As we eagerly anticipate the warmth of the sun and the thrill of setting sail once again, now is the perfect time to prepare your yacht for the upcoming season. Whether your vessel has been in winter storage or resting dockside for a few months, a little preparation ensures smooth and trouble-free cruising.

To help you prepare, I’ve compiled a comprehensive 10-point checklist covering all the essentials. Taking the time to go through each of these steps will not only extend the life of your yacht but also give you peace of mind for the adventures ahead.

1. Inspect the Hull & Bottom

Your yacht’s hull is its foundation, so start with a thorough inspection. Look for any cracks, blisters, or signs of damage. Pay close attention to the condition of the gel coat or paint and any stress cracks around high-load areas like chainplates and through-hull fittings. If necessary, apply a fresh coat of anti-fouling paint to prevent marine growth and keep the hull in optimal condition. This is especially critical for those in saltwater environments.

While at it, inspect the deck and topsides for leaks, particularly around chainplates, deck fittings, and hatches. A proactive check now can prevent costly repairs later.

2. Check the Propeller and Shaft

Your propulsion system needs to be in top shape for efficient sailing. Inspect your propeller for dings, pitting, or bent blades, which can cause vibrations and reduce performance. If you have a folding or feathering prop, lubricate its moving parts for smooth operation.

Examine the propeller shaft for signs of corrosion or excessive wear. Don’t forget to check the cutlass bearing—excessive play in the shaft can indicate it’s time for a replacement. Consider applying a protective coating like Petit’s Prop Coat Barnacle Barrier to protect your propeller in saltwater.

3. Change the Oil and Fluids

Oil changes are essential for prolonging the life of your engine. Even if your boat has been idle, oil can break down and become acidic. Change the engine oil, oil filter, transmission fluid, and coolant, and inspect the hoses, clamps, and belts for signs of wear.

Review your owner's manual for recommended maintenance intervals for marine diesel engines. A 1,000-hour service typically includes injector adjustments, aftercooler servicing, and heat exchanger flushing. Keeping a maintenance log is invaluable for personal reference and when it comes time to sell your yacht.

4. Inspect the Battery

A dead battery can quickly ruin a perfect day on the water. Test the voltage and check for corrosion on terminals. Clean and tighten all connections, and top off electrolyte levels in flooded lead-acid batteries.

For AGM batteries, a cold cranking amp test is performed to gauge overall health. Marine batteries typically last between three and six years, so if yours is aging, consider replacing it now to avoid unexpected failures mid-season.

5. Test All Electrical Systems

A properly functioning electrical system is critical for navigation and onboard comfort. Test all electronics, including:

• Navigation Lights
• VHF Radio (Perform a test call)
• Autopilot (Check the mounting brackets and operation)
• Pumps (Bilge, freshwater, macerator, etc.)
• Radar
• Chartploter
• Depth Sounder 

Catching electrical issues early will save you time and frustration once you’re out on the water.

6. Examine the Rigging (For Sailboats)

Sailors, take extra time to inspect your standing and running rigging. Look for frayed lines, cracked swages, and signs of corrosion. Check the mast, boom, and spreaders for any damage, and ensure the mast boot and deck seals are intact to prevent leaks.

It’s also a great time to drop your sails off at a local sail loft for inspection and minor repairs. A little preventative maintenance now can add years to the life of your sails.

7. Examine the Fuel System

Water contamination in fuel tanks can cause major engine issues. Inspect your fuel lines, Racor filters, and fuel tanks for any leaks or wear. Replace old fuel filters and consider adding a diesel additive to help clean injectors and prevent microbial growth.

If your boat has been sitting for a while, draining and replacing old fuel may be a wise precaution.

8. Clean and Test the Bilge Pumps

A properly working bilge pump is your first line of defense against unwanted water ingress. Inspect the float switch, test the pump, and clean out any debris or oil residue in the bilge.

Maintaining a dry bilge is also beneficial for fiberglass longevity, as fiberglass can absorb up to 15% of its weight in water, potentially leading to long-term damage.

9. Prepare Safety Gear

Safety should always be a priority. Check the expiration dates and condition of:

• Flares and Signal Devices
• Life Jackets and Harnesses
• CO2 Cartridges for inflatable PDFs
• Fire Extinguishers
• First Aid Kit
• Emergency Toolkit
• Spare Parts
• Life Raft (Ensure the certification is up to date)
• Ditch Bag (Including an EPIRB, emergency food/water, and handheld VHF) 

Being prepared ensures you and your crew can handle any unexpected situation.

10. Wash and Detail the Interior

Finally, make your time aboard even more enjoyable by giving the interior a deep clean. Wash upholstery, sanitize water systems, and check all onboard appliances to ensure they’re in working order.

Schedule professional detailing if needed, and stock up on essentials like toiletries, galley supplies, and fresh linens. A clean and organized yacht makes for a stress-free sailing season!
