small barges, yeah rgt

does anyone know how long the "small barge" is supposed to be? the stock Jap barge, i was looking at the .dp with DpEd 1.1 and the blueprint shows it to be 316 feet lond with a 30 foot draft and an approximite measurement of 60 ft abeam!
thats not small.
That would also explain why the ocean around it catches ablaze when strafed.
Anyone with any estimates? i was think around 21 feet long and a 5 ft draft
