Tacticat the online sailing tactical simulator just keeps improving. In the last week or so tides have been added to the program introducing all sorts of fun new realistic effects such as being swept on to the windward mark by the current.
There's also an action replay feature which I suggest you try if you want to gain a feel for the simulator. Go to the American Gold regatta from last night and click on where it says #6 REPLAY [SKIFF]. (You will see why I suggest this race shortly.)
I hope this works on your computer. For some reasons I have to click on the link, wait a few seconds, and then click on it again to get the Java applet to load properly. (Hey, I never said it was perfect.)
Once the applet starts you can click on F1 to see the full list of commands some of which you will need to control the view in the replay. Z and X zoom in and out. W controls different displays of wind. U controls display of current. You can left-click on the display to re-center what part of the race course you are viewing.
The race countdown clock is in the top left-hand corner. There are controls at top center to pause or slow the action, and a slide to fast forward at top right.
You will see the sailors chatting to each other before the start and during the race. The exchanges about ICISC relate to my Small World post from a few days ago. You will see some dude called Litoralis foul himself on my transom just before the start and then see him complaining at other boats that he thought were too slow at the start.
But note how that yellow boat aces the start, picks the correct side of the course, nails the layline (well almost) and leaves the fleet in his wake. As they say, "Even a blind nut can find a squirrel occasionally." Or something like that.
