3、 is based upon a proposal by the Ship and Boat Builders National Federation. This standard has been prepared in order to meet a growing need for interchangeability of slides used in various track and slide fittings on board yachts. A wide adoption of these dimensions will also benefit both manufactu

4、rer and user in rationalizing a principal feature of design production. Two basic forms of track section have been covered, namely a flattened “C” section for internal fitting and a stub “T” for external fitting. Two sizes are given for both sections in order to meet the great majority of present ne

5、eds in yachting. A third large size has been added for the external fitting to meet a minor but significant need of the largest yachts. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.
