Required Freight Rate (RFR) to transport one long ton of cargo 1,000 nautical iles in open water and to return in ballast equals $2.30. 15, 340, 000 Chignik Bay on the Alaska Peninsula is deep with an irregular bottom. It is an important area for salmon fisheries. The Bay is roughly ten miles wide by fifteen miles long open to the east. (See Figures 14-1 and 14-2.) Nakchamik Island lies in mid-entrance to Chignik Bay. The bight on the east side can be used as an anchorage, with twelve fathoms of water present and a sand bottom. The south side of the bay is a series of ridges forming a succession of headlands. The ridges terminate in vertical bluffs at the water, and are about 200 feet high. There are numerous water bays leading off Chignik Bay where protection is afforded for anchorage. Castle Bay, on the south, in deep with a mud or clay bottom and presents no known dangers. Most of the shore rises almost vertically from the water. Anchorage Bay, where Chignik is located, is about one mile by two miles in area and affords good achorage. The western shore is less precipitous, but backed by high land. Significant changes in depth and shore land may have occurred in the 1964 earthquake and have not yet been hydrographically re-surveyed. YA Fig. 14-2 (from C & GS 8502) A number of docks are available in Anchorage Bay, with faces alongside in excess of 60 feet and depths of 21 feet. Anchorages are available with good holding ground throughout the Bay, but there are intermittent areas with irregular ground. The five fathom line comes almost up to the shoreline and the ten fathom curve is within a mile of the shoreline as is the 100 foot mark. Within five miles of Chignik Bay there are water depths exceeding 40 fathoms. The diurnal range of the tide is 8.9 feet. A considerable current up to 1.5 knots follows the coastline but little current is observed in the Bay itself. Chignik has 151 inches of rainfall annually and winds are extremely variable. Gales are very frequent in the winter, with strong winds blowing through the mountain pass over Chignik Lake. The Bay sometimes freezes during a hard winter, but normally is ice free.
