At what water temperature is a dry suit ensemble worn at the CO's discretion?

A dry suit ensemble is typically worn in water temperatures between 60 and 70 degrees Fahrenheit at the discretion of the commanding officer (CO). This temperature range is significant because it represents a critical threshold where the risk of hypothermia increases, especially during prolonged exposure to cold water conditions.

In the light of safety protocols and the need to protect swimmers from the adverse effects of cold water, the use of a dry suit becomes a prudent decision. The CO's discretion allows for flexibility depending on additional factors, such as wind chill or individual factors related to the swimmers' abilities and acclimatization to cold water.

Other temperature ranges provided do not align with the typical guidelines on when a dry suit is recommended, as they either fall below the standard threshold where immersions in water temperatures under 60 degrees necessitate a dry suit for safety or exceed it, which usually does not require such thermal protection.
