During the Transatlantic maiden voyage of RMS Persia, the largest ocean liner in the world at the time, the vessel collided with an iceberg. The incident resulted in the rivets in a section of her hull plating near to the bow being spung. However, the ship remained watertight and she was able to complete her voyage unassisted. Her survival of that serious incident was put down to her clipper bow and the stoutness of her construction. Happily, there were no human casualties, however, as is well known, 56 years later the outcome of a similar incident was a tragedy that shocked the world.
