Abstract

A device for reducing sailboat heeling is disclosed. The boat or catamaran or trimaran or canoe with sails has a casing for a leeboard (31), or an outer opening or device for assembling a leeboard that is profiled like an airplane wing. To sail close-hauled, the leeboard (31) has to be deployed before the maneuver. If the waves are big, you have to steer to heel towards the other side of the boat (32), then you deploy the leeboard (31) and then maneuver the sailboat to heel to the other side (30). If you already sail close-hauled before changing the side of the heel, the leeboard is deployed from the casing.

This invention is for any boat or catamaran or trimaran or sailing boat.

All that is exclaimed in the description with the word boat is also for all the catamaran or the trimaran or the sailboat.

When the sailing boat sails at 45 degrees from the wind, said the boat sails to the meadows.

The boat (1) or catamaran (6) or trimaran or canoe, sail, when it sails to the meadows.

When the boat (1) sails in the meadow, the sail produces a lateral force and because of this, the boat needs to have a drift (2) or ballast.

If the boat shelters a lot (10), (15) the shape of the boat in the water is not symmetrical and it makes more turbe lance in the water and the boat went months fast.

The goal is to stay the month possible even with a lot of wind. The amount of sail is related to the weight of the ballast.

To reduce the heel of the boat may have a heavier weight, but it makes a boat heavier and more expensive, and also with low wind, the boat went slower, because it is heavier than necessary, for this intensity of wind.

It is possible to have a boat with more width to reduce the list, but it increases the friction and the boat is slower

With more intensity of wind, the boat lodges more.

Here the boat has a larger sail area, with the same wind intensity, he sleeps more.

It has a boat with mobile ballast, but the mobile ballast requires great physical effort even for the small boat, like four meters in length or hydraulic system for the larger boat.

When the houseboat (1) is in the lateral pressure drift (2) (4). When the boat is sailing with upwind or is stopped, it does not have a lateral pressure, (4) in the centreboard (2) and the body (3).

He has a boat with lateral fins (13), profiled in wing of plane, with each coast of the boat, to decrease the lodging.

The lateral fins (13) also need great human strength or the hydraulic system, etc. because it also has a vertical force (1 2) when the lateral fins (13) touch the water.

The sea is not always flat (5), it has waves (8) and also waves that comes from boats or currents, etc.

The new mechanisms are difficult to even impossible to assemble, in the boat already built.

When a catamaran (6) sails to the meadow and has gone faster, the catamaran (6) must have a float in the water and off the water (7). He sails with a little room. But if it has big waves (8) the catamaran (10) must be more, for the float (9) do not touch the waves, and this! A with the same intensity of wind.

The way the skipper should navigate is not always the same, and also the heeling angle, but adapts to the conditions of the sea, to the intensity of the wind, the way

or the skipper's desire to sail and also the angle with the wind, more or less in the meadow. etc.

The boat can not increase the sail area to go faster, because the width, weight of the ballast, distance between floats, etc. no longer admits lateral force or more angle of lodging.

The hull of the boat that is still in the water, may have some corrosion and

to raise seaweed, etc.

This makes it preferable that the mechanisms must be out of the water.

The state of technique is given for the following patents; FR2626240, US3870004. WO2007 / 116318.

Drawings four, five, six, seven, eight, nine and ten. illustrate the invention:

The method and device according to the invention can reduce the list of the boat, sailing.

With the method and device of this invention a boat already built can have lateral drift.

With the method and device of this invention a boat can have more sail area.

With the method and device a boat with more wind, it sleeps less.

The boat, have lateral drifts, profiled in airplane wing.

For the new boat it can have a box (1 1) or an external device (18) or a hole (20).

For the boat already built it is adapted a box (11) if it is possible or an external device (18) or an orifice (20) if it is possible.

The wing will have an effort (12). when he is in the water. The outer dis positive (18) is a piece which is glued with epoxy glue or the like, but it can be fixed with screws, etc., to the outer hull of the boat, at each side of the hull.

The outer device (18) may have reinforcement (19) with the keel or with the magpie or some other part of the boat.

