I can't bear to take any of those precious little items off shelfs, squirreled away in drawers or taped to bulkheads. A family boat has short(in years) but potent history.

And 'Strike Anywhere" wooden stick matches. Stove, fireplace, candles, use them all the time. We couldn't leave without strike anywhere matches(lighters are too complex and prone to failure).

Oh, and an ice pick. Sailing without an ice pick? No way.
