As spring brings another exciting boating season, now is the time for boat owner’s seasonal checks. After storage, commissioning checks are an essential safety feature, and ensure your boat operates reliably for the season ahead. Below are key checks to complete, no matter where you are storing your boat, be it a marina, on a trailer, or at a boat yard.
Check your Hull and Fittings.
Begin your checks by examining the hull and looking for signs that damage or cracks have appeared and/or osmotic blistering has occurred over the winter. This is particularly important for the lower regions of the hull, where winter stressors may cause damage to the hull and other issues for your boat. Inspect all your skin fittings and through-hull valves, and seacocks, and turn each seacock multiple times to confirm free movement and a proper seal. Leaks can quickly become your biggest problem when you’re far from shore, so never skip this important maintenance.
Check your Engine and Fuel System.
Prior to starting your engine for the season, your engine requires a number of checks. First, check the engine oil and replace oil that is dark or has debris mixed in it. Inspect your fuel filters and fuel lines for signs of damage and deterioration. If your boat has been sitting for several months, draining old fuel and replacing with new, or using fuel stabilizer to keep existing fuel fresh is advisable. When you are ready to start your engine, prime the fuel system. Also check your cooling system to ensure your engine’s cooling system is protected from freezing temperatures and stays intact.
Check your Electrical Systems and Batteries
After sitting for the season, boat batteries are depleted and may have sustained damage. Prior to the start of the boating season, confirm the voltage of each battery and resolve any cell imbalance by adding the appropriate cell in each battery.
Check battery terminals for corrosion and clean with a protective coating. Test battery voltage and consider replacing batteries that show signs of wear. Check all electrical wiring and check for chafing. Check for corrosion and damage caused by rodents. Test the navigation lights, cabin lights, and all electrical equipment. Don’t forget to check the connections and the shore power and make sure all outlets and sockets work.
Safety Equipment and Lines
Review your safety equipment and replace as necessary. Life jackets will tend to lose buoyancy over the years. Fire extinguishers should be checked for pressure. Your life raft (if you have one) should also be checked according to the manufacturer’s instructions. Check all rigging, ropes, and lines for UV damage, or those that are frayed or weak. Pay attention to the heavily stressed lines.
Plumbing and Fresh Water Systems
If you have a fresh water system on your boat, that you have drained for the winter, you should flush the system before using it. Any hoses or connections that are stiff or cracked should be replaced. Test your pumps, especially the galley and the heads, to make sure they are working. Any antifreeze that was used in the system during the winter should be flushed out with fresh water. Poor water quality in the spring is likely due to insufficient system flushing.
Structural and Cosmetic Checks
Look for water stains, mould, or mildew that grew over the winter.
Check for moisture and musty odors inside lockers and cabinets. Inspect trim and joinery for swelling and warping, as well as rot. Check hatches, portholes, and cabin windows for proper sealing and function. Ensure all ventilation systems are clear and functioning to prevent moisture buildup during the boating season.
Test Everything Before Departure
Run your boat systems after completing all inspection and maintenance tasks. Start the engine and let it warm up. Check for sounds or vibrations that are not normal. Run the water systems and confirm the drains work appropriately. Test navigation equipment, radio, and safety systems. If possible, take a short test cruise in calm conditions to assess how your boat responds to different surface conditions before heading out.
Professional Help When Needed
If you are uncertain about any aspect of commissioning your boat, do not be afraid to contact professionals. Many boat centers and marinas offer commissioning services to help identify problems you may not see. An engineer can perform diagnostics on the engine. specialised teams can work on complex systems. Investing in this service avoids problems later in the safe boating season.
Spring boating season preparation takes some time, but it ensures your peace of mind when you go boating. A methodical approach to these checks will ensure you start the season with a boat that is safe and well-maintained.
