In terms of potable water, what is a critical factor for planning?

Daily water usage needs are essential for planning potable water requirements on a sailing trip because they help determine how much water each person on board will need for drinking, cooking, and hygiene purposes. By understanding these needs, sailors can calculate the total amount of water required for the duration of the trip based on the number of passengers and the length of the trip. This assessment ensures that adequate supplies are onboard to prevent dehydration and to maintain health and safety during the journey.

While the amount of passengers and the length of the trip are relevant factors, daily water usage needs give insight into the specifics of how much water should be stored. Weather conditions can also influence overall planning, such as increased water needs in hot temperatures. However, without a clear understanding of daily consumption, these factors alone will not provide an accurate measure of potable water needs for the duration of the sailing experience.
