As a matter of fact, late in VS 6.8 the default version of Ilan's sailboat had several crude animated pilot figures (looked like naked manikins). Among these was a figure sitting on the weather foredeck. Upon tacking, that figure rose, walked across the deck, and resumed sitting on the new weather rail. Others cranked winches, and of course one steered and waved. This was around the time Ilan first introduced the pilot.x function. Unfortunately, VS7 superceded that version, and instead had a revised sailboat with the sole default pilot we see today.
I surmise Ilan would remember that sailboat crew, and might provide insight on the functionality.
