From the sound of things, you're going to need some damned<em>amazing</em>luck to find him to put it on.<br/><br/>In an amusing twist, the one rank bonus/ability that I went "I need one of those" was actually Ship's Steward, however, might I suggest changing it? Namely, to 'doubles the length of time food supplies can last, two such effects become a triple' or something, as Extended Supply Vaults doubles the length of time supplies last and gives a bonus to repair, and I remember one ship hull has a 'cramped' special rule which halves the time.
