Why is regular maintenance crucial on Swiss lakes?
The particular conditions of Swiss lakes - fresh water, wide variations in climate between summer and winter, and strict regulations - make boat maintenance particularly important. A well-maintained boat is not only safer and more pleasant to use, it also retains its value better over time. This guide takes you through the essential stages of seasonal maintenance and informs you about the most common repairs for your boat in Switzerland.
Seasonal maintenance: the responsible owner's calendar
Spring preparation (April-May)
Getting your boat back in the water after wintering is a crucial moment that requires special attention:
Hull and deck inspection
Checking for signs of osmosis in polyester hulls
Checking and repairing any cracks
Application of antifouling adapted to the fresh waters of Swiss lakes (average cost: CHF 80-150/litre)
Engine overhaul
Changing oil and filters
Checking sacrificial anodes (particularly important in freshwater)
Testing cooling systems
Checking belts and hoses
Electrical systems
Battery test and reinstallation
Checking the electrical panel
Checking navigation lights (compulsory under Swiss regulations)
Expert advice : "In Switzerland, antifouling for freshwater is different from that used at sea. Opt for specific products that are more respectful of the environment and adapted to our lakes." - Marc Dupont, Chantier Naval du Léman
Summer maintenance (June-September)
During the sailing season, regular vigilance is essential:
Weekly checks
Engine oil level
Condition of ropes and mooring lines
Operation of bilge pumps
Monthly maintenance
Thorough cleaning of the hull (without aggressive products, in compliance with Swiss environmental regulations)
Inspection of propeller and rudder
Checking safety systems (waistcoats, fire extinguishers, fuses)
Preparing for winter (October-November)
Wintering is a crucial stage in the Swiss climate:
Engine and mechanical systems
Complete oil change (oil, coolant)
Specific frost protection (average cost: CHF 50-100)
Cylinder misting for petrol engines
Fresh water system and tanks
Complete drain to prevent freezing
Disinfection of drinking water tanks
Protection of pumps and valves

Adequate ventilation to prevent condensation
Routine repairs: anticipating for better management
Engine problems: diagnostics and solutions
Good to know: Hourly rates for marine engineers in Switzerland vary between CHF 120 and 180, depending on the region. Lake Geneva and Lake Zurich generally have the highest rates.
Work on hull and deck
Electrical and electronic systems
Electrical problems account for a large proportion of interventions on boats in Switzerland:
Electrical panel complete overhaul (CHF 800-1500)

Questions to ask before entrusting your boat
Is the yard certified for your type of boat?
Do they offer a detailed written quote?
What guarantee do they offer on the work?
Can they provide customer references?
Are they approved by the major brands (important for boats under warranty)?
Do-it-yourself maintenance: what you can do and what you should delegate
Work that can be carried out by the owner
Some maintenance tasks can be carried out by the owner:
Regular cleaning of the hull and deck
Waxing and polishing (products adapted to Swiss lakes)
Routine checks (levels, filters, etc.)
Teak care with specific products
What's best left to the professionals
Other operations require the expertise of a professional:
Complex engine work
Structural repairs to the hull
Work on the electrical system
Antifouling applications (to comply with environmental standards)
Annual maintenance costs: budgeting intelligently
For a medium-sized boat (8-10m) on a Swiss lake, you will need :
Budget tip: "Plan on spending around 3-5% of your boat's value on annual maintenance. This simple rule helps you anticipate costs and avoid unpleasant surprises." - Swiss Boat Owners' Association
Regular maintenance, a profitable investment
Meticulous maintenance of your boat is not only a question of safety and sailing pleasure, it's also a wise investment. In the Swiss context, where well-maintained boats retain a high value on the second-hand market, every franc invested in maintenance can translate into a higher resale value.
By following this maintenance schedule, choosing the right service providers and budgeting intelligently, you can significantly extend the life of your boat while maximising your enjoyment of the magnificent Swiss lakes.
