The reua pratu nah or leading escort barges, i.e. the first barges in the line-up in the Royal Barge Procession (fig.), are Reua Thong Bah Bin (fig.), i.e. the first escort barge that opens the procession on the port side, and Reua Thong Kwahn Fah (fig.), the first escort barge on starboard. Reua Thong Bah Bin is followed by Reua Seua Kamron Sin (fig.), whilst the latter is followed by Reua Seua Thayan Chon (fig.). Here seen on the left, somewhat behind the barges described above, is a lesser escort barge, called Reua Dang (fig.), literally a ‘shield boat’, that accompanies and protects the other more significant barges in the parade.
