Windage
Windage
Either the wind drag itself, or the extent of the drag-creating parts of a craft which are exposed to the wind, as in, ‘She's got a lot of windage', meaning that she has a high superstructure (See also: Top hamper) ...


WINDAGE: The sum of those parts of a boat other than sails that catch the wind.
WINDEX: Trade name that has passed into general usage. A mast head fitting with a wind vane arrow and two aft-facing legs that approximately coincide with the close-hauled apparent wind angle.

windage - Any form of wind resistance.
windfall - An unexpected advantage or acquisition of treasure.
wind jamming - A old-fashioned slang term for sailing by the wind. Wind jammers, sailing ships.

Windage
The amount of a boat, sail or other object that the wind can push on.
Windlass
A mechanical device used to pull in cable or chain, such as an anchor rode.

WINDAGE The surface area of the boat that will catch the wind.
WINDLASS A mechanical winding device used to pull up the anchor chain.
WINDWARD Towards the direction of the wind.

~: Wind resistance of the boat.
Windbound: A condition wherein the ship is detained in one particular station by contrary winds.
Wind-over-tide: Sea conditions with a tidal current and a wind in opposite directions, leading to short, heavy seas.

~. Surface exposed to the wind providing resistance; as in: The crow's nest on that boat creates weight aloft and ~.
windlass. Winch for the anchor rode; as in: Many modern boats have an electric windlass with a remote control.
windward.

This reduces the windage on the blade thus reducing the effort expended.
Feathering Prop - A propeller that can have the pitch of its blade changed to reduce drag when not in use.
Fend Off - To prevent contact with an object while bringing the ship alongside.

Le Blond observes, in his Elements of war, that the wad is necessary to retain the charge closely in the chamber of the cannon, so that it may not, when fired, be dilated around the sides of the ball, by its windage as it passes through the chace; ...

Every boat has different characteristics as far as windage is concerned. The more the windage the larger ground tackle that is needed. Take down all sails, canvas, auxiliary outboard and any thing else that might cause windage problems. Don't forget to lock your boat when you leave.

Another common problem while on the hook is 'anchor sailing' or sheering, which is caused by windage from a boat's hull, superstructure and rigging. With each wind shift the bow falls off, only to be brought up short by the anchor rode, which in turn forces it to point in the opposite direction.

under bare poles - Having no sails up. In heavy weather the windage of the mast and other spars can still be enough to move the boat.
under the lee - On the lee side of an object, protected from the wind.
under way - A vessel in motion is under way.

Having no sails up. In heavy weather the windage of the mast and other spars can still be enough to move the boat.
under the lee
On the lee side of an object, protected from the wind.

The halyard may also rise up through the mast to reduce windage aloft, as in the boat shown in this photo, and exit at a point near the deck. Pulling down on the halyard raises the sail. In most cases the mainsail is raised and the boat is underway before the jib is raised or unfurled.

Yachts should carry at least two anchors, the bower and kedge. It is difficult to lay down hard and fast rules on anchor size, as windage varies from boat to boat. Expert advice for your type of craft should always be taken.

Feathering Oars:
The turning of the blade of an oar from the vertical to the horizontal while it is being taken aback for the next stroke. This reduces the windage on the blade thus reducing the effort expended.

This is one of the lowest drag (the sailing term is windage) sails, and it is not easy to manage.
A Bermuda or Marconi sail is a triangular sail with one point going straight up.

Generally less efficient for top performance, but does have less windage aloft when sail is reduced. JIBHEAD RIG - In a jibhead rig the forestay does not attach to the masthead but at a point lower on the mast where the top of the jib meets the mast. KETCH RIG Two masts, three sails.
