The Reua Asuravayuphak is a large escort barge, with the figurehead of the demon (asura) Vayuphak (fig.), used to accompany the true Royal Barges during the Royal Barge Procession. It has a crew of 30 rowers and 2 helmsmen, besides a trumpeter, an officer, etc. The oarsmen wear pink trousers, a dark-blue to purplish shirt trimmed with gold, and a red Malabiang-helmet, whilst the oars are silver with a red handle. It sails on the port side of the procession, to the opposite side of Reua Asurapaksi (fig.). From afar, both the Reua Asurapaksi and Reua Asuravayuphak escort barges are confusingly similar to the Garuda escort barges Reua Krut Heun Het (fig.) and Reua Krut Tret Traichak (fig.), and can from a distance best be distinguished by the fact that the bird-like figureheads (fig.) of the former two barges have their arms in a downward pose (fig.), whereas the arms of the figureheads on the prows of the Garuda escort barges have their arms held up (fig.).
