in a direction opposite to that of the principal current.
Supply Current - the typical current that must be supplied to a product along with the supply voltage.
Supply Voltage - the amount of voltage the user must supply to a product for the product to work properly.
Electromagnetic Current Meter
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.

A lookout on a vessel at anchor is required, with the level of effort depending upon the location of the anchorage, depth of water, type of ground tackle, wind, currents, waves, and so forth.

FENDER - A cushion, placed between boats, or between a boat and a pier, to prevent damage.
Stemming such a current it would not do to shorten sail if one wished to pass Cape Tourmente and get into quiet water, the Isle of Orleans and the north shore, so we let every sail stand, cleated the sheets tightly and let her drive.
A good site will probably be in a protected bay where there is calm water and not much current. A municipal bay may not be a good place due to pollution that contaminates the water and discourages sea life.
While the general aesthetic approach to this design is a vintage look with long overhangs and minimal freeboard, the hull shape is strictly modern and owes much of its shape to the current America's Cup class.
As long as the wind or current is strong enough to keep both vessels lying in the same direction, this is fine.
THIRD LESSON - WIND AND WAVES, TIDES AND CURRENT, NAVIGATION
How the wind over open water, shallow water and into currents affects waves and sailing conditions; tide and current; learning the chart symbols, ...
Leeway -The sideways movement of the boat caused by either wind or current.
LeechAfter edge of a fore and aft sail
lifeline -- stout line around the deck of the boat to keep crew from falling overboard ...
the particular oscillation that is recurrent in the period of the swell. The amplitude of roll at any instant is therefore the sum of the amplitudes due to the forced oscillation and to an arbitrary free oscillation in still water.
The distance read from a log can be affected by currents, leeway and other factors, so those distances are sometimes corrected to a distance made good.
A book containing all current data: navigational, tidal, astronomical and so on. It is published annually.
nautical mile
One minute of latitude; approximately 6076 feet - about 1/8 longer than the statute mile of 5280 feet.
Is the anchorage sheltered from the weather (wind, strong currents, etc.) and will it remain that way?
What is the weather forecast?
What is the bottom like?
Is it suitable for properly securing the type of anchor aboard the vessel?
Electricity's main drawback is the large amount of current most appliances need to operate properly. Large current demands that many appliances need require boats to be hooked up to shore power or to have a generator.
