Super cool story! I remember the Rainbow Warrior well. I know everyone doesn't love Seashepard for their strategies but I think they're legends.

They're a rag tag bunch of 'sea gypsies' off exploring - it's quite mental what they do, and at one stage Seashepard help them out.
Sea Gypsies looks cool we will definitely be checking it out.
