VISIR® is a service providing optimized nautical routes in the Mediterranean Sea. The optimization regards total navigation time, taking into account safety of navigation. Both motorboats and sailboats are considered.


The computation of the routes depends on model forecasts of sea-state and wind.

The user can specify  departure date and time, departure and arrival locations, vessel type, and other parameters. 

The routes are displayed on top of the forecast fields, superimposed on a Google-map. 



Detailed information about the model on which VISIR®  is based can be found in the publications:
