Fresh water economy aboard ship may dictate using as little water as possible. Hence, the navy shower; wet down, turn off the water, soap up, turn the shower on to rinse off. If a ship's fresh water making device, the evaporators (evaps) have problems, a ship may experience "water hours" in which no showers are allowed except at select times. Generally, the smaller the ship the more experience the crew has with Navy showers.
