Demolition Rafts are packed with explosives that blow up against enemy ships, Docks, land units caught in shallows, and anything too close the shore. Both the Demolition Raft and the Fire Galley were introduced in The African Kingdoms to make the naval battle in the Feudal Age more versatile. Before their introduction, the only military vessel available in the Feudal Age was the Galley, so battle was very linear. Demolition Rafts are available to all civilizations except for the Koreans.
