that's a good idea - and I've read it's something scientists have worked on. (If you're really interested, see a book called "The Urban Whale". The major problem of course is communication - how do you say "dive! dive!" in right whale-ese? you'd think just the sound of a diesel engine propelling a 90,000 ton container ship would be enough to get the message across, but apparently not.
