great animation:bow:

I would however make the water a little darker it's to bright in contrast to the setting.
And if i look at your animation it looks like a windy day try to make the sail bulge in and out a little(wave deformer perhaps?) to add realism.

edit;
Maybe you could prevent the water from entering your boat by duplicating the boat scale it a little bit up make this your collisionobject, and turn off the visibillity
