Floating docks for a century
 Dr. H.C. Wilkinson<$>
.5>A<$>T the end of the first decade of the 19th century, all the families on Ireland Island were removed from lands they had occupied for nigh on 200 years by the British military and the Bermuda Government.While the ground was possessed in the national interest in order to build the greatest Royal Navy dockyard in the Americas, several dozen families had to relocate to other parts of Bermuda and were never to return to their ancestral lands.
Their lands eventually fell in 1951 and 1995 to the Bermuda Government, which until late years neglected much of the built-heritage given over at those dates by the British military.
Beginning 1974 with the establishment of the Maritime Museum and in 1982 with the creation of the West End Development Corporation, the deterioration of the historic Dockyard was reversed and the area is now the most visited in Bermuda. What is missing now was missing then for the first 50 years of the Dockyard, namely, a dock; that is to say, a dry-dock.
A dockyard is so named because it is an industrial “yard” with workshops, artisans and a “dock” for repairing ships. In the absence of a dry-dock, ships had to be careened to have their hulls, or bottoms, repaired and cleaned.
In the early decades of the Bermuda Dockyard, careening capstans were located near the present ferry stop, with pits next to them to accept the yards of the ship. By careening, a ship was hauled over on one side, so that the opposite side was exposed for cleaning out.
A dry-dock is a basin in the land that could be flooded and a vessel floated in. A gate or caisson was placed behind the ship and the water pumped out, leaving the vessel in a “dry” dock, in which all the hull was exposed to the air for maintenance.
Such a repair basin was called a “graving dock” and for many years, a space was reserved in the Bermuda Dockyard for such a structure.
The local rock was an inappropriate material for a graving dock and so a London firm invented a iron “floating dry-dock” in the 1860s, at the period when iron ships, and later on, forts, were at the forefront of the Industrial Revoion.
Construction on thloating dock Bermuda began in 1866 and a model of the vessel was presented at the Paris Exhibition the following year. After launching in September 1868, Bermuda was towed across the Atlantic via the Azores 33 days.
After lifting 100 ships in 1945 alone, AFD 1 was sold to Regusci y Voulminot Ingenieros at Montevideo, Uruguay, one of the largest and most important harbours in South America. The dock left Bermuda in December 1946, after half a century of sterling duty. AFD 5 arrived in Bermuda in 1946, but had to be moored in Port Royal Bay, for berthing arrangements in the South Basin were not yet completed, including two 80-foot booms, “the largest welding job ever done in Bermuda”. The dock had twice the lifting capacity of AFD 1, which it replaced. On August 25, 1948, it was towed from Port Royal by the tugI>Justice and Eminent to the wharf in the South Basin, there to work for a m three years.
AFD 48 replaced AFD 28 at the North Basin wharf in late 1946 and was there employed for the next 26 years. It was sunk to the west of Dockyard in August 1972, ending its life, did the first dock, Bermuda, as a shipwreck.
