This paper constitutes an effort to substantiate whether there are certain nationalities of crews which are for ethnic and / or cultural reasons more (or less) vulnerable to fall victims of Pirates off Somalia. Such groups (if there are any) in effect indirectly ‘support’ Somali piracy and for this reason they are being re-ferred to throughout the paper as “Passively Supportive Crews”. The method (and the rational) in use within this paper is straightforward. Over a three and a half year period (2007 – June/2010) an analysis is being conducted of all the reported (to the I.M.O. and I.M.B.) attacks in the region off Somalia. The analysis focuses on the crew composition of the attacked vessels with special interest cast upon those Ships (meaning the crews) which eventually succumbed to the pirates and were in the end seajacked.
