The GWN results thread has been hijacked by a discussion about lane bias and best race courses, so I thought I'd start a separate thread.
I'm an advocate for the Welland course. As part of the current testing, a depth profile was prepared. The University of Guelph researchers found that (at the finish line) that the canal reached a depth of 12 metres 22 metres from the west bank and then was consistently 12 metres deep across the course until 12 metres from the east bank.
Having raced in Sudbury many times for both dragon boat and flatwater, I can't believe the suggestion that the Lake Ramsay course is better, particularly from a depth consistency and spectator perspective. I've seen them pull the course in too close so that the inside lanes are lanes of death. And if they move it out, it is no good for spectators. While wind can be a problem in Welland, on Lake Ramsay you can have the combination of wind and waves.
