Posey Advanced Racing Simulator is perhaps the flagship of the Posey line of simulators. It is a single-player racing game, with full sail controls and tactical information at your fingertips. Posey Advanced Racing Simulator has been steadily refined over the years, and the current release features updated appearances for the boats, and new features such as leeward gates to keep in line with the current state of racing in major North American regattas.
As the only major racing game without multiplayer abilities, Posey Advanced Racing Simulator relies solely on the Artificial Intelligence programmed into the computer-controlled boats to imitate the behavior of a large fleet. For the most part, the behaviors are convincing, with boats tacking, ducking, and reaching up for clear air at the appropriate times. However, with all boats essentially following the same set of AI rules and heuristics, one can get strange phenomena, such as an entire fleet preternaturally tacking on some psychic cue. Pre-start maneuvering is unrealistic, but this is a fault shared by all AI-based racing simulators.
Bottom Line: Still the best sailing simulator on the market for complete control over all aspects of racing in a large fleet, but the weak graphics and lack of multiplayer racing will mean that it will soon be supplanted by competitor products.
