A. When cleaning a vessel, use regular household detergents and cleaners.
B. When storing a vessel for a long time, it is best to keep it in the sun and uncovered.
C. When replacing electrical parts on a vessel, never use automotive parts.
D. When preparing your vessel for cold weather, use antifreeze that contains ethylene glycol.
✅ C. When replacing electrical parts on a vessel, never use automotive parts.
Explanation:
Option A (Incorrect): Household detergents contain chemicals like ammonia, sodium hypochlorite, or petroleum distillates, which harm marine life. The Environmental Protection Agency (EPA) and BoatUS recommend using biodegradable, phosphate-free marine cleaners to protect water ecosystems (BoatUS, 2024).
Option B (Incorrect): Storing a boat uncovered exposes it to UV damage, water accumulation, and material degradation. According to the National Marine Manufacturers Association (NMMA), boats should be stored in a covered, ventilated space to prevent deterioration (NMMA, 2023).
Option C (Correct): Marine electrical systems operate in high-moisture, salt-prone environments, making automotive parts unsuitable. The American Boat & Yacht Council (ABYC) mandates the use of marine-grade wiring and components to prevent corrosion and electrical hazards (ABYC Standards, 2024).
Option D (Incorrect): Ethylene glycol antifreeze is used in marine winterization but must be properly diluted to ensure engine protection and environmental safety. Propylene glycol antifreeze is recommended as a less toxic alternative for marine applications (BoatUS, 2023).
