This isn’t the first sailing ship I’ve designed with an unusual rig, and it probably won’t be the last. In fact, this isn’t even the worst offender in my collection. This one, at the very least, is historically plausible, and remarkably similar to a ketch rig, aside from the placement of the masts. However, to anyone who might quibble about the term “sloop-of-war,” I am aware that the term is usually used to refer to a fully-rigged ship (three-masted, by definition) that is too small to be a rated frigate. That being said, bomb vessels were historically classified as sloops-of-war, and prior to the 19th century, three-mast bomb vessels were unheard of, with most being rigged as ketches.
This two-masted sloop-of-war has a rig that is hybrid of a brig and a polacre, the latter of which is a three-masted ship with square sails only on the foremast. I suppose that makes this ship a “hermaphrodite brig,” but this particular configuration isn’t common enough to have its own name.
