today... day 3 of sitting at the 22' for 6+ hours videotaping human powered submarines at the bottom of a tow tank. I have been bouncing back and forth between my Green Flying Force and my Excellerators w/batwings. They have been getting lots of attention and questions, most have been answered by me swimming along side the subs at 3-4 knots clocked speeds for 30+ meters (the camera cord limits my speed and travel distance). We have some subs doing well over that, its a really interesting event, I hope to bring some photos in the next couple of days, more info on the event can be found here
