How to Prepare Your NZ Boat for Winter

With New Zealand's winters just around the corner, it's crucial to prepare your boat for storage. Proper care during the off-season can prevent damage, ensure a smooth transition back to the water and save you money in the long run. This comprehensive guide will walk you through everything you need to know to protect your vessel from the elements and keep it in top condition.

Preparation

• Gather Supplies: Before you begin, gather the necessary tools and materials. This includes cleaning products, waxes, polishes, antifreeze (if applicable), fuel stabilizer, dehumidifier and basic tools.

• Timing: Aim to winterize your boat in autumn before the harshest conditions arrive. This allows you to complete the process thoroughly and avoid potential damage.

Cleaning Your Boat Before Winter

• Wash and Wax: Give your boat a thorough cleaning with a high-quality marine cleanser. Remove built-up grime, salt, and stains that can cause corrosion over winter. Apply a coat of marine wax to protect the gelcoat or painted surfaces from the elements and UV damage.

• Remove rust and pitting: If rust has pitted and gone beyond surface rust, you may need to get it welded and then pre-passivated with an acid solution. This should be done by a professional and followed up with a marine-grade polish. Mount Marine Engineering offers comprehensive stainless steel rust removal services. Learn more about how you can keep your boats stainless steel shining bright at our blog here.

• Interior Sprucing: Don't neglect the inside! Clean and remove any accumulated water from the bilge. Inspect and lubricate all seacocks for smooth operation. Clean and dry the cabin thoroughly, including compartments, upholstery and cushions. Consider storing cushions, soft furnishings and fabrics indoors over winter to prevent mildew growth.

Protecting Your Boat Cover in Winter

• Inspect and Clean: Regularly check your boat's canvas covers for tears, leaks or signs of wear. Clean them thoroughly to remove dirt, salt and mildew. If necessary, reapply a waterproofing treatment to protect the canvas from the elements.

• Proper Storage: Ensure the covers are completely dry before storing them indoors. Mold and mildew can grow on damp canvas.

• Invest in a High-Quality Cover: A well-fitted, durable boat cover is essential for protecting your vessel during storage. Mount Marine Engineering in Tauranga offers a wide range of boat covers tailored to different boat sizes, shapes and types.

Engine and Fuel System

• Outboard Motors: Follow the manufacturer's recommended winterization procedure. This typically involves fogging the engine to protect internal components, changing the oil and filter to remove contaminants then

   adding fuel stabilizer with a fresh tank of fuel to prevent corrosion and fuel system issues.

• Inboard Engines: For inboard engines, the process can be more complex and may be best left to a qualified mechanic. However, you can still prepare by adding fuel stabilizer and addressing the cooling system with antifreeze (refer to your manual for specific instructions).

Boat Battery Care

• Disconnect and Store: Disconnect the batteries to prevent them from draining over winter. Clean the terminals and store the batteries in a cool, dry place.

• Battery Replacement: If your batteries are nearing the end of their lifespan, consider replacing them before winter storage. Mount Marine Engineering offers a wide range of high-quality marine batteries and battery chargers available for purchase online.

Choosing the Right Storage Location

• Land Storage: Storing your boat on land provides the most protection from the elements. However, it requires additional effort to transport and secure the vessel.
• In-Water Storage: While convenient, in-water storage can expose your boat to marine growth and other potential damage. If you choose this option, ensure the marina offers winterization services and has adequate security measures.

Additional Considerations for In-Water Storage

• Hull Cleaning: Regular hull cleaning is essential to prevent marine growth that can affect your boat's performance and fuel efficiency.

• Antifouling Paint: Applying antifouling paint can help deter marine growth, but it needs to be reapplied periodically. Consult a marine professional for recommendations on the best type of paint for your boat and local conditions.

Addressing Moisture During Storage:

• Ventilation: If storing your boat on land, ensure proper ventilation to prevent condensation and mold growth. Prop open hatches and consider using dehumidifiers to absorb excess moisture, especially in humid climates.
• Consider Purchasing a Boat Cover Vent: The Oceansouth Boat Cover Vent is a valuable tool for maintaining a dry and healthy environment inside your boat cover. It prevents harmful moisture and humidity buildup, protecting your vessel from:
  • Mildew and mold growth: Excess moisture trapped under a cover creates the perfect environment for these unwanted guests. The vent allows for constant air circulation, keeping your boat dry and healthy.
  • Material damage: Moisture can weaken and damage your boat cover or other materials over time. Proper ventilation extends the lifespan of your covers and keeps your boat looking its best.

Spring Boat Preparation

• Rods & Reels: Service your fishing rods and reels by cleaning and lubricating them to ensure they're in top shape for the upcoming season.

• Fenders & Lines: Inspect and clean fenders and dock lines. Store them properly to prevent cracking or rotting over winter.

• Rod Racks & Holders: Keep your fishing rods organized and protected with our high-quality rod racks and holders. Mount Marine Engineering offers a wide selection to suit your specific needs, whether you have a few rods or a large collection.

Don't Forget:

• Label Everything: Clearly label any disconnected hoses, drained fluids,

  or removed parts for easy reassembly in spring. This will save you time and frustration when the boating season kicks off again.

• Schedule Spring Service: Consider booking your boat in for a professional service before hitting the water again. This ensures everything is in top condition for the new season, giving you peace of mind on your first spring outing.

• Follow manufacturer's recommendations for specific boat models and engines.

• Consult a marine professional for advice on local conditions and specialized tasks.

• Winterize your boat early (Autumn) to avoid rushed work and potential damage.

• Invest in quality boat covers and marine accessories for added protection.

• Take advantage of our stainless steel rust corrosion removal and metal polishing services to ensure your boat looks its best.

• Enjoy peace of mind knowing your boat is well-prepared for the winter season.

By following these steps, you can ensure your boat is well-protected during the winter and ready for a smooth transition back to the water in the spring.
