Sailaway Sailing Simulator
There's a great sailing simulator called Sailaway. It's just your ordinary videogame - you can download it from Steam, and start playing. But it is more of a simulator than anything else. So I thought it might be useful in learning how to sail.
So does it? The short answer is yes.
It really mimics the sailing experience quite well. Also, the tutorials are at the same time sailing theory lessons.
But here, the same goes: it remains theory - until you get out on a boat and do it for real.
