I was in the Society of Leopold making the run for the Zodiac. I didn't turn the corner fast enough on the dock and ran straight into the water. I started looking around rabidly for a ladder, couldn't see one, so I tried jumping into the Zodiac from the water (which didn't work either). Then I ran out of time, the screen went black, and I was back in front of the Venture tower. I got full credit for the quest, just like I'd escaped on the Zodiac. I guess you win if you just get off the dock, not necessarily
into the Zodiac.
