First, a diagram of the sails on a boat in wind direction or a project.

Imagine the wind moves through the sails like a rope that goes through a fight.

If you extended the boat can be frozen in ice, and not back, continues to turn, stop moving the air with the sails, but the boat. It would be a fixed role.

The upper part of the chart is like a ship in the ice:

In the lower block in this system is like a sailboat in the water. When the Wind, "" pulled by the sail, the boat moves indicated above the water, usually in the right direction.

Of course, the sails of a ship does not look into the wind 180 degrees, the role of the diagram.

It is the turn of the wind, which generates more force on the sail and the power to transfer the body of the mast, boom and rigging.

In essence, a role is a device for the change in the direction of a force. A sailboat can move in a different direction of wind direction. While you can not faster than the wind, the wind, multiplied by the aerodynamics of the sail. And it is mobile, where the water depth is greater than in the project.

It always makes me laugh when people say that the yachts can sail faster than the wind did, regularly, I do, I twice this weekend. There is a large gap between theory and practice, it seems.

It is well established.

Move In my 'C-Boat "no blocks (pulleys) on the spring. The idea is to influence move back and forth as they navigate.

There are also blocks of furniture travelers. Once again, the form of a sail.

Is that what you had in mind?
