I recommend this book very highly.
The language is a bit rougher than is the salty talk customary in sea stories by genuine British authors. I wonder if Lambdin chose "Lewrie" as his hero's name because it resembles lurid and lewd, which Alan is, although he's not a scoundrel as well. This is a physically bigger book than the other Lambdin pb's I've read, thanks to the customarily expansive McBooks Press edition (i.e., larger type and better paper than the stubby Fawcett Crest/Ballantine editions).
