In extreme circumstances, one man can be catergorized as a failboat in and of his/her self.
Pictures of capsized or rolled boats usually shown as an example of what happens when the crew does something.
It is in reference to "fail boat" pictures on the internet (google image search it) which ususally depict a boat that is sinking or capsized with the words fail boat underneath.
If this were to be put on a scale of failure then it would be just below the term "epic fail".
"All aboard the Fail Boat!"
"Your shipment of Fail has come in!"
If your on instant messanging or emailing then you would usually attach a picture too because the joke is rooted in the pictures and is funnier if you use a different one each time.
Hey lets all jump on to this noobs fail boat and take a ride down Fail Lake.
CAPTION: Failboat always delivers
