Yacht Sea Trial and Delivery Readiness: What to Check Before Commitment

Prepare before leaving the berth

Review known defects, recent repair work, fluid levels, alarms, charging systems, navigation equipment and any systems specifically affected by the work being tested. Agree in advance what readings or behaviour need to be observed so that the trial has a clear purpose.

• Main-engine and gearbox operation
• Generator performance under representative load
• Cooling temperatures and seawater flow
• Steering, thrusters and hydraulic systems
• Electrical charging and distribution behaviour
• Navigation and operational systems relevant to the passage
• Leaks, alarms, vibration and abnormal noise

Test repaired systems under the conditions that matter

A repair that appears satisfactory alongside may behave differently once engines are loaded, the generator carries hotel demand or hydraulic equipment is operated repeatedly. Trial conditions should therefore reflect the original complaint wherever this can be done safely.

Close-out matters as much as the trial

The final record should state what was tested, what passed, what remains outstanding and any limitations that still need attention. For a delivery or handover, documentation, spare parts, manuals and known defects should be considered alongside machinery condition.

How ACG can assist

ACG can prepare readiness checks, attend trials where required, record observations and maintain an outstanding-items list for follow-up. Specialist commissioning or manufacturer-required testing is carried out by the relevant qualified party.
