The old Dungeon Magazine had an arc, maybe the Isle of Dread one, where the PCs traveled to a secret pirate base. There was a lot of description and unique places there.
Savage Tide had scuttlecove.
I really enjoyed reading Savage Tide back in the day. Was it ever collected or reprinted? Is the only option tracking down all the individual issues of Dungeon?
That would be "Operation Manta Ray" by Paul F. Culotta, in Dungeon issue #66.THere's a 2E Dungeon Magazine adventure set on a pirate isle. It includes a gauntlet.
One shady fellow has a peg leg. If you tread on his business turf, he will invite you to his office for a drink and a nice chat to smooth out the misunderstanding. If the PCs do not bend to his will, he will shuffle around to put the peg leg up and point his 'foot' at the PCs. "Ach, my bad leg, she pains me." He actually has a one-shot Lantan cannon (loaded with buckshot) in the peg that he will try to discharge into the group. Use Eldritch Blast or a dragonborn breath weapon for the mechanics. If the peg leg got wet recently, the powder will not burn but there will be an audible 'click' when he tries to set it off. His cohorts and subordinates recognize the quoted line as a verbal warning.
