Ramming moulded naval architecture & tactics in the 1860s / 70s. Most historians think this an error. Rams, they argue, could hardly ever happen. Film shows how they could.
My view of the collision at sea of China Coast Guard 3104 and PLA Navy 164 in the vicinity of Bajo de Masinloc in Zambales, Philippines.
Before this, the Chinese navy and coast guard ships nearly collided twice trying to outmaneuver BRP Suluan of the Philippine Coast Guard.
