Boating Tidal streamTide tables

tide - The predictable, regular rising and lowering of water in some areas due to the pull of the sun and the moon. Tidal changes can happen approximately every 6 or 12 hours depending on the region.

 


TIDE IS EBBING, and there is little water left over the sill into the marina. In comes your average fibreglass bilge-keeler, doused sails aflogging at a speed that would put C class cats to shame.

Tide changes usually follow a regular diurnal (one tide change daily) or semidiurnal (two daily) schedule.

Tide: The vertical rise and fall of the mass of water in the oceans in response to the gravitational forces of sun and moon.

Tide rode Said of an anchored vessel that is lying to the tide rather than the wind.
Toggle A wooden pin with one end of a line seized to its middle to make fast to an eye.

Tide race or rip. Where currents run very fast causing broken water.
Rake
The inclination of the masts, funnel etc. forward or aft from the perpendicular.

tide table A set of data listing the timetable of low/high tides.
tiller A lever, attached to the rudder post, used for controlling the rudder (when steering).
toe rail Low bulwark on a small decked boat.

Tide: The flowing or swelling of the sea, or its alternate rising and falling, twice in each lunar day, due to the attraction of the moon and, in a less degree, of the sun; the alternate inflow and outflow produced by this on a coast, ...

Low Tide
The point of a tide when the water is the lowest. The opposite of high tide.
Lpg ...

A tide table. On your intended route, the tides in the Chesapeake and around Florida will be of little concern. Maine and the Carolinas, however, will be a different story.

Ebb tide: A receding tide.

EBB TIDE: A receding tide or current.
ENSIGN: The national flag, or ‘colours’ displayed from aft by all yachts.
EVEN KEEL: When a boat is floating on its designed waterline, it is said to be floating on an even keel.

Usually the average low tide water level. It is the level below which depths on a chart are measured, and above which keights of a tide are expressed.

ebb -- tide passing from high to low, with the current going out to sea
El Niño -- a warm inshore current annually flowing south along the coast of Ecuador.

Back and fill - To use the advantage of the tide being with you when the wind is not.
Backstays - Long lines or cables, reaching from the rear of the vessel to the mast heads, used to support the mast.

High Water - the tide's highest point before it starts to fall.
Hull - a boat's bottom shell.
Hull Speed - theoretical top speed for a displacement boat. (sailboat)
Knot - nautical mile (6,076 ft.) per hour ( a measure of speed).

Downstream current; Compare to tide and flood eddy A current of water, especially one moving in a circular pattern, ...

Slack water: The condition of the tide when there is no horizontal motion.
Slip: To let go by unshackling, as a cable.
Slop chest: Stock of merchandise, such as clothing, tobacco, etc., maintained aboard merchant ships for sale to the crew ...

High Water - the tide’s highest point before it starts to fall.
Hull - a boat’s shell.
Hull Speed - top speed for a displacement boat.
Knot - nautical mile per hour ( a measure of speed).

set -- the direction of the tide or current, the leeway course of the boat
shackle -- a metal link which can be open and closed for joining chain to anchor, etc.

Adrift- Floating free with the currents and tide, not under control. A rope may be adrift if comes out place.
Aft - At,near or towards the stern ...

fetch: the distance along open water or land over which the wind blows; to achieve a desired destination under sail, particularly with an adverse wind or tide.

Therefore it is still used in whaling boats and rowing boats which have to work against wind and tide, and in surf when the rudder will not act. It is not possible to assign any date for the displacement of the side rudder by the stern rudder.

Tide: The rise and fall of the sea water level due to the moon's gravity
Tidal drift: Strength of the tidal drift
Tidal stream: Current caused by the rise and fall of the tides ...

This allows them to operate in shallow waters, and if needed 'dry out' - become beached as the tide falls, the hull shape (or twin-keel layout) allows the yacht to sit upright when there is no water.

The night was pitchy dark, the tide running fiercely on the ebb at the rate of five miles an hour at the least. The water was very wild, as one can easily imagine.

Adrift- Floating free with the currents and tide, not under control.
Aft - At,near or towards the stern
After bow spring line- A mooring line fixed to the bow of the boat and leading aft where it is attached to the dock.

Look to see what the rest of the fleet are doing, remember about the tide.
Generally if in front of a bunch go high, if behind a bunch go low.
Check for gusts.
Watch for and use waves.
Body position, boat balance for wave riding.

If you are in a tidal zone, check the tide tables, things may be getting worse if the tide is letting out. In this case, one should try, if can be done safely, to place cushions between the hull and the bottom.

In typical Northwest summer's day fashion, the wind dies just before twilight and we are left in the middle of the channel battling a 3-knot flood tide.

Warning: Watch Out for the Tide! Most saltwater areas, including bays and even rivers near the coast, are affected by the tides. As the water level goes up and down, the boat rises and falls.

Notice whether a dock is a floating dock that rises and falls with the tide, (most all of them are) or if it is a fixed dock.

This takes a great amount of skill as you have to maneuver your boat according to rocky areas, the ebb and flow of the tide, and other navigational hazards.

TIDE - The periodic rise and fall of water level in the oceans.
TILLER - A bar or handle for turning a boat's rudder or an outboard motor.

EBB TIDE - A receding tide.
EVEN KEEL - When a boat is floating on its designed waterline, it is said to be floating on an even keel.
EYE OF THE WIND - The direction from which the wind is blowing.

A technique of tacking when the tide is with the ship but the wind is against it.
Overhaul -
To prevent the buntline ropes from chaffing the sails, crew were sent aloft to haul them over the sails. This was called overhauling.

Mean high water- The depth of the water at average high tide.
Mean low water- The depth of the water at average low tide.
Midships- The widest point on a boat.

Docking is pretty straightforward. Just approach the dock slowly, that's all. When tying up to the dock, leave the painter long enough to handle tide changes (you did not think about that one, uh?) if you are in an area that has a tide.

In many places, the direction of the current is determined by consensus or by the tide. It is important to be thoroughly familiar with the aids to navigation in your region.

When such an operation was to be carried out on a man-of-war it was necessary to have a proper wharf (the right beach might due), a proper turn of the tide, strong points on shore, and strong tackle and many men; ...
