Between 1946 and 1950 the Ailsa Shipbuilding Co.Ltd, Troon, built five steam colliers for the Hudson Steamship Co. Ltd., they replaced tonnage lost by the company during WWII
HUDSON STRAIGHT and HUDSON CAPE completed in 1946 had four hatches, intended for the NE/London coal trade they of course needed no unloading gear
HUSON RIVER and HUDSON FIRTH completed in 1949 were slightly larger vessels, boasting an additional hatch in their well decks
The ever increasing number of colliers available for the coal trade was probably what prompted Hudsons in the early 1950's to have HUDSON FIRTH fitted with derricks, and winches, and her boiler converted for oil firing which increased the ships operational range. She consequently spent much of her time in the West Indies sugar trade
HUDSON SOUND completed in 1950 was equipped with derricks, winches and an oil fired boiler from new, having just four hatches she was smaller than the two vessels which preceded her. Much of her trading took her to Baltic and Mediterranean ports
The five-hatched HUDSON RIVER was sold in 1973 to Sea Channel SA, Panama, her new owners didn't use much imagination when they renamed her IVER.Trading for a further three years she ended her days in the hands of ship breakers at Aviles
The four-hatched HUDSON SOUND was sold for £48,000 in 1967 to the Darien Shipping Co. Inc., Panama, and renamed ROSELLA
In 1970 her registered owner became the Gulf Nav Corp., Panama. who renamed her CATHAY
Following her sale in 1971 to the Old Dominion Maritime Corp., Panama, she was renamed VEDALIN
Spanish ship breakers disposed of the ship at Burriana in 1973
If my record cards are to be believed then I photographed both vessels on May Ist 1965
