eSail Pro is the latest add-on for eSail Sailing Simulator. eSail Pro takes the simulator to the next level with advanced instruments, a refillable fuel tank and more. The new instruments include a fuel gauge which also shows engine hours. The tank size is 15 gallons and can be filled at Port Fogerty on the South of the main Shearwater Island. There is also an new wind indicator, showing true and apparent wind speed/direction. Below this we have a new autopilot instrument, providing incremental controls and the ability to set the autopilot to the wind. This is very useful when racing, but is a convenience in general sailing too. eSail Pro enables you to try more advanced sailing such as mooring under sail. And we have also added a Mooring Sandbox where you can set wind speed and direction to practise your mooring. This is supported by two new tutorials covering more advanced mooring techniques and how to get the best out of eSail Pro.
