Chart 100 North Atlantic Ocean Passage Chart

At a scale of
1:7,620,000 this chart covers the North Atlantic from Brazil to Newfoundland
and Gibraltar to the Caribbean. It has been constructed on a conical projection
that means that Great Circle tracks can be plotted as straight lines rather
than curves. Chart 100 shows the main trend of depth contours, limits of ice,
magnetic variations and keys routes as identified by Donald M. Street Jr.In the enclosed booklet
are pilot charts showing winds, currents and wave height frequencies with
accompanying notes on favourable route timings and hurricane risk. Chart 100 is
an important companion for Atlantic yachtsmen on passage and an excellent source
of planning information.



For this edition the
magnetic variation curves have been replaced by a web link directing sailors to
up to date information. The monthly diagrams indicating meteorological seasonal
variations have been changed from March, June, September and December to May,
June, November and December.
