Rocinante by Plasmoid XPlanned maintenance that lives on board.
Rocinante runs the maintenance, rounds, logbooks, stores and safety paperwork of a yacht in one place. It runs on the vessel's own server, so the records stay aboard and the crew can work without an internet connection.

One system for the whole vessel
Built by someone who has run maintenance as crew, around how a vessel is actually run: by department, with heads of department in charge of their own.
Planned maintenance
Set a job up once and Rocinante keeps the plan running.
- By date or running hours, whichever comes first.
- Close a task with notes, photos, hours and the spares used. Stock updates itself and the next one is scheduled.
- A vessel database laid out by SWBS group, with each machine's history, manuals and spares.
- Defects get a corrective task and stay open until the fix is signed off.
Rounds, logbooks and procedures
Made for a phone in an engine room or on deck.
- Rounds with QR labels on the equipment. Ticks made without signal are kept and sent later.
- Engine room and deck logbooks, signed off by the head of department. Readings can feed the running hours.
- Step-by-step procedures with photos, kept on the phone to read with no signal at all.
Spares, purchasing and the wine cellar
Know what's aboard, where it is, and what's on order.
- Inventory with reorder levels, storage plans and a ledger of every movement.
- Purchasing from quote to delivery, with each item put away in the right box.
- The wine cellar for the interior team: take bottles out from a phone, stocktake, and a to-buy list.
Safety and the ISM paperwork
The safety management system alongside the maintenance, not in a separate folder.
- Read and confirm the SMS and procedures, with a record of who has.
- Incident and near-miss reports, non-conformities, audits and drills.
- Vessel and crew certificates with their survey windows, and renewal tasks raised in good time.
The captain's overview
Every department on one page, without opening each one.
- Departments overview: overdue work, low stock, spending and unsigned logbooks.
- Reports for any period, as PDF, Excel or CSV.
- Crew rotation and handover notes for each change-over.
- A drop box for crew to leave the captain a note, anonymously if they choose.
An assistant for each department
Ask in plain English. Answers come from the vessel's own records and manuals.
- It works as the person asking, with the same access, so nobody sees more than they should.
- Your choice of AI provider, including models run on board. Every action it takes is logged.
- Optional: everything else in Rocinante works without it.
Installed on the vessel, not in someone else's cloud
Rocinante is licensed per vessel and runs on a small server aboard. We set it up with you.
Your data stays aboard
The records live on the vessel's own server, on the vessel's network.
Works without internet
The crew carry on as normal at sea. Only updates and a cloud AI provider need a connection.
On every device
Installs as an app on phones, tablets and computers from the browser. No app store.
Access by department
Each department reads and writes its own records. Heads of department run their own.
A complete record
Every change is logged with who made it, and deleted items go to a recycle bin first.
Bring your history
We can bring across the records from the system you use today.
