American Sailing Association (ASA) 104 Practice Exam

When out on a boat, it's essential to manage water resources carefully, particularly for bathing and personal hygiene. The recommended amount of water for bathing per person per day while on a boat is typically around 5 gallons. This amount allows for a reasonable wash, ensuring that individuals can maintain personal hygiene without overly depleting the water supply, which is limited on a vessel.

Using around 5 gallons per person balances the need for cleanliness with practical limitations of storage and conservation practices on board. It is important to be mindful of this consumption to ensure there is sufficient water for not just bathing, but also cooking, drinking, and other daily activities while at sea.
