Pirates of the Burning Sea (1.6) patch build. Also, you may see some never before seen ships on the waterways as eleven new ships will deployl. The ships setting sail are: Archelon, Cyclone, Dauntless, Mastercraft Couronne, Mastercraft van Hoorn, Monarch, Treason, Cruizer, El Dragon, Minerva and Trinidad.
In the latest developer log on the official PotBS website an explanation is given for these changes and the new ship additions. It's stated that a huge power gap between a level 50 in the right equipment versus other high level ships. To bridge this gap without nerfing the best ships in the game the stats on other high level ships will be boosted. This rebalancing act also presented the opportunity to add new ships. Captains should be wary. Your ship is always at risk from being hit with a stealth nerf when balancing occurs at a large scale. The ships and ammo change list is available after the cut, and there is a discussion taking place on the PotBS forums.
