Im wondering .. if the water has a wave effect or not ? if so then keeping the boats water line in cue could be a problem..
Im wondering how easy it would be to give the plain a few more points, then deform them at the boats position, like displacing the water where the boat is, this would stop the water mesh from showing through the boat cos you just shoved that part of it down a bit. then just have the mesh return to normal as the boat moves, this could also give off a nice boat wake effect although I havent tried anything like this.
I hope it helps.
