SCOPE: Technically, the ratio of length of anchor rode in use to the vertical distance from the bow of the vessel to the bottom of the water. Usually four times the depth with chain and six to seven times the depth with warp.
scope - The amount of anchor cable to use; the ratio of anchor line in use to the vertical distance from the bow to the water's bottom. Usually six to seven to one for calm weather and more scope in storm conditions.
scope
The ratio of anchor rode to vertical depth.
scud
To run before the wind in bad weather.
Scope
The ratio between the length of the anchor rode and the depth of the anchor. A scope of 7:1 is usually used, depending on the holding ground. Too little scope can cause the anchor to drag.
Screw
A propeller.
ScopeThe ratio of the length of an anchor line, from a vessel's bow to the anchor, to the depth of the water.
ScrewA boat's propeller.
Sea AnchorAny device used to reduce a boat's drift before the wind.
- Scope is defined as the ratio of the depth (draft plus freeboard) divided into the length of anchor line paid out. The typical minimum scope is from 3-5 with 7 being the best practical.
Periscope
Tube used for looking from a submerged vessel to the surface.
Petty Officers ...
Scope
The length of the anchor rode relative to the depth of the anchor. For example 100 feet of anchor rode in 20 feet of water would be a scope of 5:1. A scope of 7:1 or more is usually used depending on the holding ground.
scope
1) The angle of the anchor rode to the water's bottom as indicated by the ratio between, on one hand, a) the length of rode paid out and, on the other hand, b) the water's depth plus the freeboard.
scope -- the length or extent of anchor rode
scopolamine -- a drug prescribed for motion sickness
Scull - moving the rudder back and forth in an attempt to move the boat forward ...
Scope
The ratio of the length of the payed out anchor line (Rode) to the height of the chock above the bottom of the body of water.
Scupper ...
Scope - Length of anchor rode compared to depth of water at high tide and height to the bow 5 to 1 is considered a minimum with 10 to 1 in bad weather. All chain rodes need a scope of 3 to 1 up to 5 to 1 ...
Once the correct scope is laid, it can help holding power, by putting the yacht gently in reverse and tensioning the tackle until the anchor is well buried and the yacht makes no more way.
Once the desired scope is laid out (a minimum of 8:1 for setting the anchor, and 5:1 for holding, though the preferred ratio is 10:1 for both setting, and holding power), the vessel should be gently forced astern, ...
PERISCOPE An instrument used for observing objects from a point below the object lens.
This is the reason that you put out the first fifty feet of scope. It gives you line to play with plus it guarantees you that you had enough line to properly set your anchor. Once you get your boat back head to wind start the backing process again.
(See Trans. Inst. Na y. Archs. 1892.) An interesting application of the gyroscope to the diminution of rolling was devised by Dr O. Schlick, and fitted by him to the S.S. " See-bar.
also the seaman's name for a telescope.
Global Positioning System (GPS) - A navigation system using satellite signals to fix a position with great accuracy.
There are some very nice hiking sticks made that extend the scope of the tiller and allow you to sit outboard to windward or leeward. Once anchored your tiller can hinge up and be entirely out of the way.
The anchor is taken out a distance with a dinghy to a proper scope of (7:1). Tighten the rode as the boat is moved back and forth by the waves or use a winch or, if present, the anchor's windlass to pull the boat off the shoal.
Recommended lengths: if you only have chain, your scope ratio is at least 5 to 1 (ex.: if depth is 20 ft + aft from roller to the water, let 125 ft. of chain out. More in strong winds.) If you have chain and rope, your ratio is 7 to 1.
There are other differences between the International and Inland versions of Rule 38 besides the date from which the clock begins to run. The Inland exemptions are broader in scope, for example, ...
Therefore I say let your motto be caveat emptor when you go cruising about in search of either a cheap marine telescope or binocular among marine store dealers or pawnshops.
The fluid in the glass (in most cases water) would move up and down the stem as the pressure of the surrounding atmosphere changed. These movements were used to predict changes in the weather. also the seaman's name for a telescope.
Scope - ratio of anchor rode length to vertical distance from the
anchor lead (chock or roller) to the bottom.
Scupper - water drain hole in the deck of a boat.
Sidelights - a boat's red and green lights.
SCOPE - The ratio of length of an anchor line to the depth of water. The "depth" includes the height of the chock above the water, sometimes thought of as the length of rode.
SCUPPER - An opening in a deck or cockpit permitting water to drain out.
