Modern superyacht underway at sea.

Superyachts & Yacht Management

Superyacht maintenance and yacht management software.

Simpler technical management. Clearer oversight.

Keep maintenance, records, inventory and vessel information organised, with clearer oversight for captains, engineers and management teams.

The whole yacht, working together.

Maintenance, defects, tasks, inventories and records in one connected platform. Each department gets the tools for its own work.

Start with the departments you need, then expand.

Whole-Vessel Operations

One platform for every department.

Management

  • Maintenance, defects, projects and compliance across one yacht or a managed fleet
  • Compare yachts without collecting reports by email
  • A record that survives a change of captain or crew

Engineering

  • Planned and running-hour maintenance schedules
  • Defects tracked through to close-out, with history intact
  • Technical records, manuals and critical spares held against the machinery

Deck

  • Tender, toy and deck equipment servicing on schedule
  • Safety and equipment checks recorded as they are done
  • Watch and operational logs in one place

Interior

  • Turnaround and pre-charter checklists
  • Inventories and consumables without a parallel spreadsheet
  • Standing procedures available to whoever is aboard

Galley

  • Provisioning and stock levels recorded against the trip
  • Equipment servicing and temperature checks on a schedule
  • Dietary, allergen and preference notes kept with provisioning records

Machinery Condition

Predictive maintenance for superyachts

Machinery condition monitoring brings the yacht's readings, running hours and maintenance history into one view. Engineers can see a condition changing while there is still time to look into it between trips.

  • See it earlier

    Drifting temperatures, vibration and consumption show up as trends before they become faults.

  • Plan the work

    Investigate and schedule maintenance around the yacht's programme, not in the middle of it.

  • Clearer oversight

    Captains and management see machinery health and outstanding work without asking for a report.

Indications for an engineer to investigate, not decisions made for them.

How predictive maintenance works

Fuel and Energy

Make better use of fuel and energy.

See fuel and energy use alongside how the yacht is being run, and identify where it could be used better.

Implementation & Ongoing Support

A working partnership, not just software.

We work alongside your team to understand the operational problems, configure Mariners Log around real workflows, and provide ongoing support as your needs evolve.

01

Tailored demo

Built around your vessels, current systems and priorities.

02

3-month paid pilot

An agreed pilot in real operation, with guided setup and training.

03

Annual subscription

Continue on an annual subscription once the pilot has proved its fit.

What the subscription includes.

Standard onboarding, training and ongoing support. The 3-month pilot is priced separately and agreed upfront.

Alongside what you already use.

Works alongside your existing systems. Bespoke integration or custom work is scoped and agreed upfront.
