Scows

The name "scow" derives from the Dutch , ultimately from the German for a punt pole and subsequently transferred to mean the boat. Old Saxon has a similar word which means to push from the shore, clearly related to punting. The basic scow was developed as a flat-bottomed barge ( a large punt) capable of navigating shallow rivers and sitting comfortably on the bottom when the tide was out. By 1848 scows were being rigged for sailing using

Sailing scows

Sailing scows have significant advantages over traditional deep-

sailing vessels that were common at the time the sailing scow was popular. Keelboats, while stable and capable in open water, were incapable of sailing into shallow bays and rivers, which meant that to ship cargo on a keelboat required a suitable harbour and docking facilities, or else the cargo had to be loaded and unloaded with smaller boats. Flat-bottomed scows, on the other hand, could navigate shallow waters, and could even be beached for loading and unloading. This made them useful for moving cargo from inland regions unreachable by keelboat to deeper waters where keelboats could reach. The cost of this shallow water advantage was the loss of the seaworthiness of flat-bottomed scow boats in open water and bad weather. The squared-off shape and simple lines of a scow make it a popular choice for simple home-built boats made from

In 1873, a sea captain named George Spencer, who had once lived and worked on the American Great Lakes and had gained a first-hand knowledge of the practical working capabilities of the sailing barges that plied their trade on the lakes, recognised the potential use of similar craft in the protected waters of the

Hauraki Gulf The Hauraki Gulf / Tīkapa Moana is a coastal feature of the North Island of New Zealand. It has an area of 4000 km2,Omaha, New Zealand, Omaha, not far from Mahurangi. An account of the launching of this vessel appeared in 1873 in the Auckland newspaper, ''The Daily Southern Cross'', which gave its readers a good idea of the distinctive construction and advantages over other vessels. The ''Lake Erie'' was 60 feet 6 inches in length, seventeen feet 3 inches in breadth and had a draught of three feet 4 inches. It was fitted with lee boards (a type of keel slotted onto the sides of the vessel), but these were highly impracticable in rough weather on the New Zealand coast. Later scows were constructed with the much safer slab-sided centre board, which crews raised and lowered as required. This one small craft spawned a fleet of sailing scows that became associated with the gum trade and the flax and kauri industries of northern New Zealand. Scows came in all manner of shape and sizes and all manner of sailing rigs, but the "true" sailing scow displayed no fine lines or fancy rigging. They were designed for hard work and heavy haulage and they did their job remarkably well. They took cattle north from the stockyards of Auckland and returned with a cargo of

or sand. With their flat bottoms they could be sailed or poled much further up the many tributaries and rivers where the bushmen and bullock teams had the freshly sawn kauri logs amassed, thereby saving a great deal of time and energy on the part of the bushmen. Flat-bottomed scows were also capable of grounding on a beach for loading and unloading. Over the side went duckboards, wheelbarrows, and banjo shovels. The crew then filled the vessel with sand, racing against the turn of the tide. When the tide did turn, they loaded the equipment back on board and put off to sea. Occasionally an inexperienced skipper overloaded the scow. Then, as the water rose against the outside of the hull (diminishing the amount of safe "free board"), the crew had to shovel rapidly to reduce the contents in the hold to a safe level. Logs when hauled were always carried above deck, secured by heavy chain, the space between decks being left empty to give added buoyancy. The logs were taken to Auckland and unloaded into floating "booms" to await breaking down in the sawmills of the Kauri Timber Company and other such mills that operated right on the edge of Auckland Harbour. The golden age of scows and
