A gaff rig is named for the extra spar, called a gaff, which is raised with the sail and results in a four-sided mainsail (and/or mizzen). Gaff rigged boats are generally less efficient at sailing upwind. The end of the gaff near the mast is called the throat and the end furthest ...
sailors eventually developed airfoil sails that allow sailing in directions other than downwind. Apolar diagramfor a vessel gives you a useful chart of how fast it can go at a given angle to the wind. Sailing directly into the wind is also known as being “in irons” as it doesn’t get...
Marigold was now upwind, which would mean motoring, and motoring upwind in waves and a good breeze is exactly what Great Auk will not do. Heartbreaking as it was, Great Auk and I sailed away, and little Marigold disappeared in the night. Of course the worst, scariest part of the story...
It is somewhat less known, but nevertheless true, that one can (in principle) do both at the same time – sail against the wind (even directly against the wind!) at speeds faster than the wind. This does not contradict any laws of physics, such as conservation of momentum or energy (...
Finally, on both sails in the picture you will see the'telltales'. These give you an idea as to how well the sail is set. When sailing on an upwind leg - the telltales on both the windward and leeward side of the jib should point aft. ...
The CARAC is a special Class 40, as I´ve learned from Marc Lombard because she is made to go fast upwind also. When Marc described the features of this yacht from his naval architectural standpoint it all was of course very theoretical – seeing the boat now here mooring right in fron...
is not the case on boardRaven. Due to its weight and inertia, it has moderate acceleration and only ever sails in displacement or semidisplacement modes. Water ballast provides righting moment upwind and, when down-speed, the foils provide minimal lift, and they also can be used to ...
A cleat is a piece of hardware designed to hold a line. In the most traditional sense, a cleat is a piece of metal or wood that is shaped somewhat like an anvil. A special knot known also as a cleat is used to tie a line to these traditional cleats. ...
There will be no downwind sails as the angles are high and fast, upwind virtually similar to downwind with the apparent wind so far forward. The concept of the double-skinned mainsail is to be able to manipulate each skin independently in order to power the sails for takeoff and depower ...
