By Gary Dierking Steering is one of the great challenges of proa design. The one who finally designs a steering system that a) shunts easily, b) controls the canoe both while at speed and while stationary during a shunt, c) is hydrodynamically efficient, d) is immune to underwater hazards, and e) is simple and foolproof, will have discovered the proa “holy grail”. Could it be that the Pacific Islanders have already invented such a wondrous device? My first experience with a steering oar was not auspicious. In Coast Guard boot camp I managed to talk my way into steering one of the big whaleboats used for training and racing. We must have had all the strong guys on one side as my best effort was not enough to prevent ramming one of the other boats; causing an automatic disqualification and my demotion to rowing guy. It took quite a few years before I realized that a steering oar is much more than a rudder. If I had used the oar function I could have avoided the collision.
