N.B.: Set your course so as to arrive as the tide changes
at your destination. Thus, at Cap-à-l'Aigle, the current
is still declining about 2 hours after low tide. If you take
the north channel past Île d’Orléans or
the St-Roch passage, you can gain up to one hour. In the case
of a boat travelling at more than 10 knots, leave at high
tide at Quebec City.
