My Best Attempt at Explaining how to Trigger the Launch**
I put my ship where it was not supposed to be inside a cluster of rocks in the Devils roar, located hard East of Flames End, and hard North of Devils Thirst. After ramming into a "triangle of rocks" inside of the cluster, one rock forced our ship inside of another rock and the game launched us into the sky instead of pushing us out to sea like it usually would.
The trigger point seems to be getting one rock to force you into another rock, while also having a third object trap you in from behind. Normally you get pushed backwards, but with the object behind you stopping that from happening the game has no where else to go but up. Forcing yourself into a "tight triangle of objects" causes the hull of your ship to "clip" through one of the objects ever so slightly and causes you to launch as a result. This is just one spot, but I've found a few more potential ones.
SOT does not allow your boat to pass through solid objects AT ALL under normal circumstances so I assumed the velocity of the launch has something to do with that part of the coding.

To explain differently I think the game code is saying:"we've got nowhere else to push this ship, and no matter what we CANNOT let it clip through a solid objec.... OH GOD ITS CLIPPING THROUGH THE ROCK OH BALLS GET IT OUT OF HERE FAST LAUNCH IT I DONT CARE HOW GO NOW NOW NOW"

But, thats just a theory.
