1. Schedule Regular Inspections
- Yacht batteries should be visually checked for corrosion, swelling, or cracks. Voltage testing ensures each unit is holding charge properly.
- Technician tip: Record inspection results in your yacht’s maintenance log to track performance over time.
- Salt and moisture accelerate corrosion, which interrupts power delivery. Cleaning terminals with a proper solution and applying anti-corrosion grease is key.
- Technician tip: Avoid makeshift cleaners—use marine-grade products for longer protection.
- For wet-cell batteries, low electrolyte levels reduce capacity and increase overheating risks. Always top up with distilled water only.
- Technician tip: Never overfill—keep levels just above the plates.
- An alternator or charger working incorrectly can overcharge (causing swelling) or undercharge (leading to dead batteries). Regular testing prevents this.
- Technician tip: Match your charging system to your battery type—AGM, Gel, or Lithium each require different settings.
- Simulating real power demands reveals weak batteries before they fail at sea. Yacht technicians often include load testing during seasonal service.
- Technician tip: Always test under realistic onboard conditions—not just idle charging.
- In yachts with multiple batteries, imbalance leads to uneven wear. Replacing a weak unit promptly prevents damage to the entire bank.
- Technician tip: Never mix old and new batteries—install replacements in matched sets.
- Even with excellent care, batteries have a lifespan. Proactive replacement ensures reliability during long cruises in the Adriatic.
- Technician tip: Upgrade to lithium for faster charging, lighter weight, and longer cycle life.
- Corroded terminals – solved with cleaning and protective grease.
- Dead batteries – avoided through inspections and proper charging.
- Imbalanced battery banks – corrected with replacements and balancing.
- Low electrolyte levels – maintained with careful monitoring.
- Faulty charging systems – fixed with diagnostic checks and repairs.

A yacht’s fuel system is its lifeline. Without clean, high-quality fuel delivery, even the most advanced engines can suffer from poor performance, corrosion, or unexpected breakdowns. In Montenegro, where yachts cruise extensively across the Adriatic, preventive care is the best protection against costly repairs.
The bilge system is often called the “hidden heart” of a yacht. It quietly manages excess water, protects stability, and ensures safe navigation. Yet, it is also one of the most neglected areas on board. Over time, the bilge collects sludge, fuel residue, oil, and debris, leading to foul odors, system failures, and even environmental violations.
