Wikipedia states it could be 30 km/h in the best possible conditions. He can maintain that speed as long as he remains in the trade-winds. Apparently the record is 41 km/h but only for a short moment. Otherwise it depends on the winds. Apparently, the average speed of the Trade-winds is about 25-30 kmph. Navigation in the Doldrums and the Horses latitudes is usually very slow since the winds are weak.

Anyone knows the speed of the Westerlies and the Polar Easterlies ?
