Steam Schooner WAPAMA
Known as s "single end steamer," Wapama has her engine and machinery housed aft. Some vessels had their engines housed midships and were known as "double ended."
A high superstructure on the stern and a high forecastle on the bow are distinctive features of Wapama. The masts and spars support booms for loading and off-loading cargo and are equipped with two sets of friction winches. These powerful winches were designed to allow Wapama to load and off-load by herself without the use of shore cranes. The ability to do this was an asset in the lumber trade, where ports were primitive and lacked shore facilities for cargo loading.
Wapama had one main hatch for loading. In addition to 60 passengers, the ship could carry 1,100,00 board feet of lumber, which included a deckload 15 feet deep.
The vessel was powered by a triple expansion engine, Indicated Horsepower (ihp) 800, built by the Main Iron Works of San Francisco. The engine was powered by water tube boilers, and the boilers burned diesel oil.
The interior of the Wapama is divided into various sections, the largest being the hold where the cargo was stowed. Other spaces were reserved for machinery, the engine room, crew quarters, the galley, passenger areas, and the pilothouse. Because the vessel has a radical sheer, all the interior woodwork was fitted to the ship. This means that no doorway, or other opening, is square.
Did You Know?
Loading ports are small, watertight doors in a ship's hull that lead directly into the hold. Lumber could be more easily loaded into the hold through these ports rather than through the smaller hatches on the deck. These ports had to be caulked shut before the ship put to sea. More...
