My experience is that the tile is not imbalanced (it doesn't always determine the winner).The game doesn't reduce too well to numerical analysis, but let's try. With a few more than 50 die actions, you're trying to average around 4 points per action. Scoring the max bonus for tile 15 takes 6 sell actions plus around 3 to 4 shipping actions. You get about 16 points for the shipping (in a 2 player game), plus probably around 10 for filling in a blue region, plus the 18. Around 44 points for around 10 actions (plus advancing yourself several times in turn order).
I think that this demonstrates that the tile is powerful but not uber-powerful.
