Spring and early summer bring excitement to boaters across the Duluth-Superior area, but one hidden danger remains—cold water. While the sun may be shining and air temperatures feel warm, Lake Superior’s water often hovers around 50°F this time of year, and those chilly depths pose serious risks to even experienced boaters.
The Duluth Sail & Power Squadron (DSPS) wants to ensure that every boater understands the dangers of cold water immersion and how to prepare for safe outings during the early season.
Understanding the Risk: Cold Water Shock & Hypothermia
Cold water can shock the body instantly. Within seconds of falling into 50°F water, the body can experience:
- Cold Water Shock: An involuntary gasp followed by rapid breathing, which can lead to water inhalation.
- Muscle Incapacitation: After just 10–15 minutes, limbs may lose coordination, making self-rescue difficult.
- Hypothermia: Prolonged exposure can cause confusion, unconsciousness, and even death.
Dress for the Water, Not the Weather
Even on sunny days, boaters must prepare for the reality of cold water:
- ✅ Wear a life jacket at all times
- ✅ Consider wearing cold water gear like a wetsuit or dry suit if paddling or sailing solo
- ✅ Dress in layers with moisture-wicking materials
💡 DSPS Tip: Keep a dry bag with extra clothes, a towel, and an emergency blanket on board.
Prevention Starts with Smart Planning
Avoid emergencies by preparing for the unexpected:
- 🛟 File a float plan with someone on land before heading out
- 📱 Bring a fully charged phone or VHF radio in a waterproof case
- ⚠ Stay clear of rough waters and weather changes
- 📍 Know your launch location, shoreline access points, and nearby marinas
