Cornell’s Ocean Atlas: Pilot charts for all oceans of the world

Jimmy Cornell, founder of the Atlantic Rally for Cruisers, noonsite.com and author of the sailor’s bible World Cruising Routes has teamed up with his son Ivan to produce Cornell’s Ocean Atlas, an atlas of 129 up-to-date pilot charts aimed at sailors planning offshore voyages.

What is Cornell’s Ocean Atlas and how do you use it for voyage planning?

All sailors, even experienced ones, planning to set off on a shorter or longer offshore passage are concerned about what kind of weather they might encounter. The wise navigator will prepare for the worst eventuality but do everything possible to avoid it.

The main role of the Cornell’s Ocean Atlas is to allow you to check out wind conditions for every month of the year in any ocean of the world and thus gain an immediate overall knowledge of what you can expect at any given time of year.

Much of the information contained in the pilot charts that are in use today is still based on observations from the 19th century and, although they have been updated at regular intervals, the scarcity of reliable sources, inaccuracy of the observations, or the climate changes that have occurred over the years, have rendered some of the information shown on those charts to be now inaccurate.

To present as true a picture as possible of the actual conditions which prevail in today’s oceans, the pilot charts in Cornell’s Ocean Atlas are based on the most recent weather data gathered by a network of meteorological satellites over the last 20 years.

60 monthly up-to-date pilot charts of all oceans of the world show

  • wind speed and direction
  • current rates and direction
  • approximate extent of the Intertropical Convergence Zone, commonly known as the
    doldrums
  • the most common tracks of tropical storms
  • and the mean location of high pressure cells for each hemisphere

This is the kind of information you need even before you start actually planning a specific voyage, as it will allow you to decide straight away whether your plan is feasible. Once you’ve decided that it is, you can proceed to the next stage, and that’s to plan a voyage along a route that has the best chance of favourable sailing conditions.

And this is where the rest of Cornell’s  Ocean Atlas comes to your help.

  • Side by side with the monthly charts are 69 detailed charts of the most commonly sailed transoceanic routes. Even sailors with limited offshore experience will find it easy to plan a route that takes best advantage of the prevailing weather conditions at the chosen time of year.
  • Sidebars with tactical suggestions have been added to the months when most passages are undertaken.
  • The comments and tips on tactics, as well as weather overviews for each ocean, were contributed by meteorologists and routers specializing in those oceanic areas.
  • Furthermore, the Atlas also contains a comprehensive description of weather conditions in every ocean.

Reviews/Feedback

Cornell’s latest production certainly eclipses all his other productions with its ‘wow factor’. I am sure it will become, like his ‘World Cruising Routes’, a publication no long-range sailor wants to leave home without. —Sail-World.com

Seasoned voyagers know that pilot charts are one of the most valuable tools for passage-making. By employing the latest technology and weather information compiled via satellite over the last two decades and by quadrupling the number of roses roses on their clearly illustrated collection of transoceanic charts, the Cornells have not only updated a valuable resource but also substantially broadened it. —Cruising World, February 2012

This amazingly impressive atlas …. definitely fills a gap in the nautical book market. —Noonsite.com

This atlas is amazing. It is a game change for anyone planning a long voyage.
—Brenda Kelliker

Suddenly all my concerns on planning a voyage from 69ºN to 69ºS have been magically taken away as choosing the safe seasons and favourable conditions now looks so easy. —Magnus Holm

This atlas is a really clever take on Captain Maury’s original idea and I am sure that this is how he would have set about creating his pilot charts if he had invented them today. —Jon Fawcett

Congratulations for the excellent and outstanding Ocean Atlas. It is something that for a long time we blue water sailors have been waiting for!—Manfred Winter

Jimmy Cornell has sailed 200,000 miles in all oceans of the world including three circumnavigations as well as voyages to Antarctica and Alaska. As the founder of the successful ARC transatlantic rally, Jimmy Cornell is credited with having devised the offshore cruising rally concept. Thousands of sailors have fulfilled their dream of blue water sailing with the help of his books, among them the bestseller World Cruising Routes.

While working on his next book World Voyage Planner, to be published in 2012, he asked Ivan’s help in producing up-to-date pilot charts to illustrate the voyages described in the book. This atlas is the result of their cooperation.

Ivan Cornell

Ivan Cornell spent most of his childhood at sea and completed his first circumnavigation with his father by the time he was eleven. As an adult he has sailed thousands of miles as crew or skipper on a variety of boats in all oceans including two voyages to Antarctica. He has a degree in computer science from University College London and has worked for the last twenty years in the film industry.

Ivan applied his considerable skills as a programmer in constructing the website noonsite.com, the global source of information for cruising sailors. This atlas is the result of an ambitious program he wrote to process the data obtained by a network of meteorological satellites.

Ivan’s passion for the sea has never left him and he is currently sailing a yacht he built himself.
