FOIL SEAT FOR A SEMI-RIGID BOAT

Abstract

Semi-rigid boat sailing on a foil (1) comprising a foil well for raising the foils on the boat in the high position, characterized in that the foils are foils with shortened arms positioned laterally at the level of the driver's seat (12), the foil well fits into the driver's seat which is a trunk with two side doors (41, 42) which open onto the foil position stop adjustments (43, 44), inside the seat trunk there is a shock absorber (44) to cushion navigation shocks.

Claims

1. Semi-rigid boat navigating on a foil (1) comprising a foil well for raising the foils on the boat in the high position, characterized in that the foils are foils with shortened arms positioned laterally at the level of the driver's seat (12), the foil well fits into the driver's seat which is a box with two side doors (41, 42) which open onto the foil position stop adjustments (43, 44), inside the seat box is arranged a shock absorber (45) to dampen the shocks of navigation

2. Semi-rigid boat sailing on foil (1) according to claim 1 characterized in that actuating triggers (60) for translation of the foils (1) in the foil well are positioned under the seat on each side of the seat with an opening in the side doors (41, 42) about ten centimeters below the level of the pilot's buttocks which allows the pilot to actuate the actuating triggers while remaining seated and positioning his hands below the level of his buttocks on either side of the sides of the seat

Description

[0009] The invention will be better understood on reading the appended figures in which

[0010] FIG. 1 represents a section of a semi-rigid boat according to the prior art

[0011] FIG. 2 represents a side view of a semi-rigid boat equipped with the present invention

[0012] FIG. 3 represents a top view of a semi-rigid boat equipped with the present invention

[0013] FIG. 4 shows a section of the seat box of the present invention

[0014] FIG. 5 shows a top view of the foil deployment trigger principle.

[0015] FIG. 1 represents a section of a semi-rigid boat according to the prior art with a the cockpit (11) that includes the piloting controls and in particular the steering wheel, the foils (1) which rise and which descend at the interior of the cockpit depending on the navigation conditions. Shown to the right of the cockpit (11) is the seat (12). It is well understood that foils that descend a height (Hv) underwater need to ascend a height (Hv) when the foils rise. And this height (Hv) translation is made possible in the cockpit because the steering wheel is located substantially at shoulder height of pilot. This is impossible with a seat because the foils could not rise sufficiently in the storage position and would be blocked.

[0016] FIG. 2 shows a side view of a semi-rigid boat equipped with the present invention in which the cockpit (11) has been moved forward of the boat, the seat (12) has also been moved forward on the boat in front of the foils (1) according to the old position of the prior art. In this position, the foils come into the boat and are stored under the seat (12).

[0017] FIG. 3 represents a sectional view of the new layout of the boat arrangement with foils at seat position, and with a maximum height under water (Hs) which is reduced compared to the height (Hv) previous. This is possible without modifying the quality of navigation because the advance of the center of gravity presses the boat on the water in a high-speed navigation position and the foils need less to be long to get lift in the water.

[0018] FIG. 4 shows a sectional view of the seat (12) according to the invention which has the shape of a box with two side doors (41, 42) to access the high and or low wedging adjustment of each foil (1). The settings are a combination of hooks (43) on the box and stop (44) on the foil which allow the foil to be wedged in the high or low position. The actuation of the foils can be done by hand by straps or can be motorized. The inside of the seat has a shock absorber (45) which absorbs shocks and gives the pilot a comfortable seat.

[0019] FIG. 5 shows a top view of the principle of the actuating trigger (60) for translation of the foil which, when actuated, frees a space (61) to block or not this space for the passage of the foil (1) by the play of the position of the stops (44) with the vertical translation of the foil (1) in this passage (61). The pilot has two triggers (60) each positioned on each of the side openings of the seat box. He can thus easily while remaining seated, control the translation of the foils by simply lowering his hand just below his buttocks.

[0020] The present invention therefore relates to a semi-rigid boat navigating on a foil (1) comprising a foil well for raising the foils on the boat in the high position, characterized in that the foils are foils with shortened arms positioned laterally at the level of the driver's seat (12), the foil well fits into the driver's seat which is a trunk with two side doors (41, 42) which open onto the foil position stop settings (43, 44), inside the seat box is provided with a shock absorber (44) to absorb the shocks of navigation

[0021] The present invention therefore relates to a semi-rigid boat sailing on a foil (1) characterized in that the actuating triggers (60) for translation of the foils (1) in the foil well are positioned under the seat of each side of the seat with an opening in the side doors (41, 42) about ten centimeters below the level of the pilot's buttocks which allows the pilot to operate the actuating triggers while remaining seated and positioning his hands under the level of her buttocks.
