Take an Official State-Approved Boater Safety Course
From November through May, New York enforces additional personal flotation device (PFD) and safety requirements due to cold water conditions. Water temperatures during this period pose severe hypothermia risks. Cold water can cause loss of consciousness in minutes. Additional flotation equipment, immersion suits, and rescue equipment are strongly recommended or required on some vessels during cold water season.

From November through May, New York waterways experience dangerously cold water temperatures. Water in this period typically ranges from 35-50°F depending on location and specific date within the season.
These cold water conditions create unique hazards and legal considerations. Enhanced safety requirements apply during the cold water season, recognizing that cold water immersion can cause loss of consciousness and death in minutes rather than hours.
Water temperature determines survival time in cold water immersion. Survival curves demonstrate:
– 35°F water: 15-30 minutes of consciousness; potential for sudden incapacity
– 40°F water: 30-60 minutes of consciousness; increasingly difficult to help yourself
– 50°F water: 1-2 hours of consciousness; still dangerous, especially for older boaters
Cold water immersion causes several dangerous effects:
– Cold shock: Involuntary gasping and inhalation of water
– Muscle failure: Inability to swim or climb out of water
– Hypothermia: Core body temperature drops, causing confusion and loss of consciousness
– Afterdrop: Continued core temperature loss even after rescue
A person in cold water loses manual dexterity in minutes, making it impossible to fasten life jackets, deploy flares, or operate communications equipment.
During cold water season, wearing PFDs becomes even more critical. Standard New York PFD requirements continue to apply:
– One PFD per person must be aboard
– Children under 10 must wear PFDs at all times
However, legal interpretation during cold water season emphasizes that all boaters, not just children, should wear PFDs. Insurance companies and safety organizations consider unbelted boaters in cold water to be engaged in grossly negligent behavior.
Immersion suits (also called survival suits or gumby suits) provide thermal protection during cold water immersion. These one-piece suits cover the entire body except hands and face, maintaining core body temperature during extended water immersion.
Immersion suits cost $300-$1,000 but can extend survival time from minutes to hours. Commercial fishermen and professional mariners wear immersion suits as standard practice in cold water season. Serious recreational boaters operating in winter conditions should consider them essential equipment.
Wetsuits and drysuits provide alternative cold water protection with varying levels of effectiveness. Drysuits, more effective than wetsuits, keep you completely dry and are particularly popular in cold water regions.
Additional flotation beyond standard PFDs:
– Type IV throw rings or life buoys with enhanced flotation capacity
– Rescue lines and drogues to stabilize capsized vessels
– Additional emergency flotation reserves
Communication and rescue equipment:
– VHF radio with emergency frequencies
– Backup communication (cell phone in waterproof case)
– Emergency position indicating radio beacon (EPIRB) for offshore vessels
– Visual distress signals (flares, mirrors)
Rescue and recovery equipment:
– First aid kits specifically equipped for cold water injuries
– Warming blankets and hand warmers
– Tools to assist overboard person recovery
Hypothermia develops when core body temperature drops below 95°F. Symptoms progress through stages:
Early signs (mild hypothermia):
– Shivering
– Difficulty speaking clearly
– Confusion or memory loss
– Loss of fine motor skills
Progressive signs (moderate hypothermia):
– Shivering decreases or stops
– Drowsiness or confusion increases
– Difficulty moving
– Loss of consciousness possible
Severe hypothermia:
– Apparent death (no pulse, not breathing)
– Extreme difficulty determining if person is alive
– Rescuers must treat all severely hypothermic persons as salvageable
Cold water rescue and rewarming:
– Remove wet clothing and place in dry wrapping
– Provide warm (not hot) beverages if conscious
– Warm core body temperature gradually
– Avoid rapid external warming which can cause “afterdrop”
– Seek immediate medical attention for moderate to severe cases
The saying “nobody is dead until they’re warm and dead” reflects the survival potential of hypothermia victims. Even apparent fatal cases respond to proper rewarming techniques.
HELP position (Heat Escape Lessening Posture): If in water without vessel, assume fetal position with arms crossed and legs together to conserve core heat.
Huddle position: Multiple people in water should huddle together to share body heat and maintain visibility.
Stay with vessel: Remain with your overturned or sinking vessel when possible. It’s larger and more visible to rescuers than a person, and provides some flotation.
Prevent exhaustion: Cold water hampers swimming. Minimize movement to conserve energy and body heat.
Wear appropriate clothing: Layered clothing, even when wet, provides more insulation than light clothing or none at all.
Maintain communications: Immediately contact authorities or other boaters when emergency occurs. Modern VHF radios can automatically transmit position data.
Most critically: Wear a properly fitted and fastened PFD at all times during cold water season. A PFD might be your only protection against becoming incapacitated in cold water before rescue arrives.
