Boat in the water

 I have been looking at the movement of the boat in the water as to wheather to use the locator or to key the boat in the stormy sea. 

 

Boat Keyed which i think will be the best option for our film

 

Locator on boat, the angle is not the best here but after messy with settings for a while trying to get it to work better, i think there is just to much going on that it is unsure what to do there for the keying the boat would probably be best.
