Engineering Lobooks
Our Engineering Logbooks category features specialised logbooks designed for yacht engineers, ETOs, chief engineers, and technical crew working aboard yachts and superyachts. These professional logbooks provide structured formats for documenting engine data, fuel usage, generator loads, safety checks, machinery performance, maintenance schedules, and ISM/MARPOL compliance information.
Each engineering logbook follows industry-standard maritime templates, ensuring accurate technical reporting, audit-ready documentation, and continuity across engineering watchkeepers.
Explore engine room logs, running logs, technical maintenance logs, daily engine logs, and customisable logbooks tailored to your vessel’s operational needs.

Frequently Asked Questions
What is an engineering logbook used for on a yacht?
An engineering logbook records all technical and mechanical operations on a yacht, including engine readings, generator loads, fuel consumption, machinery performance, maintenance actions, alarms, and safety checks. It provides the vessel’s official technical record and supports safe, compliant operation.
What should be recorded in an engine room logbook?
Typical engine room logbook entries include:
Hourly engine and generator readings
Oil pressure and temperature
Fuel and water levels
Bilge and pump activity
Running hours
Mechanical observations or anomalies
Alarms and corrective actions
These logs are essential for preventive maintenance and technical audits.
Why are engineering logbooks required on yachts and superyachts?
Engineering logbooks are required to document machinery performance and compliance with ISM, SOLAS, and MARPOL requirements. They provide traceability during inspections, help diagnose mechanical issues, and protect the yacht in the event of insurance claims or disputes.
What is the difference between an engine daily log and an engine running logbook?
An engine daily log captures routine readings, daily checks, and overall system performance.
An engine running logbook documents live machinery operation during voyages, including continuous readings, loads, and performance trends.
Both are complementary tools for complete engineering documentation.
How long should engineering logbooks be kept onboard?
Most yachts retain engineering logbooks for at least five years, although ISM-managed vessels may store them longer. These logs provide vital documentation for refit planning, audits, flag-state inspections, and long-term maintenance tracking.
Where can I buy professional engineering logbooks for yachts?
Yacht crew can purchase professional engineering logbooks—including engine daily logs, running logs, technical maintenance books, and fuel logs—directly from YachtNeeds. These logbooks are built for marine environments and follow recognised technical reporting standards.
