The Swiff Dory Recreational Rowing Craft

Introduction
The "Swiff Dory" is a swift rowing dory which is a delight to row. It is probably the fastest one man rowing boat available for recreational use. It is being offered with two rowing positions and a rudder so that it can be rowed in a variety of ways and with considerable ease. Apart from the elegant and efficient design, the ergonomics of rowing are very refined. In fact the GACO rowlock was developed as part of this refinement.

Design History
The Swiff Dory hull shape has evolved over a period of a hundred years or more. It is based on the Adirondack Guide boat and drawn up by the American Halsey Herreshoff in 1947. It was refined by the famous small boat designer John Gardner to increase its seaworthiness . The Swiff dory has been further refined and adapted for fibreglass construction. Dories are a kind of rowing boat with a flat bottom originally designed to fit inside each other for use on fishing schooners. The flat bottom is a design feature particularly suited to speed as it permits of a narrow hull with adequate stability. Herreshoff described the hull as "falling between the fragile racing scull and the heavy ill shaped rowing boat of several hundred pounds". The hull is 5.5 m (17ft.) long 1.2 metres wide and weighs 51kg. Rowed with vigor it will travel at 6 knots and can easily do 5.



Applications
There are many examples of the Swiff Dory in use as commuter boats on Dangar Island where their ease of rowing, room and sea-worthiness is fully appreciated. They have been employed partly as a green solution to dangerous, noisy and smelly "tinnies". Recreational applications, however, are also an attraction and they are used for picnics, exploration and exercise. The Swiff Dory is capable of carrying up to six people but is designed to carry between one and four.
