I'd totally be eyeballing the Peddlers, so Pirate Ship would be a boon to me if my opponent were dumb enough to play it. Festival, Treasury, Forge and Bishop are all good support for Peddlers; the Festival and Treasury to pick up multiple copies and the Bishop to convert them to VP. Forge is good as well, to turn them straight into Provinces.
Now, looking at the game log I see that you won in part by using Pirate Ship. I still do not think it is a good play.
