SOUTH ATLANTIC SAILING ROUTES (Cape to St Helena and Ascension Island)


This is the most common route for either 'Round-the-Worlders', or South African yachts en route to the Caribbean or Europe. The sail can be extremely pleasant as the wind will be off the starboard quarter once the trades are encountered.

The best time for the crossing is in the summer months.

A few suggestions:

Stock up with supplies very well in Cape Town, or other South African cities, as prices on the islands are high and stocks are limited. The direct route from Cape Town to St Helena Island is approx. 1700 miles, but it keeps you in a rather busy shipping route (Cape Town to New York).

A more northerly departure than Cape Town, with a southerly wind forecast, will keep one away from this shipping lane.

There are three seamounts close to a direct route that one should be aware of. Rough weather the area around the shallowest of these creates turbulent seas. These banks are close to each other, but the one of particular concern is Valdivia Bank with a least depth of 23m (rising out of depths of 5,000m plus). The others are 115m and 163m.

The position of Valdivia Bank is 25deg. 55'. S, 5deg. 30'. E. There are often many fishing factory ships and fleets in the vicinity. St Helena is free from offshore dangers if a reasonable distance is kept to sea. It can be rounded either way, but a northern approach to the anchorage off Jamestown will keep one in the windless lee of the island for the shortest period.

St Helena can often be seen on a clear day from about 70 miles away. There is a delightful medium wave communal radio station (1548kHz) that can be heard about 250 miles from the island.

The "Cape to Caribbean" Cruising Guide details the arrival at St Helena with photos, chart details, anchorages, immigration details, places of interest, etc. The guide continues in great detail to cover the other Atlantic islands and includes everything a cruiser needs to know about the route and making landfall in Brazil. It also supplies highly sought-after details on Brazilian ports and approaches, offshore islands, weather information, chart details, etc., right up to Tobago and Trinidad. The guide features good quality photographs and descriptions, chart references and diagrams to assist cruisers.
