I heard from Aaron that competitive paddlers at Macritchie Reservoir polish their kayak hulls. A member of the public saw this happening and lodged a complaint. Paddle Lodge at Macritchie Reservoir now has to send a report of some sort.
Tsk tsk. Horrible lah these people. Risk poisoning the reservoir for what? 0.0001 knot more? I'd rather have unpoisoned drinking water.
