Both "The Harbormaster" and "Auctioneer Assistant" are very minor characters, and "Jack Sparrow's dinghy" is a minor vessel. They all wouldn't be anything else but stubs to this Wiki as they had very minor roles in their single appearances.
Ah, I gotcha. Well, no worries about that. I've dealt with these issues and far worse (i.e. cpu shutdowns, internet problems, etc) to where I plan ahead. I know, it's a bit drastic... but hey, gets the work done.
