Coastal Waters of Southeast Alaska and British Columbia

The IHO defines the limits of the Coastal Waters as follows:[1]

• On the Southwest. A line running from the Northwest extremity of Cape Flattery to Tatoosh Island (48°23'N) and thence to the Southern extreme of Bonilla Point (124°42'W) in Vancouver Island.
• On the West. A line running westerly from Black Rock Point (50°44',5N) in Vancouver Island through the Scott Islands in such a way that all the narrow waters between these islands are included in the Coastal Waters, thence to Cape St. James (Southern extremity of Queen Charlotte Islands), through this group in the same way, then from Cape Knox (54°10′N 133°06′W) Northward to the Western extreme of Langara Island and on to Point Cornwallis (132°52'W) in the Prince of Wales group, thence along the Western shores of this group, of Baranof, Kruzof, Chicagof, and Yakobi Islands, so that all the narrow waters between them are included in the coastal waters, and, finally, from Cape Bingham (58°04'N) in Yakobi Island to Cape Spencer (58°12′N 136°39′W).
