  Well, we are going out to sea later this week! Although after that we will be in a dry dock for 6 months being refitted and having some essential maintenance.
  
  We have just been away for the last 6 months, doing anti-piracy operations. Ships spend a lot more time at sea than they used to because there are less of them and just as many jobs to do.
