A collapsible boat includes a center pontoon and two side pontoons which can be moved toward or away from one another and toward or away from the center pontoon. The center pontoon is fixed in position and is accommodated by a cradle fixed in position on a trailer. The trailer includes two movable cradles which accommodate the movable side pontoons of the collapsible boat so that the trailer can be widened or narrowed when the boat is widened or narrowed.
