Summer, 6303 Wynkoop Blvd, Bethesda, Md. 20034 Filed July 25; 1967, Ser. No. 655,830 Claims. (Cl. 114-98) ABSTRACT OF THE DISCLOSURE Rigging is connected with an intermediate portion of the boom of a sailboat for controlling the position thereof. A swingably mounted support post swingably supports block means which receives a first line interconnected with the boom for pulling on the boom for adjusting the position thereof. A further line is reeved over additional block means and interconnected with the support post for adjusting the position of the support post.

Background of the invention The present invention relates to sailboats, and more particularly to rigging for controlling the position of the boom and the draft of the mainsail. The rigging accordingly controls the swinging movement of the boom, and in prior art arrangements it has proved particularly dithcult to control the direction of pull of the boom in a light wind.

A so-called mid boom traveler has been developed wherein a block is slidably positioned on a support member which extends athwarthships, and suitable control lines are positioned by the movable block.

This type of mid boom traveler arrangement has proved unsatisfactory since the block thereof tends to stick in position and often does not provide the desired sliding movement. Additionally, the arrangement is such that the lines extending from the block to the boom apply a pulling'force on the boom substantially in a downward direction. This is undesirable since it tends to pull the boom down causing the sail to become inefficient in light winds.

Summary 0 the invention In the present invention, a support post is swingably supported at the lower end thereof by the sailboat, and the boom position control means includes block means swingably connected to the upper end of the support post. A line is reeved around this block means and additional block means swingably connected with an intermediate under portion of the boom. Further means is provided for controlling the position of the support post.

With the arrangement of the present invention, the sliding block arrangement as employed in the mid boom traveler type of structure is eliminated thereby eliminating the problems associated therewith.

Additionally and more importantly the arrangement of the present invention enables the pull applied to the boom to be in a direction more to the side of the boom and the sailboat rather than downwardly, and in fact the direction of pull is such that a line drawn along the direction of pull extends completely out of the sailboat.

The arrangement as described hereinabove is especially advantageous in light winds wherein it is desired to have a full sail. Since the force applied to the boom with the present invention is more to the side, the boom is allowed to rise and the arrangement does not have as much of a tendency to pull the boom down. The present invention arrangement also operates efiiciently in heavy winds.

An object of the present invention is to provide a new and novel sailboat rigging for controlling the draft of the mainsail which is equally effective in heavy winds as 3,396,689 Patented Aug. 13, 1968 prior art arrangements and which provides superior results in light winds.

Description of the preferred embodiment Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, a sailboat is indicated generally by reference numeral 20 in FIG. 1 and includes a cockpit 22. This sailboat is of relatively conventional construction and includes a rudder 24 mounted at the stern of the boat. A vertically extending mast 30 is provided, and a conventional boom 32 is swingably supported by the mast, a sail 34 being supported by the mast and boom in the usual manner.

A centerbored trunk 36 extends substantially along the centerline of the boat, and a thwart 38 extends between the opposite port and starboard sides of the boat.

Referring now to FIG. 8 of the drawings, a support post 40 may be of elongated tubular construction and includes a reduced ear 42 at the lower end thereof having a hole 44 formed therethrough. A similar reduced ear 46 is formed at the upper end of the support post and has a hole 48 formed therethrough.

A first pair of ears 50 extend laterally from the support post at the upper end thereof and have holes 52 formed therethrough. A similar pair of ears 54 extend from substantially the opposite side of the support post and have holes 56 formed therethrough.

As seen most clearly in FIGS. 1 and 9, a pair of ears 60 are secured to the upper surface of the centerbored trunk 36, and the lower end of the support post is pivotally interconnected with these ears through the intermediary of a pin 62 extending through aligned holes provided in ears 60 as well as the hole 44 provided in the lower end of the support post. The interconnection is such that the post 40 is free to swing from side to side of the sailboat and also has a certain degree of movement fore and aft thereof since the ears 60 are spaced apart sufficiently to allow such movement.

It will be noted that the elongated support post 40 is swingably mounted substantially along the centerline of the ship aft of the mast and in the illustrated embodiment just forward of the thwart 38, although its relationship to the thwart may be varied if desired.

