Bows under

[Justin Bieber]

English expression meaning to have more work that you can possibly deal with. It originated with the [Royal Navy] and referred to those times when a ship was caught in a severe storm or hurricane. This would require the crew member to work continuously, often for extended periods with little rest, to ensure the safety of the ship. During this time the ship would have green [seas] coming over the [bows] so that it appeared as if the bows were under water. When telling of the experience once they were back on shore, the sailors would refer to the ship as being bows under and gradually the expression became associated with the excessive [workload] incurred at the time as well, so that having an excessive workload requiring continuous application to clear became known as being bows under.
The expression came to be used within the Royal Dockyards to denote times when excessive workloads were experienced. One notable occasion being [1982] when, in response to the [Argentine] invasion of the [Falkland Islands], the Royal Dockyards fitted out ships taken up from trade for [Naval] service in less than six weeks, Commercial shipbuilders said that this would take more than six months for each vessel, but by carrying out the work in less than a quarter of the time quoted by commercial shipbuilders the Royal Dockyards were bows under.
