The operating manual for every boat you charter.
YachtOS keeps check-in and check-out evidence, fault reports raised at sea, cleaning and the Turkish, English and Russian guides sent to captains in one boat and equipment record.
The windlass how-to video, its handover photo and its fault history sit on the same line.
There is no price list. Each quote is based on fleet size, languages and setup scope.

The same four faults, every season.
In yacht charter, problems usually start in the process before they reach the boat. As in any manual: symptom, cause, remedy.
| Symptom | Cause | In YachtOS |
|---|---|---|
| Damage turns up at return, and nobody agrees whose charter it happened on. | The handover is on paper; the photos are on a staff member’s phone or in a chat group. | A checklist per boat, required photos tied to items, check-out side by side with check-in values, and a PDF report the captain sees. See Fig. 3–6 |
| At sea, the captain can’t start the generator and calls the office. | Equipment is explained verbally at each handover, in a hurry and often in one language. | Videos and guides tied to the equipment on that boat, in the captain’s language. They open offline in the mobile app. See Fig. 9–10 |
| Faults are reported by phone; nobody knows who owns them or when they were closed. | No record, no owner, no deadline; no fault history builds up per item of equipment. | Fault reports with evidence, assignment, SLA timer and history per item. A boat with an open critical fault is not handed over. See Fig. 7–8 |
| On turnaround day, nobody knows which boat is ready. | Cleaning and preparation are not tracked boat by boat. | Check-out opens the cleaning task itself. Check-in cannot start on a boat that is not ready. See Fig. 11–12 |

A handover report, with evidence.
Each boat has its own check-in template: shared items plus additions specific to that boat. Staff tick off items on a tablet or phone and attach photos to them. The check-out template is generated from the check-in; readings appear side by side and the difference is calculated.
- The template is frozen at the time of charter; later edits never change past records.
- The PDF report is generated in the captain’s language, Cyrillic included.
- The captain accepts the report or disputes it with a written reason; the dispute is recorded too.
| Item | Check-in | Check-out | Difference |
|---|---|---|---|
| Engine hours, port | 812 | 839 | +27 h |
| Engine hours, starboard | 809 | 836 | +27 h |
| Generator hours | 1,102 | 1,131 | +29 h |
| Fuel | 4/4 | 2/4 | −2/4 |
| Freshwater | 4/4 | 1/4 | −3/4 |
| New damage | — | 1 | Starboard bow, gelcoat scratch, photographed |


A fault at sea becomes an owned record in the office.
The captain reports the problem from their phone and adds a photo. With no signal, the report waits on the device and is sent as a single record once a connection returns. Operations sets the severity and assigns a technician; the SLA timer starts.
- Report
Reported
By captain or staff, offline included. With a photo and the equipment selected.
- Triage
Acknowledged
Severity, affected equipment, person responsible.
- Response
In progress
Comment thread, new evidence, running SLA timer.
- Closure
Resolved
Resolution note. The record is added to the equipment’s history.
Critical severity: the boat is locked for its next check-in
- Acknowledgement target: Reported → Acknowledged
- Resolution target: Reported → Resolved

A boat with an open critical fault is locked for its next check-in. Only an authorised person can unlock it, with a written reason.
YachtOS is not an emergency system. When a critical report is opened, 112, Coast Guard 158, VHF channel 16 and your company’s 24/7 line appear on screen.
The captain finds the right guide in their own language.
Content is linked to an equipment model, a boat model or the equipment of a single boat. Captains only see content for equipment on the boat they chartered: on a boat with a different engine, that engine’s video does not appear.
- Search works in Turkish, English and Russian: “engine won’t start”, “windlass how to”.
- The mobile app downloads a content pack; it can be read and watched offshore without internet.
- Safety content is never published without human approval; each language is approved separately. When the source text changes, translations are marked as outdated.
- AI Studio drafts transcripts, translations and dubbing; the editor decides what is published.
Captains don’t create an account. After check-in they sign in with a one-time code sent by SMS or email; access is limited to the charter period.


Turnaround day, boat by boat.
When check-out is complete, a cleaning task opens automatically and is assigned to the crew. Once the task is closed with before and after photos and approved, the boat is ready. Check-in cannot start on a boat that is not ready; a forced exception is recorded with its reason.
A sample Saturday, Göcek
- Poyraz check-out. 1 new damage, photographed.
- Cleaning task opened and assigned to the crew. Target: 3 hours.
- Cleaning approved. Saloon, galley and 3 heads photographed.
- Poyraz ready.
- Poyraz check-in. New captain, Russian.
Sample data: YachtOS pilot set


Who sees what, who changes what: you decide.
Roles are not preset; your company builds its own role matrix. Every permission comes with a scope: own records only, those assigned to them, or all. Someone without read permission cannot even see that a record exists.

- Permission changes and critical actions are written to an audit log.
- Each company runs on its own installation; your data never sits in another company’s database.
- KVKK/GDPR data requests and anonymisation of captain data are handled from the dashboard.
- Reports: fault resolution times, cleaning, content views, check-in completion.
How we start
- 1
Discovery
We review your fleet, your equipment list and your current handover forms together.
- 2
Pilot
We start with a few boats: templates, roles and the first guides are prepared, and staff are trained.
- 3
Season
The rest of the fleet is added. Your installation runs on a server dedicated to your company.
The interface is available in Turkish, English and Russian today. Adding a language is translation work, not a software change.
