Abstract

The present invention relates to a marine vessel comprising a hull (2) with a centre-line (21), a propulsion system, and a keel arrangement. In order to enhance the manoeuvring qualities of the marine vessel, the propulsion system comprises an omni-directional propulsion unit and the keel arrangement comprises an active keel unit (3) with a first active keel member (31) and a second active keel member (32).
