Yacht Racing Game

I made this game for all sailors.
Easy way to control. Tap to tack, long-press to change the direction to where you want to go. That's it.
You can change the setting of environment and boats as you need.
This game can be helpful for beginners who will start yacht racing.
【About Sailing】
-Sailing is a sport advances by wind power.
-When a yacht is travelling upwind by 45 degrees, it is sailing ”close-hauled”.
-When a yacht is travelling diagonally to the left towards upwind, it is sailing ”starboard”.
-When a yacht is travelling diagonally to the right towards upwind, it is sailing ”port”.
-The maneuver of turning between ”starboard” and ”port” is called ”tack”.
-Make a series of tacking moves in a zig-zag fashion, and lead your yacht to the finish line!!
-New courses have been added.
【About "Right of Way"】
-Starboard yacht has the right of way.Boats on a port tack shall keep clear of boats on starboard tack.
-If you meet with starboard boat when you are on a port tack, you have to tack or bear not to hit.
-When a boat is tacking it shall keep clear of boat that is not tacking. You need to check whether there is no ship around you, before start tacking.
-If you hit another ship without your right of way, you will be "DSQ"(disqualified), which means "game over".
(*These are simple rules for game.)
