<p>The motor board refers to the area of traffic by vessels. It is intended for travelling on water surfaces and consists of a board (1), an indicator (18) as known from the present state- of- the- art in technology, an engine (2) with a fuel tank (25) and a ship's screw (5) which is by means of a plug (20) and rings (25, 26) fixed to the board (1). The motor board can be temporarily rearranged into a sailing board by removing the plug (20) with the permanently built-in engine (2) and replacing it by the plug (20) that has instead of the engine (2) a sleeve for the foot of the mast.</p> |
