The Innovation Award was won by Sussex County Techni- cal School from Sparta, New Jersey, with UMPTYSUATCH-8 for their use of a Schauberger's turbine propulsion system, utilizing a 14-ft. lathe as part of their manufacturing process and having a rear-facing pilot utilizing a forward-looking GoPro camera system for steering. Second place in the In- novation Award category was awarded to the University of Washington with KNOTTY DAWG. The boat was built using a two-school collaboration to construct the wooden hull, and the craft had dorsal and ventral fins with ballast to prevent torque roll and a central chassis chain geometry. Third place in the Innovation Award category went to Rhein Waal University of Applied Sciences' Rivershark Mod 1 for having a sonar-based autopilot system with artificial lateral line speedometer and a mirage drive outboard propulsion system. AC Mosley High School with TRIGONUS was given an honorable mention for having a cost-effective and time- efficient hull construction. Their boat cost $350 (without scuba) and was assembled on site at Carderock after the competition began. The Absolute Speed winner was SUBLIME, a one-person, propeller-driven submarine from Hernando County Schools, Springstead, Florida, with a speed of 5.77 kt.
