Chasing underwater gold
Designing, building and racing a human-powered submarine is a goal that can only be achieved by a team of dedicated, enthusiastic and motivated individuals working together, sharing complementary knowledge and skills. The team is drawn from all faculties of the university. Engineers design the machine, Makers build it, Divers get it moving, Programmers keep it on course, and Management makes it all happen.

A whole new concept in submarine racing
Our Workhorse coming out of Retirement
Human-powered submarine racing is a unique engineering and sporting challenge. Essentially an underwater bicycle, the flooded submarine enclose a scuba diver who uses their muscles to provide propulsion power. The submarines, from universities all around the world, are run against the clock at races in the UK, US, France and Germany. The HSRW Submarine Team has taken part in a race every year since its inception in 2012, holding its own against some of the world's biggest universities, bringing home trophies for design and medals for performance.
Each team consists of following roles:
The fourth HSRW submarine was a complete rebuild of the first one. Only the hull remained of the original Rivershark. The propulsion this time was a pair of turtle or penguin-inspired flapping twisting foils.
The third HSRW submarine was designed primarily with manoeuvrability in mind. Taking inspiration from the knifefish, Trichitala was driven by three ribbon-like undulatory propulsors.
The second HSRW submarine, Inia was designed to be an acceleration specialist. Propelled by a chain-driven counterheaving mechanism, Inia's low aspect ratio tails provided the high thrust required to accelerate over the first part of the racecourse.
The first HSRW racing submarine. Rivershark 1 was propelled by a pair of counterheaving fins inspired by the wing-like tail of a sailfish.
