Ship Customization is a game feature which allows players to customize their own ships. Players may do this by visiting any shipwrightand choosing the "Upgrade" option, then choosing a ship to upgrade. Ships can have visually customizable hulls, rigging, sails, emblems, and special broadsides (hull ranks 4-6 only). Only Unlimited Access players are able to customize their ships. Also, only Medium and War Class Ships are able to be customized. Light Class Ships and Ships of the Line are unable to be customized. The following features are customizable/upgradable; however, all of them will cost gold and some of them will cost them some Ship Materials as well.
