The once calm weather outside the ship started to suddenly turn rough. The boat rock from side to side. Everything that wasn't nailed down was tossed about the various rooms. All the sailors of the ship rushed top side to help combat the storms. Loud thunder can be heard above, as water starts to flow into the lower decks. The thrashing of the ship worsens, and you all start to get pelted with various cargo and furniture. Large waves crashed over the ship flooding the ship with more water. The screams and shouting from the deck fade as one by one the sailors fall victim to the sea. Going above deck would prove to be suicidal unless you think you could swim the 27 miles to shore, and below deck you will be pelted with objects until you pass out, so it's up to you to choose the lesser of two evils. Speaking of evils, the succubus could just teleport away. If she felt like abandoning her daughter. After all the ship is moving and she wouldn't be able to find it again if she left.
