-TWS (True Wind Speed) The speed of the wind, (if the boat was a stationary object). Dec 31, 2021 · This possibility is enhanced when sailing in strong currents, which is common in the Pacific Northwest, and in other places like the Bermuda Races that have to deal with Gulf Stream eddies and meanders, with currents up to 4 kts. perhaps at anchor or alongside) then the wind speed and direction are the TRUE wind speed and direction. The wind direction and our destination determine our point of sail, and consequently, we trim the sails accordingly. The other boat is clear ahead. In addition, there is the term TWA (True Wind Angle) which is the angle between the boat’s heading and the true wind direction (TWD). What does TWA stand for in Sailing? Get the most popular TWA abbreviation related to Sailing. In light winds you may come up as high as 90 TWA, and apart from that this sail will cover all angles from 120 to 160 TWA in medium conditions. When the boat is hauled at the end of the season, there is always some debris on or in the impeller that I believe compromises the speed information. Proposal Amend the definition Clear Astern and Clear Ahead; Overlap as follows: Clear Astern and Clear Ahead; Overlap One boat is clear astern of another when her hull and equipment in normal position are behind a line abeam from the aftermost point of the other boat’s hull and equipment in normal position. True wind speed and direction will vary dependent on how close to the surface the observer is located. The asymmetric spinnaker, also referred to as a gennaker is an all-round asymmetric downwind sail with optimized shape and size to make the sail stable for easy sailing. Generally, these formulas and plotting routines solve for true wind angle (TWA) based on AWA, AWS and S. . The principle is to look at TWA directly to check if the boat is hitting it’s TA. This article discusses the leeway phenomena, lift, and the net errors introduced in wind readings and how to compensate them. g. It operated from 1930 until 2001, when it was absorbed by American Airlines. Can be used with a spi-sok for easier handling. It underwent three bankruptcies and was eventually acquired by American Airlines. With TA upwind and downwind set (Menu>Performance>) at 45° and 135° respectively, below are figures illustrating what TWA to look out for. In a few words a Polar contains a collection of boat speeds at selected relative true wind angles (TWA) and speeds (TWS) telling you how fast your boat will sail at these conditions. Feb 27, 2025 · True Wind Angle (TWA) is a crucial concept in maritime navigation and sailing. It's a measure that goes beyond the simple direction of the wind and incorporates the boat's motion, providing a more accurate picture of the wind's influence. Today, TWA is remembered for being an early pioneer of air travel in the United States. Aug 30, 2023 · While TWA eventually declared bankruptcy and was purchased by United Airlines in 2001, the TWA brand continued operating until 2003. Unless there are environmental or tactical reasons to do otherwise, that is the way you best progress upwind—and any target that is not on the layline is by definition upwind. -TWA (True Wind Angle) The angle of the wind, relative to the boat if it was stationary. Jan 16, 2026 · Trans World Airlines, Inc. Bon visionnage. Carl Icahn acquired control of TWA and took the company private in a leveraged buyout in 1988. Most people report what they observe, which is based on the heading of the boat. A sailing maneuver by which a vessel turns its bow into the wind, through the no-go zone, changing from a starboard tack to a port tack (or vice versa). (TWA), former American airline that maintained extensive routes in the United States and to Europe, the Caribbean, and the Middle East. Sep 18, 2014 · If COG = H, meaning you are moving the direction you are headed, then all of the standard vector triangle solutions for finding true wind will work fine. Feb 27, 2025 · True Wind Angle The True Wind Angle (TWA) is a crucial concept in sailing, representing the angle between the direction of the true wind and the direction in which a vessel is moving (its heading). The concept of true wind angle (TWA) is fundamental to sailing, particularly for optimizing performance and understanding the forces acting on a sailboat. May 27, 2025 · TWA did not originally stand for Trans World Airlines. Cruisers & Sailing Forums > Seamanship, Navigation & Boat Handling > OpenCPN Acronym TWS and TWD ? Sep 11, 2023 · What is Polar Performance Data? Polars, also known as a polar diagrams, describe how fast a sailing boat may go at different wind speeds (TWS) and at different angles to the wind (TWA). It refers to the angle between the direction of the true wind and the direction in which a vessel is heading. (TWA) was a former American airline that maintained extensive routes in the United States, Europe, the Caribbean, and the Middle East.
