Yacht management software is a centralised platform that captains, management companies, and owners use to run a yacht's operational and regulatory workload from one place — replacing spreadsheets, paper logs, and disconnected apps.

Typical capabilities include crew HR management, vessel movements, crew records, certificates and document tracking, planned maintenance, safety management (SMS) under the ISM Code, drills and checklists, charter operations, and fleet-wide reporting.

Sealogical is a yacht management platform built specifically for superyachts and their management companies.

The ISM Code requires many yachts to operate a documented Safety Management System (SMS) covering procedures, drills, defect reporting, audits, and continuous improvement.

Sealogical supports ISM compliance by digitising the SMS: storing controlled forms and policies, scheduling and recording safety drills, tracking non-conformities and corrective actions, logging defects, managing certificate validity (DOC, SMC, ISSC), and producing audit-ready reports for flag and class.

Sealogical provides a full ISM-aligned safety module covering forms, drills, defects, permits to work, and audit-ready records.

Sealogical's Hours of Rest module is built directly to the MLC 2006 and STCW A-VIII/1 rest-period rules. Crew log rest intervals on any device, and Sealogical automatically validates each record against all five statutory tests:

Violations are flagged the moment they occur. At month-end, crew submit their sheet, an approver reviews and signs it off with a digital signature, and Sealogical generates an IMO-format report — a 24-column hourly grid with compliance badges and monthly summary — ready for flag-state inspection or audit.

Yes. Sealogical tracks both vessel certificates (e.g. SMC, ISSC, MLC, class, statutory) in the Certificates module and crew qualifications (e.g. STCW, medical, GMDSS) on each crew member's record, both with expiry tracking and alerts.

Every certificate has an expiry date, and a scheduled job emails the responsible crew and shore staff in advance of expiry so renewals and audits don't slip. Records are searchable, exportable, and retained for audit history.

Yes. The Charter module covers charter records from option to completion, a charter planner, guest lists with the IMO FAL Form 6 export, and charter documents. APA (Advance Provisioning Allowance) management is part of the Finance add-on: APA deposits, expenses, fuel records and adjustments are tracked per charter, with settlement statements at the end.

Guest records are kept securely separate from crew records and tied to specific charters.

Sealogical is multi-vessel by design. A management company can run one fleet or many, with crew profiles, qualifications, scheduling, and section-level permissions managed centrally.

Crew can be transferred between vessels in the same fleet without re-entering their records, and access is controlled at the section level (crew, safety, certificates, technical, charter, finance) so each user sees only what their role requires.

Fleet-wide reporting rolls up every vessel into one view for managers.

Sealogical is priced at €320 / £280 / $360 per vessel per month, which includes every module except the optional Finance and Deck Plans add-ons.

The Finance module is an optional add-on at €320 / £280 / $360 per vessel per month. It includes Accounting (a general ledger with bank reconciliation and financial reports) and crew payroll.

Deck Plans is an optional add-on at €80 / £70 / $90 per vessel per month, with a 30-day free trial on each vessel.

Sealogical offers an unlimited free trial with no credit card required.

Sealogical began life in 2003 supporting a fleet of 7 yachts, and has gone on to support over 1,000 vessels worldwide over the years, ranging from privately operated superyachts to large management-company fleets.

Customers include captains, senior crew, and shoreside management teams who use Sealogical as the system of record for safety, crew, certificates, maintenance, and charter operations.

The fastest way to get started is to book a demo at sealogical.com/contact. A member of the team will walk you through the modules relevant to your operation (private vs. charter, single yacht vs. fleet), set up a trial environment with your vessel data, and help your captain and crew onboard.
