Your yacht. Always watched over.
Harbor Guardian is yacht management software built for professional yacht managers and management companies. It creates a living record of vessel condition — what was inspected, what changed, what needs attention, what work was completed, and what still comes next.
Boats rarely fail all at once. They change a little at a time.
Every yacht is continuously exposed to time, heat, vibration, moisture, salt, movement and use. Small changes accumulate long before they become obvious equipment failures, maintenance problems or interruptions to vessel readiness.
A stain spreads slightly. A fitting begins to discolor. A battery takes longer to recover. A hose looks different than it did during the last inspection.
Weeks pass. Inspections happen. Preventive maintenance gets performed. Work gets discussed. Context becomes scattered across people, photos, texts, invoices and memory.
Eventually the small change becomes a finding, a repair, an operational interruption — or a failure that now feels sudden even though the evidence developed over time.
Harbor Guardian preserves vessel condition over time so small changes remain visible, inspection history stays connected, and the next maintenance decision does not depend on somebody remembering what happened months ago.
From observation to certainty.
Harbor Guardian connects yacht inspections, vessel condition findings, preventive maintenance, work orders, projects, vendors and completed service history into one traceable operating system. What begins as an observation stays connected through review, action and verification.
Capture vessel condition
Perform structured yacht inspections, document systems and spaces, capture photos, record observations and preserve visual evidence for future comparison.
Notice what changed
Compare current vessel condition with prior inspections and surface deterioration, anomalies, recurring issues and changes that deserve professional attention.
Determine what matters
Review observations and AI-assisted changes, create findings, establish priorities and decide whether maintenance, monitoring or immediate action is appropriate.
Coordinate the work
Turn findings into tasks, preventive maintenance, work orders or larger yacht projects while keeping vendors, documentation and history connected.
Close the loop
Confirm work was completed, preserve before-and-after evidence, maintain service history and carry the vessel's operational story into the next inspection.
Visual difference identified near the mounting surface. Flagged for professional review — not automatically accepted as a finding.
AI that looks for change. Professionals decide what it means.
AI Surveyor compares structured inspection images of the same yacht systems, equipment and spaces over time. It helps surface visual differences such as corrosion, leaks, damage, wear, movement, discoloration and other condition changes that may be difficult to recognize across weeks or months.
Harbor Guardian does not replace the judgment of a yacht manager, captain, technician or surveyor. It preserves visual history and helps experienced professionals know where to look more closely.
Everything around the yacht. Connected.
Harbor Guardian is not another yacht maintenance checklist. It creates a persistent operational record of the vessel — its systems, equipment, inspections, findings, preventive maintenance, service work, documents, vendors and condition over time.
Instead of information being fragmented across spreadsheets, text messages, photo libraries and individual memories, the history stays connected to the yacht and the people responsible for managing it.
Vessels & Components
Build a structured vessel registry covering onboard systems, equipment and components so inspections, maintenance and history have the right context.
Inspections & Images
Perform recurring yacht inspections and preserve a chronological photographic record of vessel condition for comparison and accountability.
Findings
Turn inspection observations and condition changes into reviewed findings with priorities, evidence, ownership and a clear history of what happened next.
Tasks, Work Orders & Projects
Manage preventive maintenance, repairs, service work and larger yacht projects without separating execution from the condition that caused the work.
Documents & Manuals
Keep manuals, service records, invoices, reports and supporting documents organized around the vessel and available when decisions need to be made.
Vendors & Inventory
Track who serviced the yacht, what work they performed, what parts and supplies are aboard, and how that activity fits into the vessel's operating history.
Built around the responsibility of caring for the vessel.
Harbor Guardian is designed for yacht management companies, professional captains, fleet managers and owner representatives responsible for maintaining vessel readiness, coordinating maintenance and service, preserving condition history and communicating clearly with yacht owners.
Routine vessel oversight
Manage recurring inspections, preventive maintenance, vessel readiness and condition monitoring without allowing small details to disappear between visits.
Projects & service coordination
Connect findings with repairs, vendors, work orders, estimates, projects and completion evidence so the reason for the work stays attached to the work itself.
Absentee owner management
Give owners confidence that somebody understands the yacht, knows what is happening aboard, and can show what has been inspected, addressed and completed.
Owners should never have to wonder what is happening with their yacht.
Harbor Guardian gives yacht owners clear visibility into vessel condition, inspection history, open findings, preventive maintenance, current work and completed service — without forcing them into the operational details required to manage the yacht day to day.
For absentee and seasonal owners especially, that creates something more valuable than another maintenance report: a defensible record showing what was observed, what required attention, what was done and what remains outstanding.
The yacht is always changing. Your understanding of it should never fall behind.
Professional yacht management begins with knowing the vessel — its condition, its history, what needs attention and whether the work was actually completed. Harbor Guardian helps preserve that understanding over time.
A better way to understand what is happening aboard.
Whether you manage multiple yachts, captain one vessel, or simply want a clearer view of your own yacht, Harbor Guardian keeps condition history, open items, maintenance, and completed work connected in one place.
