Four Bangladeshi fishing boats - Allardan, Farhad, Nahim and Ma Ganga - got adrift in Indian waters due to mechanical failure post-depression in northern Bay of Bengal on August 17 and 18.
Two of the four stranded boats were sighted at 35 nautical miles south of Sagar lighthouse by a Coast Guard aircraft, officials said.
The other two fishing boats were sighted stranded inside the creek by a Coast Guard surveillance aircraft on Aug 18.
The fishing boats had departed from Maipur and Cox Bazaar in Bangladesh and were caught in the cyclonic winds that hit the Bay of Bengal.
