The spinnaker pole is rigged to run from the base of the mast, [1] where there is a special fitting for attaching one end of the pole, out to windward over the side of the boat. There, one of the control lines of whichever sail it is to be used with is run through a fitting on the other end of the spinnaker pole. This allows for more precise ...
Polar diagram comparing the speeds and carrying angles of symmetrical with asymmetrical spinnakers when sailing Two sailboats flying asymmetrical spinnakers beam reaching in light wind On cruising sailboats, a modestly sized asymmetrical spinnaker can be tacked to a centerline bow pulpit, anchor roller or a furled headsail, and can be known by ...
Watercraft navigation lights must permit other vessels to determine the type and relative angle of a vessel, and thus decide if there is a danger of collision. In general, sailing vessels are required to carry a green light that shines from dead ahead to 2 points (22 + 1 ⁄ 2 °) abaft [note 1] the beam on the starboard side (the right side from the perspective of someone on board facing ...
In contrast to a simple light switch, which is a single pole, single throw (SPST) switch, multiway switching uses switches with one or more additional contacts and two or more wires are run between the switches. When the load is controlled from only two points, single pole, double throw (SPDT) switches are used.
When the boat jibes, the spinnaker pole will be moved from one side of the boat to the other, causing the sheet to become the guy and vice versa. A foreguy may also be used to control the height of the spinnaker pole. It is attached either to the end of the pole or to a bridle on the bottom of the pole, and runs through a padeye on the foredeck ...
[2] Spinnaker – Some sailboats use a symmetrical spinnaker—a three-sided, parachute-like sail—off the wind. The windward lower corner of a spinnaker is attached to a horizontal pole, coming from the mast to the lower corner of the sail—controlled by a line, called a guy—and the other lower corner is attached to a line that acts as a ...

A polar diagram, or polar plot, is a graph that shows a sailboat's potential speed over a range of wind speeds and relative wind angles. [1] It normally consists of the right side of a line chart with the radius representing the yacht speed and the angle representing the wind direction blowing from top to bottom.
