Canadian tide and current tables, 2011 Ottawa - Ontario : Fisheries and Oceans Canada. Annual 2011 Tide and current tables predict the times and heights of high and low tides, the times for slack water, and times when currents will be at maximum velocity. Tide tables are used to obtain the depth of water under the keel or over a shoal, for anchoring, and for deciding when to beach a boat. Current tables ensure safe navigation, especially when under sail, navigating narrow passes or channels with strong currents, or the wind is against the current.
