Speed polars
Understand a polar and the polar percentage, generate your polar from your logs, import a .pol file, edit the polar and choose the primary polar.
- What is a boat speed polar?BeginnerA sailboat’s speed polar gives the target speed for each true wind angle and true wind speed (TWA, TWS). Reading the diagram and the table, theoretical polar and measured polar.
- Polar percentage (POL)BeginnerThe polar percentage compares the boat speed with its target speed at the same angle and wind. Computation, primary polar, recomputing sessions and interpretation.
- Generate a polar from your sessionsBeginnerCompute your sailboat’s measured polar from your NKE logs: choice of sessions, STW or SOG, measured cells, completion with similar reference polars, saving.
- Import a polar (.pol, .csv, .txt) or start from a referenceBeginnerAdd a polar to Avelsta from a .pol, .csv or .txt file, from the library of more than 510 reference polars, or by copying one of your polars. Accepted file format.
- Edit a polar and choose the primary polarAdvancedEdit a polar in Avelsta: drag the diagram points, correct the table, add angles or wind speeds, apply a percentage, overlay your sessions, save a version, set the primary polar.
- Free polar generator, no account neededBeginnerCompute your sailboat’s polar for free from your NKE logs, without creating an account: upload the files, choose the sessions, STW or SOG, polar completed from references.
