Kobune

The first real useful ship in Rokugan. Methods of curing and treating timber that allowed hulls last longer. These advancments were made on barges and dugouts and the Kobune were born. Later advancments were using pitch to seal the seams between the planks and seasoning woods so they could be made into properly shaped hulls. Most advancements were made by the Mantis Clan.
