You're quite right that the two board format certainly isn't new on some fronts, but for the Olympics it's my understanding that it would be in the sailing arena. Clearly Joe's thoughts coincide with this approach, and as he notes, the use of only one sail makes things fairly simple and inexpensive. All wind ranges would prove viable, and this could be accomplished with a minimum of pumping. Contrary to FE, the use of a carbon boom would polish the package off, to include possibly a choice of two fins to cover both boards (a weedfin could be a choice in some venues). Very creative, flexible and results focused. The potential conditions experienced in races can mix things up, but that's what defines the total Olympic athlete, and separates the outcome from a specialty racing formats like formula or real light wind longboards where body types often bend or skew the results.
