Definitions

  • the present invention relates to a mast for compensating the list of sailing boats, in order to improve navigating possibilities of the latter by affording them a maximum stability and great safety, even during the worst weather.
  • the present invention obviates these disadvantages by providing a mast with its stays and sails, articulated at its base and able to slope transversally. On this account, the ship can slope at about 30 instead of the boats hull, the latter thus retains its normal floating-line at a maxrmum.
  • the mast compensating for list is characterized in that its foot is mounted on an articulation integral with the hull of the boat, this mast being held at its top part by stays connected to a compensating device fixed inside the hull, this compensating device being controlled by a regulating device.
  • FIGURE 1 is an elevational sectional view of a sailing boat with canting mast.
  • FIGURE 2 is a plan view corresponding to FIG. 1.
  • FIGURE 3 is an enlarged elevational sectional View of the compensating device with portions broken away to show details.
  • FIGURE 4 is a perspective view, at an enlarged scale, of one part of the members of the compensating device.
  • FIGURE 5 is a perspective view of one of the devices for tensioning the shrouds.
  • FIGURE 6 is a plan view of a regulating device.
  • FIG. 1 shows, fragmentary sectional, the hull of a boat 1 where it can be seen, on the one hand, the mast 2 and its stays 3, and, on the other hand, the compensating device 4.
  • Dotted lines show the listing position of the mast 2 sloped at 30, the hull having remained horizontal in its normal water lines.
  • FIG. 1 shows that a mast step 6, secured on the bottom of the hull, comprises a spindle 5 around which the mast 2 can swivel.
  • a top mast bar 7 At the top of the mast, there is also a top mast bar 7 whose ends each terminate by a sleeve 7a securing the stays 3 and thus keeping them apart in a regular manner whatever the slope of the mast 2, in
  • This topmast bar which is incurved, is not fixed on the mast 2.
  • the stays 3 and their sheath 9 pass through a hole bored in the top part of each device for tensioning the shrouds 8, the stays 3 comprising, at a certain distance from said device-s 8, connecting members 3a enabling the two cables 10 to be fixed that are lodged in the sheaths 20.
  • the cables 10- are attached at their other end to a connecting bar 10a ending at a slide or anchor block 24, placed in a slide-bar or track member 23 forming with the slide 24 of the regulating device.
  • the hull of the boat is shown without the mast in order to display the location of the regulating device 11 and the compensating device 4 on a centreboard boat.
  • the centre-board well 12 is in the centre of the hull 1.
  • the compensating device 4 can be located at any point on the boat but it ,is necessary that the latters hull must be strengthened, for example, by two uprights extending from the fixed channel-plate, at a particularly strong point of the centre of the bottom of the hull 1.
  • FIG. 3 shows the compensating device fragmentary sectional.
  • This device is formed by a tube 13 closed at each end by a perforated cap 14 to allow the cables (under sheath) to pass, which form the stays 3.
  • These cables are joined or held in the centre, in a casing 15, known in itself, but after passing into the two parts 16 and 16a which are movable, inversed U-shaped, and have opposed bight portions placed perpendicularly to each other and each connected at their open end to a tension brace 17.
  • a spiral spring 18 is placed between the braces 17, this spring surrounding the parts 16 and 16a.
  • FIG. 4 shows in a partial perspective view, the tension member by the brace 17, of the compensator 4, placed between the U-shaped parts 16 and 16a.
  • the brace, as well as the parts 16 and 16a terminate by an angle plate forming a hook which holds the spring 18.
  • the brace is kept in position by studs or screws, extending from the arms of the parts 16.
  • FIG. 5 shows in a perspective view, a shroud tensioning device 8 shaped like a cap, fixing on the usual channel-plate 19 of the boat. It is from inside this device 8 that the protecting casing 9 of the cable 3 extends inside, the casing attachment 20 is fixed going to the regulator, this casing protecting the cable 10.
  • the regulator 11 can be seen which consists of a slidebar 23 fixed on the hull of the boat and drilled with a certain number of holes 23a fairly close together, as stated above.
  • the regulator 11 is fixed behind the centre-board well 12 within reach of the steersman who can thus easily operate it, this regulator enabling, with a steady wind, the stabilization in a suitable position of the exit of one of the strands of the compensator stays, according to the degree of list required.
  • the regulating device can be formed by a rack and a toothed member enabling the stabilizing of various operatory positions corresponding to a given slope of the mast.
  • a sail boat having a hull, a mast articulately mounted at its base in said hull, stays extending from opposite sides of an upper portion of said mast to opposite sides of said hull, and means connected between said stays and said hull for automatically compensating for list of said mast in relation to said hull, said means comprising a compensating device and a regulating device, said compensating device comprising a casing having ends of the respective stays threaded therein, a pair of overlapped U-shaped members having relative movement in said casing and having bight portions disposed in opposed relation, means secured to said stays and disposed between said bight portions, a spring circumposed about said U-shaped members and terminally engaged with said members for normally urging said members apart, and stirrups secured to each of said stays and respectively engaged with opposite ends of said spring.
  • said regulator device comprises cables connected to intermediate portions of said stays, an anchor block connected to said cables, a track member reciprocally receiving said anchor block, and means for adjustably positioning said anchor block in said track member.
