    • The boat or watercraft comprises a central board (1) and two side floats (2a, 2b) joined by bolts (35) to two transversal bars (3). The board and the floats have configurations and are made with materials similar to a conventional sail board. The board (1) is provided with a mast foundation hole (7a) and a center board well (4a) for solo navigation, with or without floats. Two other mast foundation holes (7b, 7c) in the board (1) are used in tandem with or without floats. Each float (2a, 2b) is individually usable by a child. The two floats may be assembled to form a catamaran by means of a floor provided between the two floats or by means of a central console supported by two longitudinal bars which may be fixed to the transversal bars (3). The console or the floor is provided with a mast foundation hole and with a center board well. Gutters provided in the board and in the floats receive the transversal bars and may fit on the roof rack bars of a vehicle. The assembly of the board, the floats and accessories such as bars form a kit which may be easily assembled and disassembled.
