ASA 105: Skill 1, Chart symbols
1. Explain the chart symbols and conventions on U.S. nautical charts in accordance with the terminology of Chart #1.
Charts are comprehensive presentations of knowledge required by maritime navigators. One must be able to intemperate the symbols. Chart One is the most thorough.
Chart One shows chart symbols and explains the meaning of each. An abbreviated copy is printed on the back of Chart 1210Tr. We focus on USA symbols which are also common to most maritime charts. Chart One may be purchased from maritime publishers and/or downloaded to a computer or smart phone. A link to one source follows.

Nigel Calder's book: How to Read a Nautical Chart is an excellent reference as it provides additional commentary about symbols and their relevance and limitations.
