What are the unwritten rules of a yacht charter?

The unwritten rules of a yacht charter: shoes off, conserve fresh water, don’t crowd the crew, and tip at the end. Shoes off is the most-violated rule; deck scuffs are why. Fresh water is finite — the watermaker refills the tank slowly, and a 20-minute shower for one guest drains the supply for the rest. Two-minute showers and short rinses are standard. Don’t crowd the crew while they’re working — the galley, helm station, and engine room are off-limits unless invited. Don’t ask the chef to cook something not on the preference sheet without a day’s notice. Smoking is exterior-decks-only, downwind. Tip at the end of the charter in cash to the captain. Pictures of the crew without asking are a no-go. Yacht etiquette basics covers the rest.
