For what it's worth when i was cross decking from the Aladin at 17N on to that fine figure of a vessel the M5 (no really it should be called the Hilton of the High Seas, NOT! ) at the end of my last rotation out there, there was a female also cross decking from the M5 and on to the Aladin, very definitely doing MARSEC given what she was wearing, i would hazard a guess and say that she looked like she was possibly EX US Military as she had a bit of a penchant for Digi Cam and 5.11's but it was funny to see all the guys on the Aladin all suddenly start doing some phys on the top deck once she was on there
At first I thought we'd been on the same trip...
I also took the great M5 cruise from 17N to Djibouti with a female onboard, but she was part of the Aladin finnish crew. (Could be a solution for Kelly23 lol).
I did phys too I must admit
