Water behind ships much bluer than rest of ocean

How can I take a long-time exposure of water without a grey filter?

Assuming you're doing the obvious - setting ISO to the minimum and using the smallest aperture you can - then there's nothing else you can do without an ND filter. They're not that expensive :-)
