摘要： The invention is related to boatbuilding and may be used in construction and modernisation of high-speed monohull motor seagoing boats, where a single hull is used, which is moving in a surfing on a water cushion mode.
Stabilised hull of a monohull motor boat, which is using a surfing glide on a water cushion, with the deeply submerged displacement bearing blade, with a hull of a total width of not more than 50% of its length, which, in its lower part over its entire length, has a descending shape of its bottom surface in the direction bow-to-stern, where the bow is elevated up to the distance from the waterline, corresponding to at least 25% of the hull's width, and under the bow is a high wave-piercing stem. Wherein, in the front 40% of the hull's length, the bottom surface has a descending shape, which smoothly flows into the bottom surface of the stern part of the hull, and has an angle of descent in relation to the waterline at zero speed of at least 5 degrees, in the rear 60% of the hull's length, the bottom surface has a descending shape, and the angle of descent in relation to the waterline at zero speed of not more than 5 degrees, while it has an almost flat shape in its cross section, and is submerged by 70% or more of its length below the waterline, where the submerged part becomes the "surfing surface", which is gliding, during the boat's movement, on a water cushion, and carrying not more than 70% of the boat's fully loaded weight.
The hull is made with a longitudinally positioned located underneath the bottom surface, symmetrical with respect to the boat's centerline, and commensurate with its length, vertically oriented, deeply submerged displacement bearing blade of narrow shape and of low wave / hydrodynamic resistance; wherein the ratio of the length to the width of the bearing blade of at least 20 times, with the displacement of the bearing blade corresponding to 30-50% of the boat's fully loaded weight, and with its height (excluding the stem) of not less than 20% of the maximum width of the hull, wherein ensuring a deep submersion of the bottom edge of the bearing blade in relation to the waterline. The bearing blade is made with wave-piercing lines, with a high wave-piercing stem, reaching by its height the bow end of the bottom surface of the hull, with the sharp rear and front lines, and the smooth middle lines; and has a triangular cross section over its entire length, with the most acute angle at its bottom; and the maximum width of the bearing blade is located within 40-60% of its length, which determines the centre of the displacement of the bearing blade within 40-60% of its length, in its upper third.
The controllable hull of the displacement boat stabilised for sea waves conditions and gliding on the water cushion, opens up broad prospects for the construction of the high-speed seagoing boats. First of all, this is a fundamental improvement in stability of the movement, and the absence of rolling / pitching and yawing in the open Sea, as well as increase in a carrying freight capacity and improvement in the fuel economy, as compared to the planing hulls.-

摘要： The present invention relates to an attachment apparatus (2) for attachment of a keel (4) to a hull base (6) of a boat. The apparatus for attachment (2) comprises an elongated sheet-shaped element (10), extending in one propagation plane (P), on which the keel (4) is intended to be attached between the short ends (14, 16) of the elongated element. The sheet-shaped element (10) is arranged to be attached to the hull base (6) of the boat by means of front attachments (20) and by means of rear attachments (22) , and that the sheet-shaped element (10) is designed to elastically deflect from said propagation plane (P) when the element (10) is subjected to a torque around the attachment position (14) of the keel in a plane perpendicular (V) against said propagation plane (P) . The present invention also relates to an arrangement (8) respectively a sailboat comprising the attachment apparatus (2).

摘要： A vessel (10) for travelling on water comprises a hull means (20) and a keel (30) comprising a member (34) depending from the hull means, the member (34) comprising two limbs (44) each depending from a respective lateral side of the hull means (20), the two limbs (44) defining at least in part an enclosed flow path extending in a bow to stern direction, the enclosed flow path being configured to allow water incident on the vessel to flow over inner and outer surfaces of the limbs (44a, 44b). The limbs (44) each have a zero-lift surface which is angled to generate in use a component of hydrodynamic force directed away from the enclosed flow path when there is a net flow of water along the enclosed flow path.

摘要： L'embarcation comporte une quille (3) essentiellement constituée par une capacité allongée (4) formée en un matériau souple déformable et étanche à l'eau. Une ouverture d'admission d'eau (6) est ménagée dans la paroi de cette capacité allongée (4), tournée vers la proue de l'embarcation et maintenue ouverte, pour faire régner dans cette capacité allongée (4) la pression d'arrêt de l'eau dès que l'embarcation est en mouvement vers l'avant, ladite capacité allongée (4) se trouvant alors au moins partiellement remplie d'eau.

摘要： A fin suitable for a surf board, dinghy or wind sailing board or the like is formed of a resiliently flexible material such as a solid urethane and reinforced with a stiffening insert (11) which incorporates means (16, 17, 18) for attachment to the surf board or the like.
Interconnection of the fin with the reinforcing stiffener (11) is provided by means of openings (30 to 33) in the stiffener (11) to which the fin material extends, and projections (34,35) extending from the side wall of the stiffener (11) which are exposed by the fin material and lie flush with its surface.
A substantial trailing edge portion (24) and the tip (28) of the fin are unsupported by the stiffener (11) so that these can flex to reduce vortices in use and potential damage which might be caused upon impact of the fin against a solid object or another person.摘要翻译： 适用于冲浪板，小艇或风帆板等的翅片由弹性柔性材料（例如固体聚氨酯）形成，并用加固插入件（11）加强，所述加强插入件（11）包括用于附接到...的装置（16,17,18） 冲浪板等。 翅片与加强加强件（11）的互连通过翅片材料延伸的加强件（11）中的开口（30至33）提供，以及从加强件的侧壁延伸的突起（34,35） （11），其被翅片材料暴露并与其表面齐平。 大的后缘部分（24）和翅片的尖端（28）不受加强件（11）支撑，使得它们可以弯曲以减少使用中的涡流和在翅片抵抗固体时撞击时可能引起的潜在损伤 对象或另一个人。
