Captain Barnaby has been at Rimmington for many years , and the source I found suggests he was already associated with the route in the early RuneScape era, while one forum discussion says his Rimmington docking was added more recently, around 2018–2019.

What the sources say

  • A RuneScape wiki entry lists Captain Barnaby’s original release date as 30 April 2002.
  • A RuneHQ entry describes him as the sea captain who takes players from East Ardougne to Brimhaven.
  • A player discussion specifically claims his presence in Rimmington is “fairly recent,” estimating 2018–2019.

Best answer

So, for Rimmington specifically , the best available answer from these sources is roughly 7–8 years as of June 2026, though that date is based on forum recollection rather than a formal patch note.

Note

If you want the most exact answer, the next step would normally be checking an official update log or patch history for the Rimmington travel option, because the sources above do not give a precise release date for that location.
