To be quite honest, I have yet to have laid eyes upon the skeletal sloop in person, but I had an idea that crossed my mind.
Name: The KegRunner
Ship Type: Skeleton Sloop
Concept: Unlike other skeletal ships who otherwise sound their war horns when they arise from the depths, these keg enthusiast would arise with a chorus of hissing wicks. Their ship would have an Ashen style overlay on the skeletal vessel and within the hold would be a plethora of kegs. These vessels would sail up upon a player's ship and when within range, their bell would begin to ring as they ram the hull, igniting their kegs as they go out with a bang. They would be able to be countered, of course. A marksman would be able to pick off a keg on their middeck next to their mast, igniting their explosive cargo before they can even get within range.
I think these could also be useful in skeleton fleets. Should you be low on cannon balls or kegs, you could overpower the skeletons aboard and use the sloop to powder keg the skeleton galleons, wiping out most of their crew and punching holes into their hull.
