Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 197 words
An outrigger stabilizer-mast step assembly for boats fitted with conventional saild comprising, in combination, journal means attachable to a boat hull with the longitudinal axis of said journal means disposed substantially within the longitudinal central plane of said boat hull at a point aft of the bow accommodating the associated mast in preselected position lengthwise of said boat hull, and a rigid frame mounted along its base edge within said journal means for free angular rotation in a plane substantially transverse said longitudinal central plane, said frame being provided with an upwardly oriented mast step and, attached to an edge of said frame disposed radially outward from said base edge, outrigger supports extending outboard substantially normal laterally with respect to said frame from both gunwales of said boat hull preselected distances abeam, said outrigger supports being each provided with stabilizer means secured at the outboard ends of said supports in planes generally coparallel with the longitudinal plane of said rigid frame, both said stabilizer means being disposed at substantially equal immersion levels within water floating said boat hull when said frame is disposed in equilibrium position in alignment with said longitudinal central plane of said boat hull.
Claim 2
Dependent Claim 197 words
An outrigger stabilizer-mast step assembly for boats fitted with conventional saild comprising, in combination, journal means attachable to a boat hull with the longitudinal axis of said journal means disposed substantially within the longitudinal central plane of said boat hull at a point aft of the bow accommodating the associated mast in preselected position lengthwise of said boat hull, and a rigid frame mounted along its base edge within said journal means for free angular rotation in a plane substantially transverse said longitudinal central plane, said frame being provided with an upwardly oriented mast step and, attached to an edge of said frame disposed radially outward from said base edge, outrigger supports extending outboard substantially normal laterally with respect to said frame from both gunwales of said boat hull preselected distances abeam, said outrigger supports being each provided with stabilizer means secured at the outboard ends of said supports in planes generally coparallel with the longitudinal plane of said rigid frame, both said stabilizer means being disposed at substantially equal immersion levels within water floating said boat hull when said frame is disposed in equilibrium position in alignment with said longitudinal central plane of said boat hull.
Claim 3
Dependent Claim 16 words
An outrigger stabilizer-mast step assembly according to claim 1 wherein said stabilizer means are buoyant floats.
Claim 4
Dependent Claim 29 words
An outrigger stabilizer-mast step assembly according to claim 1 wherein said outrigger supports are fixedly attached to said edge of said frame disposed radially outward from said base edge.
Claim 5
Dependent Claim 127 words
An outrigger stabilizer-mast step assembly according to claim 1 having said outrigger supports attached at their inboard ends to tubular means co-axially mounted in free rotational relationship with respect to said edge of said frame dispOsed radially outward from said base edge, and a closed loop running shroud line extending from an elevated point on said mast through fairleads carried by each of said stabilizer means and thence to ring means in substantial alignment with said longitudinal central plane of said boat hull when said boat hull and said stabilizer means are substantially in horizontal balance, and disconnectible means pinning said ring means to the angularly rotatable portion of said rigid frame, said disconnectible means being operable manually or automatically as a function of boat heeling angle.
