This from the Nanaimo Bulletin and thanks to a tip from the ARRL:
The Nanaimo Amateur Radio Association will be participating in the July 26 Great International World Championship Bathtub Race and thanks to an online portal at the association’s website the public can watch the race progress in real time. Two of the bathtubs are going to be outfitted with AGPS units which will relay information to an interactive map. The Nanaimo hams will also be operating a special event station during the event.
