As the usage of R/V Onrust increased, it was noted that the vessel needed additional space if larger, bulkier and heavier equipment were to be deployed.  Additionally, larger science parties on mult-day cruises would benefit from larger amount of space on the deck.  in March of 1990, the R/V Onrust entered the Brooklyn Navy Yard to have the stern extended and the length of the ship increased.   The work was completed within a month.

The image on the right shows the profile of the R/V Onrust before (top image) and after (bottom image) the work in the Navy Yard.
