You are correct.  The 2010 rules and regulations do not require a spare paddle.  The rule has, however, changed.  After reading your post, I wondered if I was getting senile, so checked the rules again.  I went back to the rules for 2006 and there in paragraph 7-Canoe Equipment- it read "An extra paddle or anchor (with not less than 15 m of rope or chain)."  I don't understand how an anchor is the equilvant of a paddle.  Maybe you throw the anchor out and then pull yourself forward.  Or do you anchor and wait for the wind to change?
