What ABS Nautical Systems and SupaMaritime each cover, where they overlap and where they do not.
Free 30-minute demo · No commitment
ABS Nautical Systems is the fleet management software business of ABS Group, an affiliate of the American Bureau of Shipping classification society. Its NS product line, long known as NS5, covers maintenance, procurement, safety and compliance for commercial fleets and has a long track record with tanker, bulk and other deep-sea operators.
SupaMaritime, built by SupaSailing S.L. in Palma de Mallorca, is a set of separate web apps for commercial operators. Ferry and Merchant cover planned maintenance and work orders by calendar or running hours, the equipment register and onboard inventory, defects, crew certificates with expiry alerts, hours of rest checked against MLC and STCW limits, and ISM, ISPS, SOLAS or MARPOL records. Agent covers the port-agency side: port calls, PDA/FDA disbursement accounts, crew changes and deliveries. Each module is its own app with its own database, hosted in the UK (London) with application servers in Paris, under a GDPR Data Processing Agreement. Ferry and Merchant have a free plan and a Pro plan at €199 per vessel per month plus VAT; Agent is quoted on request.
The two overlap on maintenance, crew and compliance records for ferries and merchant ships. ABS NS is an established enterprise suite; SupaMaritime is a smaller set of web apps that also includes a port-agency module. SupaMaritime has no public API or webhooks for these modules, no on-premise option and no SOC 2 or ISO 27001 certification, and it does not do predictive maintenance, emissions reporting (CII, EEXI, FuelEU, EU MRV), voyage planning or chartering. This page sets out where each one fits.

When ABS Nautical Systems is the better choice
ABS Nautical Systems is the better choice when you want a long-established fleet management suite from a vendor affiliated with a classification society, when your fleet already runs it with years of maintenance history, or when you need something SupaMaritime does not offer, such as on-premise deployment, a public API for integrations, predictive maintenance, emissions reporting or a SOC 2 / ISO 27001 certified supplier.
When SupaMaritime is the better choice
SupaMaritime can fit better for ferry and merchant operators who want planned maintenance by calendar or running hours, onboard inventory where parts used come off stock, defects, crew certificates, MLC/STCW hours of rest and ISM, ISPS, SOLAS or MARPOL records in one browser-based app, starting on a free plan with published Pro pricing (€199 per vessel per month plus VAT). It is also relevant when a port agency in your group needs port calls and PDA/FDA disbursement accounts, which the Agent module covers.
