Definitions

• planks which are very airy and do not oblige the user to change the feet of position during changes of direction, is on the other hand very delicate to handle because of the very sharp sails on both sides and is moreover reserved for a high technical level because that it is only effective in strong wind conditions.
• the boards In both cases the boards have symmetrical edges and curvatures with respect to the longitudinal axis.
• the present invention makes it possible to remedy the disadvantages mentioned above; taking into account the particularities of larpr ⁇ pulsi ⁇ n-by a flying wing, this new board optimizes the-yield at all ⁇ Hures thanks to ⁇ new solutions.
• the board is ⁇ ymetric ⁇ along the transverse axis, or axernineur. It can therefore move forward to the right or towards
• the outer lines are also different on both sides of the longitudinal axis as shown in Fig.1.
• the “windward” side has tighter lines than the “leeward” side.
• the side “in the wind” in fact, essentially used to direct the board to the wind during upwind ascents, has very tight lines, with very little rounding in the center and more or less square ends.
• the side “downwind” is on the contrary well rounded, with a marked central curvature and well tucked ends in order to facilitate the changes of direction and the handling in general.
• the two halves of the hull on each side of the longitudinal axis are also different; the “windward” side is more taut, its section is flat or concave with possibly nozzles towards the outside edge, allowing better channeling of the flows and favoring the heading.
• the "leeward” side is more raised, convex towards the ends with a flat central section, concave or with nozzles, depending on the degree of directional stability sought, Figure 2 illustrates this principle.
• the daggerboards necessary for an effective windward ascent, can be placed in different configurations, but always with a centerboard at each end of the board and one or more daggerboards placed on the "windward" side.
• Figure 1 shows in front view the hull of the board.
• the “leeward” side (2) is characterized by a curvature markedly more accentuated in the center and by rounded ends.
• the center line (3) defines the line for changing the curvature of the hull section and is not necessarily located in the middle of the board.
• Sections A-A 'and B-B' show the two very different half-hulls: a concave “windward” part (6) with a nozzle on the edge (8) and a flat or convex “leeward” part (5).
• Section B-B ' also shows the difference between the edge or “rail” “in the wind” (4) which is low and acute and the edge “in the wind” which is high, square or rounded on its central part (7).
• Figure 2 shows the board in side view, with reference to this drawing, we can distinguish the curvature of the top of the board (9) or "bridge” and the center line (3).
• Figure 3 shows the basic layout of the fins or fins; a first pair is positioned on the center line, at each end of the board (10), the other pair, closer to the middle of the board, is located near the “windward” edge of the latter (11).
• Figure 4 shows a side view of this arrangement where we distinguish the pair of middle fins (10) and the side pair (11).
