Ports and Passes is the most complete reference guide for tides and currents along our beautiful coastline. Ports and Passes is a popular tide and current book covering the areas from Olympia, WA to Prince Rupert, BC. This annual publication has quickly become a favourite among boaters in the Pacific Northwest. For each tide or current station there is a corresponding reference chart and a list of services and amenities - most within walking distance of a marina. Ports and Passes uses the more familiar 12-hour clock and is corrected for Daylight Savings Time.
