The vessel was named for Rock Shoal Bay, which connected the Charis Sea to the Throat.
In the Battle of Darcos Sound, it engaged a Corisandian ship by crashing into it, bringing down its mast. It then staggered directly across the path of another Corisiandian ship, the Confederate, which hit its side. Rock Shoal Bay began to fill rapidly, leaning against the other vessel. Around thirty of Rock Shoal Bay's rowers were killed by the impact, and dozens injured. Their companions struggled to pull them out of the water as their ship began to settle. While the Charisian gunners fired a deadly salvo of grapeshot down the length of the other ship's deck, the Charisian Marines charged across. (OAR)
