Search and rescue operators in the Battle of the Atlantic were puzzled to find victims floating righted up, with their faces well above the water, not bearing any distinctive trauma injuries, and drowned before the hypothermia time scales. Beside sudden cardiac arrest, cold water and diving reflexes, one of the most perplexing explanations was found in the water particles that saturate the space between the surface and one metre of height in gale winds, flooding the airways and suffocating the victims.
Aside, the millions of tiny particles and gases blown by breaking waves and windrift spray contain dissolved sodium chloride (NaCl) or ordinary table salt, and hydrogen chloride (HCl). Both of these molecules are highly soluble, and as they evaporate, after causing severe irritation, may dissolve as gases into the lungs producing chemical and biological changes that may cause a rapidly deteriorating condition without clear warning between one and forty-eight hours after initial rescue procedures, creating symptoms similar to pneumonia, that is, the flooding of the lungs with pulmonary fluids.
To help in the prevention of drowning by spray particles which in gale winds or breaking surf, may instantly forbid breathing, as well as secondary drowning, spray hoods carried in small pouches may be deployed and attached to the buoyancy aids to cover the face and protect the airways when in the water, allowing the wearer to breathe.
Normally, hoods have ventilation holes that prevent condensation allowing you to keep visual contact.
Not rare between yachters, a time ago Palm was suggested by one of their field testers to incorporate a light deployable mesh screen inside their jacket’s hoods. The proposal was rejected as it was deemed unlikely that users might find themselves in the situation to need it.
I think otherwise. This would be a feature that adding negligible weight to the garment, would be a welcome safety improvement.
