I've downloaded and played virtual skipper
(latest version, think it's 7). It's a free download and you can play all the courses for free, think you only have to buy it too compete online? not sure about that.
It's actually pretty decent. Graphics are servicable (it's not the latest greatest half-life/unreal engine game
but they're ok still).
I pretty much used it as my learning
how to sail program, you can heave-to in the game
and it's good for learning wind
angles etc. Obviously sail handling is a bit easier then in real life
, but it's definately worth downloading and having a go.
