SimSail

SimSail is a free software for planning sailing routes. It allows to find the best route by visualizing the conditions encountered in navigation.

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.
