April 2015

• Algorithm extensions to support extreme wind conditions (or long distance offshore races) where the wind may shift within the full 360 degree range during a leg of the race.

March 2015

• Support race board simulation during a live race
• Improved polar data mining including polynomial regression models for beat and jibe angles and speeds dependent on wind speed

February 2015

• Performance improvements due to parallelization of course computations
• Caching of race board simulation results for each leg of a race

October 2014

• Simulation is being integrated into the race board (see What's New in Sailing Analytics)

August 2014

• Accuracy of optimal course calculation has been improved
• Streamlet motion is now calibrated to physical reality on large zoom levels of the map

April 2014

• Wind is visualized using animated streamlets based on a swarm of particles which locally follow the wind

September 2013

• Windbot based on RaspberryPi to construct real, spatially resolved wind vector fields from wind measurements

June 2013

• Optimal courses shown as "Omniscient" are determined by an heuristic search algorithm greatly improving accuracy and runtime performance
• Sailing angles are represented with full numeric accuracy
• Water current is taken into account
• Support up- and downwind legs
• 1-Click Simulation simplifies the user interaction
• Race course map for Kieler Woche and Travemuender Woche

March 2013

• What-if simulation comparing sailed GPS-track and simulated course with changed locations of turns for answering questions like: would it have been advantageous to do the second turn a bit later?

February 2013

• Strategy Simulator becomes a part of SAP's Sailing Analytics suite

December 2012

• Polar diagram chart is available
• Multiple boat classes are supported based on polar diagrams in tabular format provided as CSV-files
• Several wind visualization approaches are supported: arrows on a grid, as well as, heatmap combined with bearing lines (either grid or integrated across race course)

June 2012

• First upwind-only prototype of sailing simulation is available
• Optimal courses shown as "Omniscient" are calculated with an implementation of Dijkstra's algorithm on a rectangular spatial grid
• Wind is visualized by arrows which scale with wind speed
• Race course definition with 2 mouse clicks for start and end
