Description
Interestingly it has been constructed on a conical projection which means that Great Circle tracks can be plotted as straight lines rather than curves
The shows the main trend of contours, lits of ice, magnetic variations and keys routes as identified by D M Street
On the reverse are notes on the routes and small wind rose charts, with accompanying charts showing excessive wave heights and storm frequencies for the months that yachts cross the Atlantic, April to July and October to December
This chart will be an important companion for Atlantic Yachtsmen on passage and an excellent source of planning information
