Actually, it could. The food needed for that length of time can't weigh
that much, especially if it's all freeze dried. The web site said the ship
weighed 400 tons. Out of that 400 tons, the site says it contains "57
tonnes of food and 80 tonnes of oxygen". You don't think 57 tons is enough
food to last 8 people 6 years? That's 3.25 kg per day (over 7 pounds).

3.25kg/man-day (which is indeed what that number translates to) is loads.
The average human requirement is 0.62kg of freeze-dried food, plus a
smidgen for packaging, plus a couple of kg of water for rehydration and
preparation. And you'll have to recycle water anyway -- washing dishes,
people, and clothes just takes too much of it -- so it doesn't figure into
long-term supplies much.
