UW Human-Powered Submarine Team in International Competition

2018 Knotty Dawg
2016 Races in Gosport, UK
2015–2016 UW HPS Team

It’s really neat to have the team gravitating to the use of wood again in this year’s hull, having built this cool new wooden submarine in partnership with the Northwest School for Wooden Boatbuilding.

The coolest thing is the fact that we took this really big goal of having a two-person submarine. That was a big ask. But because it is such a greater engineering challenge, we learned a lot more from it.

International Submarine Races

The UW's entry in the first International Submarine Races competition in 1989 was built at APL-UW and the team was comprised of Laboratory scientists and engineers, and UW students. Since then, the team has been an active club in the Department of Mechanical Engineering.

APL-UW Principal Engineer Andy Stewart serves as the team's faculty advisor, so many of the design and build activities have returned to APL-UW facilities. Taking inspiration from the 1989 sub that was constructed of spruce strips coated by a fiberglass shell, the UW team collaborated with the Northwest School of Wooden Boatbuilding on Knotty Dawg — a two-person sub with a hull made of red cedar strip planking and fiery khaya veneer.

ROV Team Design + Build

The ROV team got me an internship this summer. It’s taught me a lot of hands-on stuff that I just don’t think you get in school.

Our goal is to do research. Our goal is to create something that’s helpful not only for ourselves and our own missions, but for the university as a whole… it’s awesome just how into it people get. There’s something magical about mixing water and electronics — making a robot that goes in the water.
