The latest witness at the trial of a former BC ferry worker accused of causing the deaths of two people says numerous changes have been made since the 2006 sinking of the Queen of the North vessel.

Rory Green is a deck hand and junior officer who worked on the doomed ship.

He says the rules followed in March of 2006 were much more grey than they are today.

He says, "Things have changed so much. Now, we have to sign off on every little thing."

Having worked with the man on trial --Karl Lilgert-- Green says he was good at his job, but Green doesn't remember experiencing any technical problems while on the Queen of the North.

Lilgert is on trial for criminal negligence causing the deaths of two passengers.
