Empty The Water Out Of My Boat?

[andywhiting2010]

Can anyone help me with problem please.
I'm trying to animate a gut sitting in a rowing boat in the middle of the ocean.
I get the boat to float on the water but the plane of the water cuts the geometry of the boat making it appear that the boat is full of water. Any ideas how I can make sure the water doesn't come inside?
Thanks
