SimSail

SimSail is a free software for navigation, weather analysis, sailing route planning and performance analysis.

​

The strength of SimSail is to access a very large number of parameters. If current data exists, the wind received by the boat for the calculation of the routing will be the wind-surface resulting from the combination of the current and the wind, which corresponds to the reality.

​

The routing can be multi gribs of wind and current, multi road segments and multi-boats including compensated times from ratings.

 

SimSail can be connected to a navigation data system in order to analyse the performance of the boat and compare the actual navigation data with the routing.

​

SimSail is a simulation tool because it artificially reproduces the operation of a sailboat in its environment, using a computer program for purposes of study, demonstration or explanation.

  • Routing on multiple legs of route

  • Routing from the boat and/or to the active waypoint

  • Routing with multi gribs of wind and current

  • Imposed waypoint (pivot point on isochrone)

  • Integration of the current into all routing calculations (wind and boat)

  • Avoidance of coasts and barriers defined by the user

  • Avoidance of thunderstorms, weak or strong wind and high waves

  • Multiple routings by scan of variables (polar, wind – strength & lag, current – strength & lag, time of departure and several boats)
