Abstract
A stabilizer device for a watercraft with a hull. The stabilizer device includes a fin blade with a fin base, a fin tip, a leading edge, and a trailing edge, wherein a blade forward direction (fb) is defined from the trailing edge to the leading edge at the fin base, wherein the fin blade comprises a first fin connection element connected to the fin base in a first connection point a hull element arranged to be fixed to the hull with a hull forward direction (fh) in a forward direction of the hull, and a fin blade displacement portion connected to the first fin connection element and the hull element and arranged for displacing the first fin connection point a first displacement, in parallel with a lower surface of the hull, and perpendicular to the hull forward direction (fh).

A stabilizer device for a watercraft with a hull, wherein the stabilizer device comprises;
- a fin blade with a fin base, a fin tip, a leading edge, and a trailing edge, wherein a blade forward direction is defined from the trailing edge to the leading edge at the fin base, wherein the fin blade comprises a first fin connection element connected to the fin base at a first fin connection point;
- a hull element arranged to be fixed to the hull with a hull forward direction in a forward direction of the hull;
- and
- a fin blade displacement portion connected to the first fin connection element and the hull element and arranged for displacing the first fin connection point a first displacement, in parallel with a lower surface of the hull, and perpendicular to the hull forward direction, wherein the fin blade displacement portion comprises a first link element interconnecting the hull element and the first fin connection element and a fin displacement actuator arranged to reversibly pivot the first link element,
- wherein the first fin connection element is an axle rotationally fixed to the fin base, and extending out of the fin base, wherein the fin blade displacement portion is arranged for pivoting the first fin connection element about a first axis at a rotational angle, and wherein the hull element is connected to the fin base only in the first connection point.
A stabilizer device for a watercraft with a hull, wherein the stabilizer device comprises;
- a fin blade with a fin base, a fin tip, a leading edge, and a trailing edge, wherein a blade forward direction is defined from the trailing edge to the leading edge at the fin base, wherein the fin blade comprises a first fin connection element connected to the fin base at a first fin connection point;
- a hull element arranged to be fixed to the hull with a hull forward direction in a forward direction of the hull;
- and
- a fin blade displacement portion connected to the first fin connection element and the hull element and arranged for displacing the first fin connection point a first displacement, in parallel with a lower surface of the hull, and perpendicular to the hull forward direction, wherein the fin blade displacement portion comprises a first link element interconnecting the hull element and the first fin connection element and a fin displacement actuator arranged to reversibly pivot the first link element,
- wherein said first link element is arranged to pivot about a second axis that is fixed relative the hull element and further perpendicular to the lower surface, and
- wherein the first link element is a wheel with a rotational axis coaxial with the second axis, wherein the first fin connection element is connected to a periphery of the wheel.
A stabilizer device for a watercraft with a hull, wherein the stabilizer device comprises;
- a fin blade with a fin base, a fin tip, a leading edge, and a trailing edge, wherein a blade forward direction is defined from the trailing edge to the leading edge at the fin base, wherein the fin blade comprises a first fin connection element connected to the fin base at a first fin connection point;
- a hull element arranged to be fixed to the hull with a hull forward direction in a forward direction of the hull;
- a fin blade displacement portion connected to the first fin connection element and the hull element and arranged for displacing the first fin connection point a first displacement, in parallel with a lower surface of the hull, and perpendicular to the hull forward direction, wherein the fin blade displacement portion comprises a first link element interconnecting the hull element and the first fin connection element and a fin displacement actuator arranged to reversibly pivot the first link element;
- a second link element;
- and
- a second fin connection element that is extending from the fin base and fixed in a lateral direction relative the fin base,
- wherein the second link element interconnects the hull element and the second fin connection element, and
- wherein the fin blade displacement portion is further arranged for displacing the second fin connection element and the fin base laterally relative the hull forward direction.
