MREs are only meant to be eaten for up to three weeks, but casting caution to the winds . . . At four MREs per day (510 to 740 grams ea.), plus six liters of fresh water, one week supply would weigh 60 kg. Making five knots for 10 hours per day would be generous. At that blistering velocity, 4500nm would take thirteen weeks, needing 780kg of food & water. Which would prevent his wheel from turning. Of course, if he knew how to plot a course, he'd have the winds at his back.
