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.

This year's event is on Saturday 27th June 2015.

• 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)
