Lake Testing

About a week and half ago, we packed up Nessie and traveled to Lake Arthur at Moraine State Park. We rented a gasoline powered boat to do some tow testing. The point of the tow testing (Recording the force required to tow Nessie at various speeds) was to find the drag coefficient of Nessie's hull. The testing went smoothly, despite some strong winds, and we were able to get some valuable data. We will be processing and incorporating the data in the design of the propulsion system (for the endurance event) and for future hulls.

We are currently neck deep in designing new systems and writing grant proposals. We're looking forward to finalizing designs and getting ready to build in January. I'll do my best to keep this blog current.

Here's some pictures from the lake testing. Enjoy!
