A fin for use on a surfboard or another watercraft comprising a fin section that can be releasably coupled to the base of the fin, and the fin section can be slidably adjusted relative to the base in a direction towards the leading edge or the trailing edge of the fin. Following adjustment, the position of the fin section can be secured to the base with one or more locking means.

A fin arrangement for a surf craft includes a base coupling portion to couple the fin arrangement to the surf craft; a central fin having a central fin base portion, the central fin coupled to the base coupling portion to extend substantially perpendicularly away from an underside of the surf craft; a first side fin coupled to the central fin base portion and extending away from the central fin and the surf craft at a first acute angle to the central fin; and a second side fin coupled to the central fin base portion and extending away from the central fin and the surf craft at a second acute angle to the central fin, the second acute angle being substantially the same as the first acute angle, and a projecting lobe extending rearwardly from the base of the central fin.

An Adjustable Fin Assembly for Watercraft. The modular assembly should be design to be incorporated into a surfboard or other watercraft during fabrication of the craft. Each fin assembly is designed to allow for the watercraft user or fabricator to attach a conventional fin element to it. The fin assembly enables the user to adjust the fin position longitudinally as well as laterally relative to the watercraft. The housings each include a set screw or other component that can be loosened and tightened by the user in order to reposition the fin and then fix it in the new position. The conventional fin attaches to a sliding plate that is housed within a housing, wherein the movement of the sliding plate relative to the housing is prevented by engagement with the set screw.

A pontoon for providing buoyant force to a floating craft comprises a barrel having front and rear ends and a fin extending outwardly from an outer surface of the barrel. The fin includes a first portion and a second portion positioned rearwardly of the first portion. The first portion extends at least generally parallel with or coincident with a lateral, horizontally extending centerline of the barrel. In order to enhance stability, improve handling, and/or inhibit motor cavitation, the second portion is inclined downwardly and rearwardly relative to the rear end of the first portion. Also disclosed is a pontoon boat fitted with fins on the pontoons and/or on the transom.

This relates to vessels in general, but in particular to displacement vessels designed to be exposed from low to medium to high waves. Both for comfort of persons, animals or fragile goods, steady sailing is preferred, without causing the waves slamming in on the vessel hull or excessive pitching of the vessel. This is also the case for service and supply vessels performing operations in relation to offshore or subsea installations. To obtain a solution to the aforementioned issues the present invention provides a vessel, wherein a stern of the vessel extend below a design waterline (Tdwl), and wherein opposite side surfaces of the stern, when seen in an opposite direction of the vessels primary sailing direction, form an acute angle under and above the design waterline (Tdwl) to decrease the vessels displacement in the rear end and are adjoined along at a line of symmetry forming a stern centerline.

The present invention relates to the design of seagoing vessels and can be used for most hull types from slow-moving ships and barges to high-speed ships and boats that are operated up to planing speed, and also for sailing boats. The invention relates to the design of the vessel's forepart and relates to a device that reduces the vessel's wave resistance within a wide speed range, and also reduces or eliminates spray and wave-breaking resistance. The device comprises a body that is fully or partly submerged in a mass of water and positioned at the bow area, the body working in interaction with the hull behind. The body is designed and positioned such that it displaces oncoming water mass in the vertical plane and then leads the water mass that passes on the top surface of the body away from and/or parallel to the bow area, such the hull itself, behind the body, displaces oncoming water masses to the least possible extent. A reduced resistance to forward movement from the vessel is thus obtained.

A vehicle front structure includes a front window glass, a washer nozzle, a cowl, and plate members. The front window glass includes angle-of-view areas at its upper portions. The angle-of-view areas cover angles of view of left and right imagers disposed on an interior of a vehicle. The washer nozzle ejects a washer fluid to an outer surface of the front window glass. The cowl is recessed and extends in a vehicle width direction between the front window glass and a front hood. The plate members stand erect in the cowl and extend in a vehicle front-rear direction. The plate members are disposed at least one at each outer side, in the vehicle width direction, of a widthwise center of the vehicle. The plate members extend toward an area interposed between outer edges of the angle-of-view areas in the vehicle width direction in a plan view of the vehicle.

A standing torso support apparatus for paddleboards has a base removably attachable to a paddleboard, an adjustable-height support leg extending upward from the base, and a torso support attached to the top of the support leg. A user may lean against the torso support to aid in balance or power.

A water diverter for outboard marine motors is presented. In one embodiment, the water diverter is adapted to be secured to a transom bracket which includes a portion adapted to be mounted on a boat transom. The water diverter includes a body and a bracket. The body has a horizontal deflection plate with a triangular shape. Two vertical deflection plates extend upward along the edges of the horizontal deflection plate. The bracket includes a horizontal mounting surface having a triangular shape. Two vertical attachment walls extend downward along the sides of the horizontal mounting surface. The bracket is sized to fit within the body with alignment of attachment openings of the vertical deflection plates and attachment holes of the vertical attachment walls determining a fastener-based selectively adjustable vertical displacement between the horizontal deflection plate and the horizontal mounting surface.
