ABSTRACT:
Folding trimaran which is symmetrical in relation to its median longitudinal axis and comprises a central hull, equipped with a mast, and also two lateral floats, which are connected to the central hull by at least one connecting arm. The trimaran can be moved between a first position in which the connecting arms are unfolded approximately horizontally on each side of the central hull, substantially perpendicularly to the longitudinal axis of the latter, and a second position in which the floats are folded along the central hull in such a manner as to reduce the space requirement. The trimaran has at least two connecting arms arranged symmetrically to define a maneuvering pair extending as far as the median horizontal axis. This pair is one on the other or separate at a place and are connected to the mast by one or two sliding carriages which can be moved in translation along the mast in order to enable the trimaran to be moved from the sailing position into the mooring position or vice versa by folding the two floats either at the same time or separately.
