Chandler

Chandler: Chandler, which is etymologically related to candle, originally referred to someone who made or sold candles. However, with time, the most popular use was a ship chandler who sold supplies to provision ships with all the prerequisites for a ocean voyage. These days, a chandler might be any retailer who sells provisions as in a backpacking chandler or a mountaineering chandler. The chandler stocks equipment more than consumables: gear, not food.

I would run errands for ship chandlers, or sit by a wall somewhere and read The Pirate's Daughter.

We're completely self-sufficient with regard to power and everything else aboard except for chandlerage and supplies.
