Welcome to the European International Submarine Races, where teams of university students are challenged to design, build and race human-powered submarines against the clock on an out-and-back grand slalom course. The concept combines engineering design challenge with technical skill development and sets them in a unique and exciting sporting competition.

Design Rules

The teams’ vessels are submarines in every sense of the word, except for the watertight bit. Here are the rules they must design and compete by.

Qualification

Qualification Round

The first stage of eISR 2024 has begun. There are only 12 spots on the starting line at the eISR. To qualify for one of those spots, teams have to complete a set of requirements to the satisfaction of the judges and race staff. The ‘lights’ in the figure to the left will light as teams complete the requirements. When all lights are ‘lit’ (light in colour), the team has qualified. The stages are:

  1. Registration: Indicate intent to compete and pay registration fee.
  2. Spec: Upload one-page engineering specification.
  3. Report: Upload engineering design report.
  4. Photos: Upload zipfile of photos of completed submarine.
  5. Video: Upload video of submarine underway, under water.
  6. Divers: Evidence of diver qualifications & experience.
  7. Fees: Pay final race fees.
  8. Qualified: All conditions fulfilled. Ready to race!

The Teams

It takes a dedicated team of engineers, athletes, logisticians and sponsors to field a racing submarine. Come meet the students who are readying their underwater steeds for the real-world challenge of launch, race, repair and upgrade which is the eISR.

Past Races

The eISR turns 12 in 2024. There have been some spectacular teams and machines over the years. Speed demons and innovative designs have taken up the challenge. Some have done well, even set a world record, while others have, well, brought up the rear. Here are their stories.
