Plans / Tests and trials:

The following trials are carried out before delivery of the yacht:
Engine tests
Engine trials at sea check that the following are in perfect working order:
• Engine
• Hot and cold start
• Oil pressure
• Fuel flow
• Fuel and cooling systems
• Exhaust gas pressure
• Soundproofing
• Vibrations
Electrical panel and system tests
The electric circuits are tested separately to check load and heat dissipation.
Refrigeration system tests
The refrigerator compressor is tested to check for any freon leaks.
The refrigerator compartment is cooled and kept at a low temperature for a sufficient time to test it.
Utilities and hydraulic circuits tests
The following utilities and circuits are tested: Bilge pumps
Pipes from the galley gas cylinder
Fresh water pump
Winches and deck gear tests
The winches and deck gear are load tested to check they function correctly.
The correct operation and sensitivity of the steering is tested at all speeds and in manoeuvres in both forward and reverse.
