After a spell in the Garvel drydock, the North Lighthouse Board's POLE STAR was this afternoon undergoing engine trials in the James Watt Dock, as can be seen here. Now looking very smart, during her spell in the Garvel yard her hull was completely shot-blasted back to the bare steel, and fully repainted. POLE STAR dates from 2000, and was built at Port Glasgow by Ferguson Shipbuilders. Main propulsion is by a diesel-electric system driving two Kamewa Aquamaster azimuthing propeller units. These, combined with twin bow thrusters, provide her with very accurate dynamic positioning. POLE STAR is 51.52 metres long, and is 1,174 gross tons. Her main role is buoy handling around the coasts of Scotland and the Isle of Man.
