SailSim is dinghy/yacht sailing simulator that can be used as a learning and teaching aid for sailing.
SimSail works best with the iPhone 3GS but will also work with any iPhone or iPod touch. With an iPhone 3GS your phone becomes a virtual dinghy that you can steer as you would a real dinghy. The sails will automatically adjust to the correct position for the point of sail.
NB - Please allow SailSim to access your current position - this enables the inbuilt compass and allows SailSim to know it's orientation.
iPhone 3GS - with this hardware, your iPhone turns into a sailing boat. You can set the wind direction and then see how changes in boat heading effect the set of the sails, centerboard and boat speed. As you turn the iPhone (boat) the wind direction stays constant relative to the boat and the sails adjust and change shape as they would do in real life. This can be used to demonstrate key principles of sailing to students. You can override the set wind direction with a touch of the screen as explained below. To set the wind direction, press the i button, point the iPhone into wind, hold it there and press 'Done'.
iPhone 3G/2G/iPod Touch - as this hardware does not have a compass, you have to manually tell the SailSim where the wind is blowing from by touching the screen. Using the mast as the center point, touch the screen around the boat to set the wind direction. The wind indicators will show you where the wind is blowing from.
SailSim shows you: o Boat Heading o Centerboard (Daggerboard) position o Boat speed for each sail angle o Boat tack o Point of sail o Wind direction - as compass direction and arrows o Relative wind position (as you would see on an instrument)
