Yes, I did think about using my LOJ fisherman's boat, and may well redo the scene with that and other accessories, barrels, Amphora, crates, on the wharf, but not having much time this week, I decided to go ahead on do this quick set up whilst the idea was with me !
But being on the wharf, and a boat available to these refugees, with Vesuvius in the background about to blow, time is tight for these folk, who are cutting it fine in leaving.
Of course with your Roman Galley Robin, you could do a diorama of Pliny the elder mounting a rescue mission ! Though as history will tell you, it didn't end too well for him, dying on the beach, overcome by fumes I think !
