IT'S not only on the Great British Bake Off that you lose marks for a 'soggy bottom'.

When it comes to shipbuilding, a leaky hull is also a no-no.

These guys, photographed at John Brown's shipyard in Clydebank in 1906, were about to 'helmet up' to carry out a pre-sea-trials underwater inspection of the hull plates on the Cunard liner, RMS Carmania.

The very thought of diving into the dark and dirty water, depending on the men topside to maintain your air supply, gives us the heebie-jeebies.

When launched, the Carmania was the largest ship in the Cunard fleet. She sailed the New York-Liverpool route from 1905 to 1910. In 1906, she carried the novelist H.G. Wells on his first trip to America.

In October 1913, she responded to a distress call from the Volturno to pick up survivors in a storm, resulting in many awards for gallantry being presented to Captain James Clayton Barr and his crew.