The outer device (18) is a system for securing the lateral drift with an assembly system.

The inner device is an orifice (20) in the hull on each side of the boat, for assembling a lateral drift.

The wing-shaped lateral drift (22) has a shaft ( _, 24), which is introduced in

The outer device (18) or in the orifice (20), from it is fixed for an ankle, or as screws, or quick release, (21). (25), etc,

The shaft (24) may be shorter for the outer device (18) or longer for the orifice (20),

The boat can have several crates (1 1) and several external devices

(18) and several orifices (20) in the vertical and longitudinal directions.

The boat may have one or more crates (11) and one or more orifices (20) on one side of the ship and on the side of the hull, one or more crates (1 1) and one or more external devices (18). ), etc.

All combinations and quantities of cases (1 1), and devices

external (18) and orifices (20) are possible.

The goal is to lodge the possible months, but with more intensity of the wind the boat goes more lodging, therefore, the lateral wings must be bigger and with besides inclination.

The skipper according to the waves, the wind angles or that way of

to navigate in need of more or less cottage, and that makes it need a wing

different characteristics such as width, length and inclination.

The skipper can with the rope (14) change the angle of the box (1 1) and it gives of different inclination for lateral drift.

Also the skipper can leave more or month the wing (13) of the body (11).

With the external system (18) and the orifice (20) one can have several wings with different angles and different length and different width.

The wing (22) has screws (23) to have several angles related to the shaft (24).

It can be besides system, that gives the possibility to have several angles of the wing (22) in relation to the shaft (24).

When the skipper of the boat, sails off, wide, downwind and now wants to sail to the meadow, he must before changing course, choose the wing with the angle, length and width, he wants according to the lodging (6),

(10), (15), the intensity of the wind, big or flat waves, etc.

Before this side of the hull (26) of the boat touches the water, it must bring out the wing, the body (27) only since, the skipper makes the maneuver to go sailing in the meadows.

When the boat starts to sail in the meadows, the boat (15) and the wing

(13) touches the water and starts to generate a force to counterbalance the boat's heel.

The wing (1 3) at the moment that touches the water begins to make pressure

vertical (12).

If the boat to the outer system (18) or the port (20) with the wing (22) is the same procedure, as the previous description, only changes the wing type and assembly.

If the waves are large (28) and the water touches the body (29) or the outer system (18) or orifice (22) then the skipper follows the method of this invention;

The skipper leans the boat, for the coast (32) opposed to that he wants to sail to the meadows. The further side (30) of the shell is further out of the water, and that makes the body (31) or dε collects (18), or the orifice (22). do not touch the water.

The skipper or a member of the crew can pull out the lateral drift from the box (31) or introduce the wing (22) into the outer positive dis (18) or introduce the wing (22) into the orifice (20), without any physical effort.

Since the skipper makes the maneuver to navigate to the meadows of the off coast of the boat.

The skipper does not do the above maneuver if the multi-box (1 1) or the outer system (18) boat or the port (20), in the vertical or longitudinal direction. The skipper may choose a box (11) or outside system (18) or orifice

(20) above, which are not touching by the water ..

But the boat will sail more lodge.

If the skipper is already sailing in the meadow, the boat (15) is already lodged, with one side of the hull in

the water and the side of the hull touches little water (7), (9), (16) and the

wing box (17) or the outer positive dis (18) or port (20) does not touch the water.

When the skipper wants to change tack and before that, he pulls the wing out of the box (17) and only since the skipper changes tack.

If the boat has the positive external dis (I 8) or port (20), the procedure is the same as the previous description.

Since the maneuver the skipper or a member of the crew can pick up the keel at the body (1 1) or remove the wing (22) of the external system (18) or the orifice (20).

With the method of this invention, the skipper or a member of the crew does not exert any physical effort to pull the wing (13) out of the box (1 1) or to assemble the wing (22). , in the outer positive dis (I 8) or orifice (20), because all did with the lateral drift out of the water.

This melhode and inner (18) and outer (20) device are for boat or catamaran or trimaran, or canoe, sail, new or old, already built and new and also small or large size boat.
