Title: The passenger ferry Ailsa Princess off Stranraer.
Description: The passenger ferry 'Ailsa Princess' sailing from Stranraer to Northern Island. She is typical of the passenger RO-ROs - meaning 'roll on, roll off'. These have a large car deck instead of a cargo hold, and the vehicles drive on and off through a door in the bow or rear.
