<p>The two wheeled trailer transports a sailboard with a keel fin which can be held (20,21) in both planes. A carrying piece (19) supports the board above the ground at a height greater than the fin depth. The carrying piece has a base of reversed U-section, supported by the axle (2). The fixing of the keel fin is by a longitudinal hair type pin, fixed to the base and a 180 degs bend. The pin has a longitudinal slot to house the fin. Alternatively to the pin, two longitudinal rods may be used.</p> |
