Custom exhaust systems designed, engineered and manufactured by Manuflex Ltd. in partnership with Centek Industries are providing sound attenuation aboard two fast pilot launches built by Goodchild Marine of the United Kingdom for Estuary Services, Ltd. Both vessels operate from Ramsgate, supporting Thames pilots in the busy Southern North Sea and Thames estuary. Estuary Elan was the first of its innovative design by French Naval Architect Pantocarene to be built in the UK by Goodchild Marine.
