It was noted steering instability has been experienced particularly with large bulk carriers and mammoth tankers having blunt hull forms; tendency has been apparent in tankers with length/breadth ratio of less than 7 to 1 and in ships with smaller length/breadth than 6 to 1; head of Decca Arkas operational research team, M.Bech, has devised and patented method of modifying existing Arkas autopilot and manual steering systems whereby vessels with unstable or marginally unstable steering characteristics can be electronically cured of defect; actual patent application is generally shown.
