Abstract
A sailing method and a sailing boat (1) are designed for low or even non-drift sailing, wherein the total power provided by the sail (5) is established, after which the keel (3) is adjusted in terms of its effective surface and/or its curvature and/or the shape of its profile and/or its setting angle in relation to the boat's hull, possibly taking into account the water current and the weight of the boat, in order to produce an optimized counteracting force. To this end the keel (3) is designed as a multi-section, unballasted fin keel (33) which can be completely retracted into the boat's hull (2) and can be pivoted relative to the centerline of the boat (10), and the sections (34, 37, 38) of which are fitted together via hinges (35, 39) in order to produce a variable curvature.
