Abstract
Abstract Sailing rig for a sailing vessel in which a pair of sails are transversely spaced from each other and on opposite sides of a main mast mounted on the centerline of the hull. These sails are both supported by the main mast by means whereby the sails may pivot relative to each other independently about their respective pivot axes, which pivot axes are fixed relative to each other and are rotatable as a unit about the main mast.

Total Claims: 12
Claim 1
Independent Claim
293 words
In a sailing vessel adapted for efficient sail use including hull means, a main mast having upper and lower portions, and at least two sails, the improvement permitting interchangeable sail positions variable by the user under different sailing conditions, comprising: substantially identical starboard and port sails, each having a luff portion, starboard and port sail masts, said starboard sail mast being for said starboard sail and said port sail mast being for said port sail, and means for mounting said sail masts for rotational movement about said main mast in a circular path, said mounting means including a pair of cross piece members rotatably mounted at the upper and lower portions of said main mast, each comprising arms projecting from said main mast, one arm of each of said cross pieces being secured to each of said sail masts toward the ends thereof, said arms on each of said cross pieces being substantially equal in length and arranged to rotate in fixed relation relative to one another about the main mast, said sails being capable of being secured to said respective sail masts along the luff portions thereof, means for pivoting said sail mast mounting means to simultaneously rotate said sail masts about said main mast in a circular path for variably positioning the luff of one of said sails forward of the luff of the other of said sails, said pivoting means making each of said sails adjustible to serve as a foresail with the other of said sails serving as a mainsail depending upon the reach, and means associated with each of said sails for positioning said sails to traIl aft in generally mutually parallel relation, to converge, and to independently swing laterally outboard of said hull means in opposite directions.

Dependent Claim
293 words
In a sailing vessel adapted for efficient sail use including hull means, a main mast having upper and lower portions, and at least two sails, the improvement permitting interchangeable sail positions variable by the user under different sailing conditions, comprising: substantially identical starboard and port sails, each having a luff portion, starboard and port sail masts, said starboard sail mast being for said starboard sail and said port sail mast being for said port sail, and means for mounting said sail masts for rotational movement about said main mast in a circular path, said mounting means including a pair of cross piece members rotatably mounted at the upper and lower portions of said main mast, each comprising arms projecting from said main mast, one arm of each of said cross pieces being secured to each of said sail masts toward the ends thereof, said arms on each of said cross pieces being substantially equal in length and arranged to rotate in fixed relation relative to one another about the main mast, said sails being capable of being secured to said respective sail masts along the luff portions thereof, means for pivoting said sail mast mounting means to simultaneously rotate said sail masts about said main mast in a circular path for variably positioning the luff of one of said sails forward of the luff of the other of said sails, said pivoting means making each of said sails adjustible to serve as a foresail with the other of said sails serving as a mainsail depending upon the reach, and means associated with each of said sails for positioning said sails to traIl aft in generally mutually parallel relation, to converge, and to independently swing laterally outboard of said hull means in opposite directions.
Claim 3
Dependent Claim
283 words
A sailing rig for use on a sailing vessel having hull means, comprising: a starboard sail having a luff, a port sail also having a luff, a main mast mounted on said hull means, an upper cross piece having a starboard and a port arm relatively rotatably fixed with respect to each other, said upper cross piece arms being rotatably mounted on and extending radially outwardly from said main mast, a lower cross piece also having a starboard and a port arm relatively rotatably fixed with respect to each other, said lower cross piece arms being rotatably mounted on and extending radially outwardly from said main mast, a starboard sail mast, on which said starboard sail is supported along its luff, mounted between said upper cross piece and said lower cross piece, and a port sail mast, on which said port sail is supported along its luff, also mounted between said upper cross piece and said lower cross piece, said upper cross piece, said lower cross piece and said starboard and port sail masts forming a sail mounting means means for pivoting said sail mounting means to simultaneously rotate said sail masts about said main mast in a circular path for variably positioning the luff of one of said sails forward of the luff of the other of said sails, said pivoting means making each of said sails adjustible to serve as a foresail with the other of said sails serving as a mainsail depending upon the reach, and means associated with each of said sails for positioning said sails to trail aft in generally mutually parallel relation, to converge, or to independently swing laterally outboard of said hull means in opposite directions.
Claim 4
Dependent Claim
283 words
A sailing rig for use on a sailing vessel having hull means, comprising: a starboard sail having a luff, a port sail also having a luff, a main mast mounted on said hull means, an upper cross piece having a starboard and a port arm relatively rotatably fixed with respect to each other, said upper cross piece arms being rotatably mounted on and extending radially outwardly from said main mast, a lower cross piece also having a starboard and a port arm relatively rotatably fixed with respect to each other, said lower cross piece arms being rotatably mounted on and extending radially outwardly from said main mast, a starboard sail mast, on which said starboard sail is supported along its luff, mounted between said upper cross piece and said lower cross piece, and a port sail mast, on which said port sail is supported along its luff, also mounted between said upper cross piece and said lower cross piece, said upper cross piece, said lower cross piece and said starboard and port sail masts forming a sail mounting means means for pivoting said sail mounting means to simultaneously rotate said sail masts about said main mast in a circular path for variably positioning the luff of one of said sails forward of the luff of the other of said sails, said pivoting means making each of said sails adjustible to serve as a foresail with the other of said sails serving as a mainsail depending upon the reach, and means associated with each of said sails for positioning said sails to trail aft in generally mutually parallel relation, to converge, or to independently swing laterally outboard of said hull means in opposite directions.
Claim 5
Dependent Claim
104 words
The sailing rig as claimed in claim 2, wherein said port and said starboard sail masts are mounted in fixed relation to each other and pivot about said main mast in the circular path while maintaining this fixed relation, and wherein said pivoting means include: a line of fixed length extending between the outer ends of said lower cross piece starboard and port arms, beneath said starboard and port sail masts, a pulley fixedly mounted on said hull means through which said line is guided, and means for paying said line through said pulley for pivoting said sail mounting means about the main mast.
Claim 6
Dependent Claim
60 words
The sailing rig as claimed in claim 2, wherein said sail mounting means also comprises: a brace connecting said upper cross piece starboard and port arms, and said starboard sail mast being mounted between said lower cross piece starboard arm and said brace, and said port sail mast being mounted between said lower cross piece port arm and said brace.
Claim 7
Dependent Claim
