Winterizing

Winterizing a boat means preparing it for the winter period so it stays protected while not in use. Even though Mallorca has mild winters, humidity and salt air can still cause corrosion, mold, and engine problems if a boat is left untreated. Proper boat maintenance helps keep the boat in top condition for the next season.

Winterizing contains:

• Engine care:
  Flush the engine with fresh water to remove salt. Add fuel stabilizer to prevent fuel breakdown. Change engine oil and filters to remove moisture. Lubricate moving parts to protect from corrosion.

• Cooling and water systems:
  Drain freshwater tanks, pipes and pumps to avoid bacteria and bad smells. Clean the toilet (head), shower and sinks thoroughly. Reducing moisture inside the boat helps prevent mildew.

• Battery and electrical systems:
  Disconnect batteries or keep them on a slow charger. Check electrical connections, as humidity can damage wiring and contacts over time.

• Interior protection:
  Clean and air the cabin. Remove cushions and fabrics or store them dry. Place moisture absorbers or a small dehumidifier inside to reduce mold risk.

• Hull and deck maintenance:
  Rinse the hull and deck to remove salt. Clean stainless steel fittings to prevent rust. If the boat is hauled out, consider applying anti-fouling to protect against marine growth.

• Shrink wrap protection:

  Boats are often wrapped in protective marine shrink wrap to shield them from humidity, dust, UV exposure, and winter storms. This wrapping helps keep the boat dry and well-ventilated while stored, especially for boats kept outdoors.

Winterizing helps extend the life of your boat, reduces repair costs, and ensures it is ready for a smooth start to the next boating season in Mallorca.
