My idea was to try my hand at making my own. There are a couple of ways to go about it, one is freehand such as I did with this torpedo boat.
Or, if it's too much work to sketch something, copying an image isn't a bad way to go either. In this case, my inspiration was Jane's 1898. This first edition of his long running naval annual works nicely as the book features Jane's excellent drawings, soon to be replaced by photos in subsequent editions. However, as all my Jane's are Arco reprints, the drawings actually hold up better than the grainy period photos.
I scanned the French pre-dread Jaureguiberry, also flipped it and printed out both images to copy the ship as seen from either side. Next I glued the paper to a basswood backing, created a base and using the outline of the photo copy, painted colors on the ship and the surrounding sea.
