As the winter chill sets in, boat enthusiasts need to ensure their electric yachts are properly cared for to guarantee optimal performance and longevity. Winterizing an electric yacht involves a set of considerations similar to those for electric cars, with a few additional aspects specific to maritime environments.
Battery Maintenance:
Just like in electric cars, the battery is the heart of an electric yacht. In modern yachts, two types of batteries can be found: traditional lead-acid ones, similar to car starter batteries, and moder lithium-ion ones, like in electric cars.
Lead acid batteries which you may have installed for hotel loads or generator starters shall be recharged, and disconnected from any loads. Before storing your yacht for the winter, fully charge the battery. Consider investing in a quality battery maintainer to keep it at an optimal charge level throughout the colder months.
Modern lithium-ion batteries shall be stored in conditions defined by battery manufacturer. Depending on battery model it might be between 30 and 50% of SOC. In general, lithium ion batteries degrades quickie if are left fully charged, so read your owner manual carefully, or consult your local dealer.
Propulsion System Check:
Inspect the propulsion system, including propellers and shafts, for wear or damage. Lubricate moving parts to prevent corrosion during winter and consider removing propellers for secure, dry storage. For optimal electric motor care, store the yacht indoors with temperatures above -20 ºC and humidity below 60%.
Treat exposed surfaces against corrosion, seal cable exit holes, and periodically rotate the shaft by hand to prevent grease migration. These measures ensure the propulsion system stays in top condition during winter and extended storage.
Hull Maintenance & Interior Care:
Choose a suitable storage location that protects the yacht from the elements. If possible, store it indoors to shield it from harsh winter weather. If indoor storage isn't available, invest in a durable, weather-resistant boat cover to safeguard against snow, ice, and freezing rain.
Conduct a thorough inspection of the hull for any signs of damage, such as cracks or blistering. Clean and wax the hull to create a protective barrier against ice and debris. Consider applying an anti-fouling coating to discourage the growth of marine organisms during storage.
Just as you winterize the exterior, the interior of the yacht also requires attention. Remove any perishable items, clean the cabin thoroughly, and ensure all electronic components are turned off to conserve battery power. Consider using moisture absorbers to prevent mold and mildew growth.
Winterizing the Plumbing System:
Ensure all water systems on board are properly winterized to prevent freezing. Drain the water tanks, pump, and pipes to avoid damage from ice formation. If applicable, add non-toxic antifreeze to the plumbing system to further protect against freezing temperatures.
Regular Inspection:
Throughout the winter, periodically check on your yacht. Remove accumulated snow from the cover, inspect the mooring lines, and ensure that the storage location remains secure. These routine checks will help you catch any potential issues early on.
Winterizing your electric yacht is a crucial step in ensuring its longevity and optimal performance. By taking the time to properly store and maintain your yacht during the winter months, you'll be ready to hit the water with confidence when the warmer weather returns. Following these tips will help you preserve your investment and enjoy many more seasons of smooth sailing.
