The raft race is held every year in June/July as part of the Edinburgh Canal Festival. The race takes place in the Lochrin Basin at the end of the canal in Fountainbridge.

Hacklab has entered every year since 2011, (except during COVID, 2020-2021).

This years raft race will run in the Edinburgh Quay Canal Basin from 2.30-4.30pm on Sat 18th June 2022.

• We're getting too good at this. We should aim for the Daftest Raft award and provide maximum entertainment value.
  • Carry lots of people (at least 6, 8-10 would be ideal). This provides entertainment value, and allows more Hacklabbers to take part.
  • Carry passengers (more fun, at doesn't give us the unfair speed advantage of lots of paddlers).
  • Articulated raft, multiple segments tied together (easier to transport, can be scaled up to more people).
  • Submarine.
  • Simple raft, outrageous decor. (e.g. look like an aircraft carrier, or a giant shark)

<sarcasm>This year's raft race was done fully online because of covid reasons. Each team 3D scanned and measured the physics properties of the materials they would have used in building their raft. The materials were assembled into a raft inside of CAD software before being simulated inside of a Computational Fluid Dynamics/Multiphysics program.</sarcasm> https://www.facebook.com/permalink.php?story_fbid=3507286949301403&id=237399276290203
