Prowler, those are medikits, and the system has basically infinite food and water with a fridge, completely unrealistic.

Being able to haul food, and needing to drink water and eat food would likely add more to the game, especially on longer voyages(slow food and water drain but lots of resource used at once would disturb the gameplay less while still adding more things to add to ships)
