St at cud am 



The SUiiendam was a twin-screw liner laid clown in 

 the Harlan and Wolff, Ltd., shipyard at Belfast, North 

 Ireland, in 1921. A depression in the shipping business 

 delayed construction and the hull was not launched 

 until 1924, after which work ceased on the ship until 

 1927, when the hull was towed to Holland and the 

 vessel completed in Wilton's Yard, at Rotterdam, in 

 1929. The steamer owned by the Holland-America 

 Line and employed on the North Atlantic run, was 

 destroyed by the Germans at Rotterdam on May 

 10, 1940. 



The model is of a vessel with straight keel, a straight 

 upright stem slightly rounded at forefoot, upright 

 post and cruiser stern, with the propeller shafts housed, 

 a sharp entrance, long body and moderately long 

 run, and broken sheer. The long deckhouse bears 

 three stacks, two masts, and two sets of derrick posts. 

 The midsection is formed with a very slight rise in the 

 straight floor, a hard bilge on a small radius, and a 

 slight tumble-home high in the topside. 



The liner measured 698 feet extreme length, 91 feet 

 moulded beam, 34 feet depth, and 28,291 gross tons 

 register. She was gear-turbine driven, and her speed 

 was 20 knots. Scale of model is ]i inch to the foot.
