Check Faveral's ships and accessories. Also the various pirates that are around. Nothing at DAZ 3D... High Seas Adventures for S3 at PoserPros has one, and if you have a freebie pick left, it's in that list. There's a spyglass and sextant in Faveral's nautical bric-a-brac set. The Aurore Accessories includes a ship's boat, not really right for Swallow or Amazon, but maybe usable in the background.
