This year’s voyage, organised by the non-profit educational foundation Amistad America Inc, will retrace the slave industry triangle with stops at more than a dozen Atlantic ports that played a significant role in the trade and reflect today’s social, political and cultural diversity.

Amistad number two was built at Mystic Seaport Museum, Mystic, Connecticut USA between 1998 and 2000. Caterpillar supported the initiative by donating two Cat 3304B marine engines rated 104 kW (140 hp) at 2,000 rpm to Amistad America, Inc.

'Since the schooner left New Haven, Connecticut USA on 21 June the Caterpillar engines have given us a smooth journey across the ocean and off the UK', said Amistad engineer Ben Clarkson

Amistad’s next port of call will be Lisbon, Portugal, then on to West Africa. Further information about the Amistad Atlantic Freedom Tour can be found at www.amistadamerica.org.
