Built on board. Not in an office.
YOS exists because a working captain with an IT background spent years managing yacht operations with spreadsheets, paper logs, and disconnected tools — and decided to build something better.
The problem
On every yacht, captains and crew spend hours on administrative work that has nothing to do with their core job — navigating and maintaining the yacht.
Finance spreadsheets. Paper logbooks. Crew certificates tracked in folders. Maintenance schedules on whiteboards. Safety checklists printed and filed. Inventory counted by hand. None of these tools talk to each other, and none of them work offline.
Every system available was either built for merchant shipping and forced onto yachts, or built by software companies that have never stood a watch.
The solution
YOS was built by people who actually do the job. A captain with a university degree in information technology, backed by a crew of engineers, officers, and stewards who tested every feature in real operations.
The system was developed and beta-tested across several yachts in the Mediterranean — motor yachts from 50 to 110 feet, both private and commercial, operating under multiple flag states.
Every module exists because a real crew member needed it. Not because a product manager imagined it.
What YOS can do
Crew Compliance
STCW certificates, endorsements, and hours of rest — tracked and flagged automatically
Crew Passport
Download any crew member's full profile with all files, certificates, and data — organized and ready
Charter Operations
Booking and contracts to guest preferences and feedback — the full charter cycle in one place
IMO 4-Pillar Compliance
Safety, security, environmental protection, and working conditions — all tracked against flag state requirements
In Every Crew Pocket
A full operating system accessible from any device — bridge, engine room, galley, or shore office
AI-Powered Operations
Reads documents, detects expiring certificates, proposes maintenance — always under human command
Design principles
Built for sea, not for shore
Every feature works offline. We built YOS in conditions where connectivity is a luxury — because that is the reality of yacht operations.
Captains decide, software assists
The AI proposes. Humans approve. Nothing executes without explicit command. This is not a limitation — it is the architecture.
Every role, right access
A junior crew member cannot see finance. A head of department cannot approve their own expenses. Access is denied by default and explicitly granted.
No shortcuts, no vaporware
39 modules. 190,000+ lines of code. Running on working yachts in the Mediterranean. Not a pitch deck — a deployed system.
What YOS is — and what it isn't
Not a crew recruitment platform
Keep your entire crew in compliance — STCW certificates, endorsements, hours of rest, all tracked and flagged automatically
Not a CV builder or career service
Download a complete crew passport profile — all files, certificates, and data organized and ready to present
Not a charter booking system for guests
Handle the full charter cycle — from booking and contract to guest preferences and post-charter feedback
Not a merchant shipping compliance tool
Track full IMO 4-pillar compliance for your yacht — safety, security, environmental protection, and working conditions
Not a concept or pitch deck
Put a full operating system in every crew member’s pocket — bridge, engine room, galley, or shore office
