The main land passenger vessel service is available almost every week. Besides the inter island ferry service is also available. There is anchorage close to the lagoon entrance off north end and also the common anchorage between Kadmath and Amini islands. The boats take about half an hour from anchorage to jetty. Amini is the principal island of the northern group islands. Amini island retains its importance in terms of population and is Taluk head quarters.  

The Lighthouse is situated on the southern tip of the island and is about 2 km from jetty. There is no evidence of any earlier lighthouse on the island. Amini had a sizeable traffic of sailing vessels to mainland ports of Mangalore, Cannanore and Beypore for the export of copra and coir and import of Rice and other commodities. These country crafts were commanded by the islanders who were quite expert navigators. However there was a flag staff erected on the north east end of island in the 19th century. Subsequently an oil lamp used to be hoisted from the same mast in the beginning of 20th century. After the Lighthouses were established on different islands the sailings became more safe and less time consuming. 

 In the year 1984 the G.I. trestle tower was erected on its Southern tip so that together with Lighthouse a Kadamath Island the two Lighthouses could mark the atoll. The trestle tower was supplied by M/s Kerala Electrical & Allied Industrie Ltd, Cochin. The DA gas equipment with 300mm optic from LH work shop, Madras, was installed on this tower and was commissioned on 27thMay1984. The DA gas equipment was replaced by halogen lamp, and ‘Jyoti Punj’ flasher operating on Batteries charged by solar panels by the composite Cochin-Jamnagar team. It was commissioned on 1stNovember 1995.
