NL7903765A - Crew support trapeze in sailing craft - permits movement from one side to other into go-about manoeuvre without uncoupling, or releasing rope - Google Patents

Abstract

The vessel is equipped with ringing, and its sail layout comprises a boom foresail (1) on an aerodynamic mast (2) with forward (3) and stern (4) stays. A trapeze device is incorporated, with the aid of which the crew in a to go about manoeuvre between mast and rear stay can go to the other side of the vessel without uncoupling the trapeze or having to let go the rope. The rope arrangement is such that only one rope behind the mast comes out of a block (5), so that the foresail can be used over both tacks. The automatic blocking unit installed is so arranged that navigating with the mast inclined windwards, it blocks midships when the mast moves from this position to leewards.

Description

V

Eenrieus A.M. Staarink in Delft.

The invention relates to a vessel equipped with a rig.

Known small sailing vessels attach their rigging to a mast, which is rigidly or rigidly connected to the vessel.

Another known type of sailing vessel, also called a sailing board, has an unsteady mast which is flexibly connected to the vessel in all directions via a ball joint or similar device.

The mast is held upright via a boom using body force. Boom manipulation establishes a balance between the forces on the sail, body weight and the forces on the board, allowing for heading and maneuvers.

10 The latter come about without steering. The size of the sail area is limited by the body weight of the sailor and varies depending on the wind force of 4-7 m2.

The present invention aims to provide a new sailing concept with features of both a sailing board and a sailing boat.

15 This object is achieved in that the vessel is equipped with a rig, characterized in that this rigging is rigidly arranged in a longitudinal direction between the fore-and-aft stays, but can be tilted transversely to both sides (towards windward) by more than 30 °, whereby the rigging amidships automations can be blocked and a sword device is provided, of which, when the surface is reduced, the thickness-length ratio of the horizontal section of the sword increases as well as the lateral point shifts forward and wherein a trapeze device is present is which does not need to be disconnected during the maneuvers and where a liner is present that can be held permanently during the maneuvers and where the deck plan is designed such that horizontal hanging in the trapeze in various ways and positions provides good 7903765 9 J 2 grip can be when sailing on all courses.

These measures allow the sail to be manipulated by the crew while sailing so that the sail point can be raised above or beyond the lateral point. This reduces the surface area and 3 also creates a vertical upward force component, in contrast to the vertical downward force component in sloping sailing boats. Only the transverse and vertical force component are in direct balance with the crew's body weight. As a result, 10 per person can be fed more sailing surface than is the case with a surfboard, which in principle increases the speed.

The invention will be further elucidated with reference to the drawing, in which figure I shows a side view, figure II a front view sailing over a bow, figure III the deck plan, figure IV a cross section of the deck plan, figure V the sword principle, figure VI the principle of the automatic blocking device and figure VII shows the mast construction.

Figure I shows the sail plan, consisting of a boom jib (1) on an aerodynamic mast (2) that is supported with front (3) and backstay (4). 20 The sailing point is as low as possible.

Hanging in the trapeze, the crew can move to the other board during a tacking maneuver between the mast and backstay without having to disconnect the trapeze and release the lap.

The sheet liner is designed in such a way that only one sheet behind the mast comes from a block (5), with which the jib can be operated over both bows.

The automatic blocking device is arranged such that sailing with the mast tilted towards windward (6) it blocks amidships when the mast would tilt from this position to lee. This blocking can be released to one side via lines (7) 30. At tipping * t, this blocking position is used to rebuild the vessel via the sword.

The deck plan (8) is designed in such a way that the vessel can always sail horizontally by means of the position of the feet on the deck at all courses and wind force.

Claims (3)

5 A steel wire rope is tensioned from the top of the mast to the end of a short boom (10). A tube of tarpaulin (11) is fitted over the entire length of the pipe and cable, in which there is an equally large air bag. After tensioning front and back, the hose can be inflated to the desired profile (12). Ecllusions: 10 1 · A vessel, equipped with a rig, characterized in that this rigging is rigid in a longitudinal direction but transverse can tilt over 30 degrees to the vessel on both sides, whereby the rig can be blocked amidships automations and in which a sword device is provided, of which, when the surface is reduced, both the thickness / length ratio of the horizontal section of the sword increases and the lateral point shifts forward, and wherein a trapeze device is present, which does not need to be disconnected during the maneuvers and wherein a sheet liner is present which can be held permanently during the maneuvers and the deck plan is designed in such a way that horizontally hanging in the trapeze in various ways and positions good grip can be obtained when sailing on all courses. 2. A vessel according to claim 1, characterized in that the mast has an aerodynamic shape, which can be rotated about its vertical axis. This aerodynamic shape can be obtained by placing a trunk over a round tube, tensioning front and back and then inflating the resulting internal space to the desired profile. , 3. A vessel according to any one of the preceding claims, characterized in that the side stays consist of a single continuous line, which is passed over two blocks fixed on the deck. The part of the stag in the middle between the blocks is thickened and caught in a rocking arm which, when tilted, releases the thickening to one side, but falls back into a lock. 7903765
