Imray Chart 100 is an important companion for Atlantic yachtsmen on passage and an excellent source of planning information.
This new edition covers the North Atlantic from Brazil to Newfoundland and Gibraltar to the Caribbean and has been constructed on a conical projection that means that Great Circle tracks can be plotted as straight lines rather than curves.
For this edition the magnetic variation curves have been replaced by a web link directing sailors to up to date information.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.
The chart comes with a booklet of pilot charts showing winds, currents and wave height frequencies with accompanying notes on favourable route timings and hurricane risk.