Referring now particularly to FIG. 9, the boom position control means includes a first block means 60' swingably connected by a link 62' with a link 64 which in turn is swingably connected with the ear 46 formed at the upper end of the support post 4%). A block means 68 is also swingably interconnected with link 64.

A further block means 74 is connected through a link 76 with the undersurface of an intermediate portion of boom 32. A still further block means 78 is swingably connected through the intermediary of a link 80 with the undersurface of the boom.

Block means 68 is provided with a dead-end means 82 which receives one end 84 of boom control line, The boom control line includes a portion 88 which extends upwardly around block means 78. The portion 88 of the line then extends downwardly around block means 68. The portion 90 of the line then extends upwardly around block means 74, and the portion 92 of the line then extends downwardly around block means '60.

The subsequent portion 94 of the line extends downwardly and under an open cleat or guide means mounted on an inclined support member 102 which in turn is supported by the thwart 38. The line then extends through a conventional jamb cleat or holding means arrangement 104 and terminates inan end 168 which is adapted to be manually manipulated for applying the desired pull on the boom.

Components similar to those numbered 100, 102 and 104 are provided at the opposite side of the lower end of the support post and have been given the same reference numerals primed. These latter components are employed when the support post is in a different operative position as hereinafter described.

The support post position control means includes a pair of block means and 112 swingably supported from ears 50 at the upper end of the support post. A further block means 114 is swingably connected by means of a link 116 with a dead eye 118 secured to the thwart 38.

A dead eye 124 is also secured to the thwart, and a guide means or fairlead 126 is secured to the thwart.

An inclined support 130 is secured to the thwart, and jamb cleat or holding means 132 of conventional construction is mounted on this support.

A further pair of block means and 142 are swingably supported by the ears 54 disposed at the upp 2r end of the support post 40. Still another block means 144 is swingably connected by link 146 with a dead eye 148 secured to thwart 38.

A further dead eye 154 is secured to the thwart, and a guide means or fairlead 156 is also secured to the thwart.

A further inclined support means 160 is secured to the thwart, and a conventional jamb cleat or holding means 162 is mounted on this last-mentioned support.

A support post position control line has a first end portion 168 secured to the dead eye 124. The portion 170 of this line extends up over block means 110, and portion 172 of the line then extends downwardly around block means 114. The portion 174 of the line then extends upwardly around block means 112, and a further portion of the line 176 extends downwardly through the fairlead 126. The portion 178 of the line then extends through the jamb cleat or holding means 132, and a slack portion 180 extends across the thwart and through the fairlead 156 at the opposite side of the thwart.

The portion 182 of the line then extends upwardly over block means 142. The portion 184 of the line then extends downwardly around block means 144, and the subsequent portion 186 of the line extends upwardly over block means 140. The portion 188 of the line then extends downwardly and terminates in an end portion 190 secured to the dead eye 154.

The various components of the rigging of the present invention are illustrated in FIGS. 1, 4, 5 and 9 in the position that they will occupy under heavy wind conditions. It will be noted that under these conditions as seen in the drawings, the boom extends toward the port side of the sailboat, and that the support post 40 is also inclined toward the port side of the boat. In this position as seen in FIG. 9, the support post position control means to the port side of the sailboat is taut, and the line is held in place by the jamb cleat or holding means 132 so as to hold the support post in its operative position. The boom position control means line is manually grasped at portion 108 thereof and pulled to the extent desired to apply sufficient pull on the boom, whereupon this line is held in place by the jamb cleat or holding means 104.

Under these heavy wind conditions with the various rigging components in the position shown, a flat sail Will be obtained which is the desired result.

FIGURES 6 and 7 illustrate the position of the rigging components under light wind conditions. As seen in these figures, the boom is still inclined toward the port side of the boat, but the support post is inclined toward the starboard side of the boat.

Under light wind conditions, the support post position control means at the starboard side of the boat is taut, and the support. post position control means line is held in place by the jamb cleat or holding means 162. In this position, the boom position control means line is in an opposite relationship to that shown in FIG. 9 so that the line now extends under the guide member 100' and is held in place by the jamb cleat or holding means 104.

It is apparent that with the rigging arrangement as shown in the present invention, a person can readily control the rigging and effectively control the draft of the mainsail. This arrangement has proved to be very effective in light winds wherein it is desired to obtain a full sail, and it is also efiicient in operation under heavy wind conditions.
