Query: Sea Wolf

I thought there was wonderful character development. London made me feel as if I actually knew the people as well as he did. He used fantastic visual imagery and if I closed my eyes I could see the action take place. He used many sailing terms I was unfamiliar with and to more thoroughly enjoy the book I would suggest any reader brush up on sailing vocabulary and parts of a sailing vessel.
