How to obtain
The Royal Ship-of-the-Line will be one of the random ships which can appear for purchase from the bases of the pirate AI characters Anne Harlow or Jean La Fortune after reaching a trade agreement with them.
Alternatively, the player can construct the Royal Ship-of-the-Line after obtaining the legendary ship specialist item Sir Milfoy Credenza-Belfry-Guscott, HM Ship Architect and placing it into a Harbourmaster's Office within range of their shipyard. This item can be rarely obtained from Rescue Expeditions, or from completing quests for Carl Leonard von Malching, or as flotsam from destroying ships belonging to Carl Leonard von Malching.
