See the orange looking figure. That is a catamarran that was on the course during swim workouts prior to the race. It is a "coffee bar" where you could hang off the edge of the pontoons and have "kold or hot coffee" (Kona coffee) or kold water or gatorade. You just hang around bobbing in the water chatting w/everyone and then you take back off to go further out or back in to the shore. This was located 700 meters from the start.
