On 14 May 2026, the Greek Ministry of Maritime Affairs and Insular Policy released a national system for submitting crew lists online. The platform, called e-Ναυλοσύμφωνο (e-Charterparty), is reachable at echarterparty.yna.gov.gr.
Greek fleet operators no longer need to carry crew lists into port authority offices by hand. The whole process runs in your browser. Yacht charter fleet operators submit the crew list party, build the manifest, and finalize it. It’s a great first step to modernize yacht charter operations.
What e-Ναυλοσύμφωνο (e-Charterparty) Replaces
Up to now, registering any crew list in Greece meant physical paperwork, manual cross-checks at port authorities, and administrative drag that quietly eats hours during the season. Minister of Maritime Affairs Vassilis Kikilias announced the launch at the port of Lavrio, as a great step in the digital transformation of Greek maritime tourism. The goals are reducing bureaucracy, digitalization of charter operations, strengthening the country’s ports, and supporting local economies.
What changes: Greek crew lists are submitted electronically and in real time, without anyone showing up at a port office. Crew and passenger manifests are built and finalized online. Floatist now also supports the export of crew lists compliant with the greek regulations. This means your team only needs to click export and upload the files into the system.
The Two Statuses That Define Your Workflow
The platform focuses on two states a request can be in. First, SUBMISSION, then FINALIZATION. Getting these wrong is the fastest way to create problems for your base team.
SUBMISSION is the editing phase, where everything can still be changed, added, or deleted. Once you submit, the crew list moves into finalization.
FINALIZATION means the charter party has been submitted, and the manifest is locked for full name, ID number, sex, nationality, date of birth, embarkation date, and embarkation port.
Build the manifest properly during SUBMISSION. Fixing things after approval isn’t an option.
Crew Manifest: What’s Required
The crew field covers the captain and any professionally employed crew. Everyone else on board counts as a passenger. Don’t mix them up, the system treats these roles differently and applies different rules to each.
For each crew member you need a full name, ID or passport number, sex (M or F), nationality as an ISO alpha-3 code (GRC, ITA, GBR, not “Greek”), date of birth, embarkation date and time, and embarkation port. At least one crew member is required once the charter party reaches FINALIZATION. If you need to swap crew mid-charter, record a disembarkation for the outgoing captain and add the new one.
Passenger Manifest: Where Most of the Work Happens
Passenger fields follow the same requirements as crew, plus an optional notes field that stays editable forever. Two rules to keep in mind: the number of passengers cannot exceed the vessel’s maximum capacity for the selected usage type, and the system enforces this automatically.
A charter boat licensed for 8 passengers might have a different limit under another contract type. The system reads from the vessel record, so make sure your registry data is clean.
Bulk Import Saves Your Time And Nerves
The feature that justifies switching to e-Ναυλοσύμφωνο from day one is the Excel bulk import. Instead of typing eight or twelve passengers per boat on a Saturday morning, while three other charter parties are queued behind you, you upload a spreadsheet.
The template is downloadable from inside the platform and includes a data sheet, a Nationalities reference sheet with all valid ISO codes in English and Greek, and an instructions sheet covering date formats.
Two things to understand when using Excel to create the e-crew list:
- Format date columns as Text in Excel before entering dates. Excel’s regional auto-formatting will silently rewrite “2026-07-01” into something the parser doesn’t like.
- Use the 3-letter ISO code from the Nationalities sheet rather than the country name. “Italian” gets rejected, “ITA” works.
Bulk import is only available during SUBMISSION status, and only when the manifest is empty. If you’ve added one passenger manually and then try to bulk import, the option is gone. Build the spreadsheet first, upload once, then make individual edits afterwards.
The parser shows a preview before committing. Review it carefully. If there are errors, the system points to the exact row and field that failed.
Nationality Codes: The Small Detail That Trips People Up
Across the system, manual form, Excel import, and any future bulk JSON upload, nationality is recorded as an ISO 3166-1 alpha-3 code. Three uppercase letters. No free text is accepted anywhere.
The manual form has a searchable dropdown that accepts partial matches in English or Greek. The Excel template includes a full reference sheet. Anything else gets rejected with a clear error message.
Some codes you’ll use include GRC (Greek), GBR (British), USA (American), DEU (German), ITA (Italian), FRA (French), TUR (Turkish), and CYP (Cypriot). For everything else, check the reference sheet inside the template.
Common Errors and What They Mean
A few error messages come up repeatedly during your first month. Once you’ve seen them once, they stop being mysterious.
- “Modification is only allowed in SUBMISSION or FINALIZATION status”: the charter party has been completed or cancelled, no editing is possible.
- “At least one crew member is required”: the system won’t let you finalize without a captain, so add one.
- “Cannot set disembarkation details when adding a new member”: save the person first as “On Board”, then use the disembark action separately.
- “Disembarkation date cannot be before embarkation date”: exactly what it says, the validator is doing its job.
- “Field X cannot be modified after finalization”: core fields are permanent post-approval. If there’s a real data error, contact the responsible port authority directly.
- Excel: “Unrecognised nationality”: almost always means free-text country names instead of ISO codes. Copy the exact 3-letter code from the Nationalities sheet.
Greece Joins the Digital Charter Era
This is worth celebrating. Greece runs one of the largest charter fleets in the Mediterranean, with thousands of yachts moving in and out of bases from Athens to Lefkada to Kos every Saturday of the season. The country has now built the digital backbone to support charter operations.
e-Ναυλοσύμφωνο (e-Charterparty) is live, and it lands Greece firmly in the same league as its regional neighbors. Croatia has been running eCrew for a long time, with charter companies registering crew and passenger lists online up to the moment of the vessel’s departure. That system has been the quiet backbone of how Croatian fleet operators handle compliance ever since.
How To Start With e-Ναυλοσύμφωνο (e-Charterparty)
If you’re a Greek fleet operator and you haven’t logged into echarterparty.yna.gov.gr yet, that’s the first task. The system uses TaxisNet or email-based login.
After that, the priorities are straightforward. Clean your vessel registry data, because maximum passenger capacities, usage types, and registration numbers all need to match what e-Ναυλοσύμφωνο expects. Download the Excel template and run a dry test with one boat. Get the date formatting right in a quiet moment rather than during a Saturday rush. Standardize how your base teams collect guest data pre-arrival, because cleaner input means a faster submission. And decide who on your team owns finalization, because once the button is pressed, the data isn’t editable anymore.
