As the ship was intended to function as a floating, self-contained community, it was stocked with victuals (food and drink) that could sustain its inhabitants for extended periods of time. The casks used for storage on the "Mary Rose" have been compared with those from a wreck of a trade vessel from the 1560s and have revealed that they were of better quality, more robust and reliable, an indication that supplies for the Tudor navy were given high priority, and their requirements set a high standard for cask manufacturing at the time.
