Yes, 30W is usually the target at the equator and I think it will be the same again this year.During a N-S trans-equator route, all numeric routing will send the boats towards the African coast: models (whatever, GFS ECMWF etc) "see" more wind along the coast, but are particularly unable to locate the ITCZ and provide wind forecasts above what is to be actually found (mostly flat calm). The ITCZ extends North/South about 10-15° latitude along the African coast (read 500-1000 miles), only 2-3° latitude at 26-28°longitude, it often disappears westwards of 28°-30W but then it would be more difficult ot negotiate the SE trades while going south. There is somewhere an interesting article from Marcel van Triest (router of I do not know how many RTW racing boats) showing weather routing sending all the boats there (and eventually getting them stuck in place), final advice was never ever do that, even with Ultim and their impressive polars.
Once past the Cape Verde, they ought to get some west, heading SW with NE wind...
We'll see how it turns out this time
