I can only speak about the first flight 688's on this one.. While we didn't notice it it may have smelled like it after a couple of months of being underwater. I will tell you that when we did our shell back ceremony that boat stank and no matter how many times we cleaned it before pulling into Singapore (yes we ran the diesel to help vent the boat out and try to change the smell inside of the boat) but it was for no use, to this day when I think about it I can still smell that stench and see the look on the distinguished guest faces when they came onboard when we pulled in.
