Danaos vs SupaMaritime: An Honest Comparison
How a long-established Greek ship management suite compares to SupaMaritime's modules for ferry, merchant and port-agency operators.
Free 30-minute demo · No commitment
Danaos Management Consultants is a ship management software company based in Piraeus, Greece, active for several decades. Its suite covers areas such as planned maintenance, procurement, crewing, chartering, accounting and HSE for shipowners and ship managers, and it is well known among Greek shipowners.
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 overlap is technical and crew management: maintenance, inventory, crew certificates and compliance records. Danaos is a broad suite that also handles accounting and chartering; SupaMaritime is narrower and does not. 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.

When Danaos is the better choice
Danaos is the better choice when you want one vendor across technical management, procurement, crewing, chartering and accounting, when you need accounting and chartering inside the same system as maintenance, or when you need a deployment model or integrations that SupaMaritime does not offer. SupaMaritime has no shipowner accounting, chartering or voyage modules, no public API and no on-premise option.
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.

Frequently asked questions
Is SupaMaritime a replacement for Danaos?
Only for part of it. SupaMaritime Ferry and Merchant cover maintenance, inventory, crew certificates, hours of rest and compliance records. They do not cover accounting, chartering, voyage management or emissions reporting. If you need those in one system, SupaMaritime is not a full replacement.
Does SupaMaritime include accounting?
Not for shipowners: Ferry and Merchant have no accounting module. The Agent module, for port agencies, handles PDA/FDA disbursement accounts, invoices and payments, can generate Italian FatturaPA e-invoices from the final DA and can export FDA disbursements as CSV journal entries for your accounting software.
How much does SupaMaritime cost?
Ferry and Merchant have a free plan with the dashboard, up to 50 contacts, 10 inventory items and 10 documents, no credit card required. Pro costs €199 per vessel per month plus VAT (€2,388 per vessel per year) and includes 5 crew seats per vessel; larger fleets can ask for a custom quote. Agent has no free plan and is quoted on request.
Where is SupaMaritime data hosted and how is it secured?
Application servers are in Paris and the Ferry, Merchant and Agent databases are in London, UK, which has an EU adequacy decision. A GDPR Data Processing Agreement is part of the terms every customer accepts. Data is encrypted in transit (TLS) and at rest by the hosting providers, access is role-based and scoped by organisation and vessel with row-level security, and multi-factor authentication is available. Databases are backed up daily and backups are kept for 7 days. SupaMaritime does not hold SOC 2 or ISO 27001 certification.
Can SupaMaritime connect to Danaos?
There is no standard connector and no public API for Ferry, Merchant or Agent.
