Abstract

The application relates to a kit for installing hydrofoils (22, 32, 45, 55) for a boat (1). The kit for installing hydrofoils (22, 32, 45, 55) includes: at least one support block (21, 31); and at least two hydrofoil arms (22, 32) each having a hydrofoil (24, 34). The or each support block (21, 31) includes: at least one adapter part shaped to cooperate with a structural element (15, 13) of the boat (1) and to be attached thereto, the adapter part providing a reference plane for the hydrofoil arm(s); and a plate on which at least one of the hydrofoil arms (22, 32) is intended to be mounted, the plate being capable of being mounted on the adapter part along the reference plane.

IPC Classes  ?

• B63B 1/24 - Hydrodynamic or hydrostatic features of hulls or of hydrofoils deriving additional lift from hydrodynamic forces of hydrofoil type
• B63B 1/28 - Hydrodynamic or hydrostatic features of hulls or of hydrofoils deriving additional lift from hydrodynamic forces of hydrofoil type with movable hydrofoils

Abstract

The invention relates to an assembly of a mounting system (43) and rudder (44) for mounting the rudder to the hull (11) of a boat (1). The assembly comprises: a frame (442) which is mounted on the hull (11) from a first mounting element and a second mounting element; and a rudder body (441) which is slidably mounted in the frame (442) to allow adjustment of the depth of the rudder (44). The rudder (44) has a hydrofoil (45). The rudder body supports the hydrofoil (45) at one of the ends of said rudder body, and wherein the rudder body is suitable for being arranged in the frame (442) with either the hydrofoil (45) oriented upwards, i.e. above a waterline of the boat (1), or the hydrofoil (45) oriented downwards, i.e. below a waterline of the boat (1).
