The design includes passive stabilisers - a pair of 18 kg "fish" (flopper stoppers) slung from booms, trawler style. We chose these over other types of stabilisers (activated fin or bilge keel) as they are more efficient at all speeds & headings & cost effective. They also can be used at anchor with a different attachment.
