Wrangell Narrows lies between Mitkoff Island on the east and Woewodski and Kuprenof Islands on the west. It extends in a general Northerly direction for 21 miles near the East end of Sumner Strait to the East part of Frederick Sound. The channel is narrow, with strong tidal currents and dangerous ledges and flats. But it is marked with lights, beacons and boys, which, with the aid of the chart, renders navigation fairly easy. Still, currents can run between 4 to 5 knots up to a 6 to 7 knot current during the spring and tropic tides. Thus, you should be able to understand why we are waiting for the currents. Oddly enough, you need to time yourself as you can catch a ride on part of the narrows finding yourself fighting currents at the other end.
