Tanaga Pass

Tidal currents commonly range between two and three knots in the pass.

From the U.S. Coast Pilot:[1] "Depths of 50 fathoms or more can be carried through the pass by keeping 6 miles (9.7 km) off Cape Amagalik, Tanaga Island, and 3 miles (4.8 km) off the Delarof Islands.

"The direction and velocity of the current is radically affected by the land areas and the banks.

During observations made 4.5 miles (7.2 km) southwest of Cape Amagalik, the current was rotary, turning clockwise, and followed a definite pattern.

A minimum current averaging about 0.8 knot sets north to northeast."
