Advanced Ship of the Line are a special limited edition improved vessels of the Ship of the Line class ships. They were first mentioned in The Mystery of The Stolen Design which is a play that revolves around the search for the designs after they were stolen and taken to Sir Carlos Clemente, King of Spain. They were designed and constructed by Daggerpaine Industries on the request of King John Breasly. Twenty of the ships were built but five were lost in a battle agaisnt Spain because they were vastly outnumbered but managed to win anyway because of their sheer power.
The designs were drafted, but stolen the next day before construction could begin. Lawrence Daggerpaine hired his two friends, Jack Pistol and Prince Edgar Wildrat of england, to help him retrieve the stolen designs after they came to the factory in seek of a reward for completing a quest Lawrence gave Jack.
After retrieving the designs Bill Plunderbones had already completed the construction of the ships using his memory of the designs to create the ships. He sailed the ships to England with the help of some Gen. Of Peace guildmembers. Once they arrived Jack and Edgar were each given a post as captain aboard one of the ships as well as some other people. They fought back the Spanish Armada and were victorious.
The Advanced Ships of the Line are now scattered and used by their owners but several still belong to the Royal British Navy. The Navy owns eight of them, including the ones by owned by King John Breasly, Lord Matthew Blastshot, Captain Robert and Prince Edgar Wildrat. The others are privately owned by people who were rewarded for aiding England in the battle but most of the owners are still willing to use their ships to aid England again if necessary.
