By the way...
A ship must fit entirely within the spell's area to be affected by this spell, though creatures and objects on a ship's deck are affected normally. If an entire ship is affected and falls back down more than 50 feet, the pilot must succeed at a DC 20 sailing check when the ship lands or it gains the sinking condition.
