It looks like the API doesn't give access to the whole shape of a ship - only its centroid position and the direction of the sharpest vertex. Do the other vertices not matter? In any case, we should probably be able to compute which edge we would be splitting and stuff like that.

They matter in that they might ram you :-). You also have another ship's moment of inertia, which tells you something about it. But no, you're not provided other ships' geometries. I could change this, but likely not during the contest.
