Draft, issue and verify print-perfect magnetic compass deviation certificates in minutes, not days — and guide a ship's crew through a compass adjustment without sending anyone aboard. One vessel record for every adjuster and every flag.

A guided five-step wizard — vessel, conditions, correctors, deviations and review. Enter the 8-heading swing and the A–E coefficients and deviation curve calculate as you type.
A single A4 certificate carrying your firm's logo, stamp, signature and deviation curve, with a QR code that opens a live verification page showing whether it is valid, expiring, expired or superseded.
The vessel submits its swing readings, previous card and tray photos. You post step-by-step instructions, chat live with the bridge, review the residuals and issue the certificate straight from the session.
Corrector moves are calculated from compass-adjustment rules, not guessed. The AI explains the plan, answers follow-up questions and sanity-checks an instruction before it reaches the ship.
Upload a previous deviation card as a PDF or photo and its vessel, compass, deviations and correctors are read straight into a new draft. Or fill the Excel template offline and import it.
Every vessel is rated healthy, warning or critical from its coefficients and certificate validity, so you see which compasses need attention before a ship is caught out.
The adjuster, the ship and the fleet owner each get their own workspace on the same certificates — so nobody chases a PDF by email to find out whether a compass is in date.
Issue and renew certificates, manage the vessels you service and run remote calibrations — under your own firm's branding.
Each ship gets its own login to request a calibration, follow instructions from the bridge and keep its current card to hand.
Charterers, ship managers and P&I clubs follow certificate status across the IMO numbers they care about, with expiry and history per hull.
Built around
Certificate validity and the coefficient limits behind fleet health follow the IMO resolution and SOLAS Chapter V.
Certificates move from draft to issued to superseded, and any card can be compared side by side with the one it replaced — with every action kept in the audit log.
Compass adjusting firms first. Vessels use it to request and take part in calibrations, and charterers, ship managers and P&I clubs use a separate fleet view to follow certificate status across their ships by IMO number.
A single A4 page with your logo, stamp and signature, the vessel and compass details, correctors, the deviation table and curve, colour-coded coefficients and a QR code. It can be downloaded as a PDF or emailed directly from Binnacle.
Each issued certificate can have a share link and QR code. Anyone who scans it sees a live page confirming the certificate and its status — valid, expiring soon, expired or superseded. You can revoke a link at any time.
Yes. In a remote calibration session the vessel sends its swing readings and photos, you guide the crew through each adjustment with instructions and live chat, and you issue the certificate from the same session once the residuals are acceptable.
Certificate validity and the coefficient warning and critical limits used for fleet health follow IMO Resolution A.382(X) and SOLAS Chapter V.
Yes. Issuing, editing, sharing and calibration actions are recorded in an audit log with who did what and when. Adjuster and fleet-owner accounts can be protected with an authenticator app.
