A multihull vessel has a center section; a pair of floats displaceable from normal positions laterally extended on either side of the center section upwardly to positions above the center section and inwardly toward the center axis of the vessel as well as downwardly toward any hull or sides of the center section and inwardly to positions below any superstructure of the center section; arms consisting of pivotally mounted and jointed members connecting the floats to the center section and capable of positioning and maintaining the floats at positions between fully raised and fully lowered; one or more masts displaceable from a fully vertical position to a fully prone position; elements of standing rigging of effectively adjustable length between mast and center section or floats and apparatus for adjusting singly or in coordination, even while underway, moored or capsized, with inboard, in-place and centrally located control device, any of the floats or masts to any allowable orientation with respect to the center section. Operations possible with such a vessel include: unaided righting of the capsized vessel, reducing the beam to that of the center section for trailering or accommodating a narrower berth or passage, lowering the mast for stowage or for accommodating a berth or passage of restricted height, and changing the relative positions of aforementioned elements of structure or rigging for improvements in performance, safety or comfort in various sailing attitudes.

A multihull vessel comprising: a center section, standing rigging mounted to the center section and extending thereabove, a pair of floats disposed on opposite sides of the center section and spaced therefrom, pivot connection means pivotally connecting each float to the center section for movement between a first position laterally extended from the center section to render the vessel stable in an upright condition, and a second position located beneath the center section when the vessel is fully capsized, to render the capsized vessel unstable by locating the center of buoyancy of the capsized vessel below the center of gravity to promote righting of the capsized vessel; the standing rigging being displaceable from interference with movement of the floats to their second position so That the floats can be located closely adjacent the vertical centerline of the capsized vessel to maximize the instability of the fully capsized vessel.
