I once ran out of propane to run our stove and make coffee on day two of a 5 day offshore passage, about 80 miles from any land. Facing immediate crew mutiny, we made all sail for the nearest port of call. Continuing without coffee was deemed to be complete madness.

After that, redundant coffee making systems were installed (inverter, small electric coffee maker) for similar emergencies. Competent cruising captains know that all essential systems need at least one redundant backup. Coffee is absolutely essential. Beer too, running out that would be a flogging offense on my ship.
