I finally managed to make a working sea monster. The problem I was facing is that when an A.I. is placed in the water, it acts confused and won’t operate. I managed to solve this by placing the cockpit high above the A.I. with the part transform tool.

As you can see in this photo, the cockpit is moved high above the A.I. (I’m using my Liopleurodon for this example). This tricks the A.I. into thinking that it’s out of the water.

With the cockpit out of the water, the Liopleurodon starts heading toward the subject boat (sorry GranBuilder2942, but I had to scratch the paint on your fishing boat).

To my surprise, the Liopleurodon pursued the subject boat.

The Liopleurodon almost capsized the boat (mainly because I accidentally turned off the gyro by deactivating AG 8).

More tests will take place before I publish this. T to be tagged.
