What happens when a ship pushes a figure sideways into another ship? Does this prevent the ships from closing rail to rail? What about a figure caught between a sandbar and ship, or rock and ship? Can this prevent the ship from being dashed upon the rocks or does the figure just get pushed out the nearest end?
There doesn't seem to be anything about it other than a section under Sailing the Ship:
Colliding with Figures: Figures that a ship collides with are simply pushed ahead of the ship (even if soaring, since otherwise situations could be created where multiple figures are in the same space). No damage occurs to either the figure or the ship. If a figure is pushed off the edge of the map, that figure is considered to have fled the encounter.
That is the complete, and exact way it's printed in my copy (North American Ed)
