Another great book along the same lines is "How to build car dioramas" by my modeling bud Ken Hamilton.It is out of print now but he has given me permission to use it for teaching purposes.Many marine diorama scenes could include harbors or docks that could contain any number of things worth building other than just the ship model.Wharves,sheds,figures,barn siding,bricks and masonry walls etc...etc..whatever your imagination can come up with. That is the fascinating thing about diorama making it can encompass such a wide variety of subjects and modeling techniques.
