…because every yacht needs
an operating system.
Chat groups and spreadsheets are not yacht infrastructure.
YOS replaces disconnected tools with 40+ native services — finance, maintenance, logbooks, safety, crew, compliance — on one platform that works at sea and syncs at port.
Built by a working captain.
For captains and crew.
Not for the desk office.
Full yacht management in your pocket — every module, every device, online or offline.

Digital Logbook
YOS isn't another system to maintain — it's your entire operation in your pocket, updated on the spot, not after a long day in front of a PC.
Runs Anywhere
Every module works at sea. No internet required. Changes sync automatically when you're back online. An operating system works whether connected or not.
Yacht Ironwall
Every yacht is a data fortress. Yacht-level isolation enforced on every table, every query — one crew can never see another yacht's finances, crew, or documents. Every access audited.
Reads Your Yacht
Live data from your sensor network — engines, tanks, batteries, generators, GPS, weather. Feeds logbook entries, drives maintenance by running hours, verifies MARPOL positions.
Thinks, But Asks
System-level intelligence reads documents, spots patterns, and handles admin work — but never acts without human command. Authority stays with the crew.

Where the data goes
The AI Captain runs across the entire operating system. It reads documents, spots patterns, and handles administrative work — but never acts without your command.
The AI handles data entry and pattern recognition. Humans make every decision. That's not a limitation — it's the design.
Photograph a receipt.
It becomes a categorized ledger entry, routed to the correct budget, waiting for the Captain's approval. No data entry. No reconciliation later.
A crew certificate is 45 days from expiry.
The system flags it at 90 days. Then 60. Then 30. Then 7. Port authority requirements are cross-referenced automatically. Nothing slips through.
Generator running hours approach service interval.
A maintenance task is proposed, parts availability checked against inventory, and the work order queued for Chief Engineer review — before you notice the gauge.
AI Captain — Active
Every decision remains with the crew.
Standard Procedures & Safety Management
Standardized SOPs and a living Safety Management System. Drills tracked, incidents reported, non-conformities resolved to closure. Audit-ready from day one.
Flag State Certificate Matrix
Every statutory certificate, manual, plan, and insurance policy — tracked across 10 major flag states with automated expiry alerts at 90, 60, 30, and 7 days.
STCW Matrix & Hours of Rest
Crew certificates mapped per rank per flag state. Hours of rest monitored. Endorsement tracking. Expiry alerts per crew member before every voyage.
Environmental Compliance
Digital Oil Record Book and Garbage Record Book. Multi-signature workflow. Entries locked permanently after sign-off. GPS-verified discharge positions.
From Receipt to Ledger
Photo a receipt. AI categorizes it. Approval workflow runs. Budget updates. Banking syncs. Audit trail complete. One photo, zero data entry.
From Sensor to Service
Running hours arrive from live telemetry. The PMS threshold is reached. A job is proposed, parts pulled from inventory, the work order completed, equipment history updated.
From Passage Plan to Voyage Record
Route planned with weather overlay. Captain signs digitally. Telemetry logs position. The deck log fills itself. At arrival: a complete, shareable voyage record.
Most yachts run 3–5 separate professional tools — one for maintenance, one for finance, one for compliance, paper for logbooks, apps for monitoring. Each good at its job. None talk to each other.
YOS replaces the stack and connects the data. Every module built to the standard of dedicated industry leaders — but integrated where standalone tools can't be.
Works offline at sea. Syncs at port.
Every action logged. Every deletion recoverable.
Every module exists because someone on watch needed it — not because a product roadmap suggested it.
