What has been created is the fastest sail boat that can act as a tugboat or industrially used to pull a water turbine for the production of electricity or compressed air, as compared to the capabilities of the prior arts of equal size and form. This is attained by the use of water as counterweight contained and locked-in inside an impervious pipe which may be of the same length as the boat, which is attached at the side or preferably under the hulls of a catamaran type boat, or which is attached to each lower side of a mono-hull boat;－by erecting as many large square sails as possible along the longitudinal axis of the boat in an arrangement to form an aggregate dwarf sail to bring down the centroid of the aggregate wind force close to the level of the boat to minimize the overturning moment of the wind upon the boat, thereby maximizing wind contact within the stability limits of the boat;－by making the hulls vertically thin to minimize resistance thru the water;－by adding a short float booster pipe on top of the main floater pipes, which extends beyond the front and rear ends of the hull to provide extra buoyancy on the sinking side when the boat is tilted too far.

A new structural design for a sail boat, comprising: guy ropes, and a plurality of masts; said boat having a plurality of hulls, each hull being comprised of a plurality of long impervious pipes which are stacked in a single vertical plane forming a hull structure, the upper pipe being a main floater pipe and the lower pipe serving as a counterweight; said counter-weight being in the form of a water-tank that is calibrated to float by 5% to 10%, and which may be of the same size and length as the main floater pipe; a short float pipe which is larger in diameter than the main floater pipe, and which is horizontally disposed on the top end of each main floater pipe, and extended forward and rearward beyond the main floater pipe above the water line, to serve as a float booster; a plurality of structural tie points for the guy ropes, one each beyond the front and the rear of the boat, which tie points consist of a structural pipe member that is horizontally disposed on top of said float booster and which is extended beyond the outer ends of said float booster to form a triangular structure beyond the ends of the hull structure; struts to push out the guy ropes away from the masts and clear off the sails, said struts being in the form of a horizontal cross-arm structural pipe that is disposed along each guy rope and is at least five feet below the top end of each mast, the length of said struts being coextensive with the top width of the sail; a plurality of independently erected large square sails, each said square sail being made out of a light strong fabric with a rigid frame at the top and at the bottom, each sail being erected along the longitudinal axis of the boat such that at least one sail is erected beyond the front end of the hull structure and another sail is erected behind the rear end of the hull structure providing a horizontal expansion of the sails along the length of the boat; a grid of strings or straps provided at the back face of each sail to reinforce the strength of said fabric against the excessive pressure of the high speed winds; a means to further deflect the wind to develop more wind pressure and a larger forward dynamic force upon the sails, said means being in the form of a plurality of vertical flap wing deflectors made of framed fabrics, said fabrics attached to each side of the square sails by a zipper; said deflectors being framed at the top, bottom, and rear sides by a rigid pipe which serves as a stiffener to the vertical sides of the square sail, the front ends of the deflector frames being securely connected to the ends of the square sail frames by means of a hinge connector to allow said deflector to flip open or closed; a means to hold said deflector at a fixed angle with respect to the main sail, said holding means being a rope one end of which is tied to the rear end of the upper and lower frames of said deflector and the other end of which is tied to a point near the mast; a flat “U-Bar,”vertically disposed, to assemble the water-tank pipe, the main floater pipe, and the float booster pipe together in a single vertical plane to act in a unitary fashion so as to serve as the hull for said boat; said “U-Bar”being bolted upward thru and at right-angles with respect to a horizontally disposed structural beam to hold said hull in a single vertical plane; said structural beam, which may be made of a rectangular box pipe, being disposed perpendicular to the hulls with at least two beams interconnecting the hulls and holding the hulls parallel to each other; a mast to hold upright each sail, each mast being erected on the mid-section of each of the said structural beams, said masts being made of pipes which taper to the top; a plurality of guy ropes tied to the top of each mast, and thru the outer tip of each cross-arm, and tied down to the outer tip of said structural beam, to hold the masts rigidly vertical; a longitudinal guy rope which holds together all the masts so as to stand rigidly vertical, said longitudinal guy rope being tied to the said structural tie point at the front of the boat, then proceeding up to a forward cross-arm and then to the top of a first mast, to the top of a second mast, to the top of a third mast, to the top of a fourth mast, to a rearward cross-arm, and ending tied down to the said structural tie point at the rear end of the boat; a control rope attached to several points along the frames of the sail; an upper ring bearing connector, disposed at the upper section of each said mast, thru which the upper frame of each sail is attached to the mast, which bearing carries the whole weight of said sail thru a plurality of suspension ropes, and which bearing is a means to allow the sail to revolve around said mast; a lower ring bearing connector, disposed at the lower section of said mast, thru which the lower horizontal frame of said sail is attached to the lower section of the mast thru a plurality of control ropes spacedly tied to said horizontal lower frame of the sail, which bearing being a simple loose ring that can freely move up and down the mast when the sail is being folded up or unfolded down, and which also serves as a means to allow the sail to revolve around said mast; rudders disposed at both ends of the boat to steer the boat in either direction, since the boat may use its rear end as its front end thereby permitting it to reverse direction without turning around; a linking rope one end of which is tied to the outer tip of each said structural tie point at the ends of the boat, and the other end which is tied down to the bottom end of each hull structure; a floor fastened to the lower face of said structural beams; a water-turbine attached to the bottom end of each mast, which turbine is capable of being moved in and out of the water, which turbine is driven by running water under the boat, and a central control winch installed at both the right and left end of each said structural beam, said winch being made of a double drum, said drums being interlocked and driven by a continuous drive shaft starting at the rear end of the boat and extending all the way to the front end of the boat, such that one drum releases the control rope at the left side of the sail at the same time the other drum tightens the control rope at the right side of the sail when said drive shaft is turned clockwise, in order that a single operator can control all the sails simultaneously.
