The Makar-class survey catamarans are a series of six 500 ton steel hull/aluminium superstructure Hydrographic Survey Catamarans being built by Alcock Ashdown (Gujarat) Ltd at its Bhavnagar shipyard for the Indian Navy. The ships are designed by an Australian naval architecture firm Sea Transport Solutions, which is based on Queensland's Gold Coast. The deal was canceled due to the extensive delays as the Navy was not satisfied with the timeline[6] and a fresh award for construction of another class of survey vessels to the GRSE has also been undertaken.[7]
