4. Modern Ship Anchor Plaque

This Navy-style stockless anchor is the type used on all modern ships and, at 3 tons, it is typical of those carried on 8 - 10,000 ton freighters. A usual rule of thumb provides that a vessel's anchor chain should be three times the depth of the water in which she is anchored: this chain usually weighs about 100 pounds per foot. Provided by the Army Corps of Engineers.
