Sven Yrvind, sailing a 17-foot (5-meter) engineless boat, explains his strategy for crossing the Doldrums without motoring through them.▶ 2:07 His core solution is timing: crossing the equator in February or March rather than July, because the ITCZ and Doldrums shift north and south seasonally, and the February–March window places the belt at its narrowest and most favorable position.▶ 4:56 He references a 1950s British Admiralty sailing ship routes publication — route 1007, covering the Channel south around Cape Horn — as his primary planning tool, supplementing it with pilot charts that show the full annual cycle of wind and current.▶ 3:57 Yrvind has crossed the equator three times before, in 1969, 1973, and 1979, and says he now understands the African monsoon's influence better than on those earlier passages.▶ 5:14 His planned route calls for stopping at Periapolis before proceeding to Argentina's Río de la Plata, then departing south toward Cape Horn in December or January.▶ 6:27 Crossing in March instead of July saves roughly 600 miles of eastward deviation.▶ 7:26 Timing the equatorial crossing to the seasonal minimum of the ITCZ eliminates the need for an engine on a small sailboat.
