Safety First:** You MUST have tip-over shutoff and low-oxygen shutoff. Never use a home heater without it on a boat.**2. Power:** Check your power. 1500W heaters trip 30A marina breakers. For battery or 30A, stay under 750W or go propane.**3. Ventilation:** Propane and diesel need fresh air. Crack a vent, use a CO detector.**4. Damp Air:** Cheap heaters rust in one season here. Look for marine grade or ceramic with sealed elements.**My Pick:** Mr. Buddy as your main portable + a Lasko MyHeat for quiet overnight when plugged in at the dock or park. That combo covers 90% of Island boaters and RVers.*IslandTested.ca is supported by readers. When you buy through our links, we may earn a small commission at no extra cost to you.
