Seafy · Push-to-Talk for crews

Every order gets through. To the whole crew, every time.

Seafy P2T turns your crew's own smartphones into a professional radio network running on the ship's WiFi. No dead zones, no per-user fees, no risk of a message going unheard — even a thousand miles from shore.

The problem

Communicating onboard costs too much and works badly

Internal shipboard communication is stuck with 1980s technology. The result: delayed manoeuvres, badly handled emergencies, recurring costs.

Shared VHF channels

Few channels, constant interference, no digital features.

Dead zones

Engine room, lower decks, areas shielded by metal.

No traceability

Who said what, and when? No log for onboard documentation.

High running costs

Maintaining and replacing radio equipment, device by device.

Satellite dependency

Cloud solutions: expensive, slow, unusable at open sea.

The solution

A server installed onboard and a mobile app for the crew turn the ship's Wi-Fi network into a professional communication system — with voice, operational channels, chat and emergency management, with no need for an Internet connection.

Seafy P2T is a digital push-to-talk system for maritime crews that turns onboard smartphones into professional radios, running entirely over the ship's WiFi, 100% offline with no internet or cloud. It provides per-department channels (bridge, engine room, deck), a priority-override emergency channel, encrypted voice and no perceptible delay. Licensed per vessel, built by IES Italia (Milan).

How it works

Operational in less than an hour.

1

Install the server

Pre-configured hardware: connect it to the ship's WiFi and power it on. Installation via USB, no internet required.

2

Register the crew

From the dashboard: roles, channels, ID and PIN for every user. Onboarding a new crew member takes two minutes.

3

Communicate

The crew opens the app and presses the PTT button. Nothing else to learn, nothing else to carry.

What you gain

Fully offline

The server is physically onboard: it works at open sea, in port, anywhere. Zero dependency on internet.

No cloud subscription

A perpetual licence per ship, not per user. One purchase covers the whole crew.

Security

Encrypted audio, personal-code access and anti-intrusion lockout.

Better audio than radio

Optimised professional voice, no perceptible delay, clear even in the engine room.

No hardware to hand out

The app runs on the crew's own phones: nothing to lose, nothing to replace.

Full audit trail

Who spoke, when, on which channel and for how long — plus persistent chat history, in the owner's own infrastructure.

Interactive demo

Press. Talk. The whole department hears you.

Half-duplex, exactly like a radio — but the floor is granted by the server: one speaker per channel, deterministic priority, and an emergency that overrides everything. Hold the button to simulate a transmission.

  • Press-to-audio under 100 ms
  • One person at a time, no overlapping voices
  • Emergency interrupts every channel

Everything the crew needs

Instant push-to-talk

Press and speak: whoever has the floor is heard by everyone, with priorities handled automatically.

A channel per department

Bridge, engine room, deck, safety: each with its own channel, no interference.

Text chat

Group and direct messages, with persistent history.

Roles and chain of command

Captain, Officer, Crew, Admin — with a permission matrix per resource.

Admin dashboard

Users, channels and roles, real-time monitoring, full logs — from any browser.

Channel management — group, direct and broadcast channels, with roles and members.

EMERGENZA

When every second counts

Man overboard, fire, medical emergency: the system guarantees that nobody is left out of the conversation.

Absolute priority

Activation automatically interrupts every transmission in progress, on every channel.

Reaches the whole crew

Every online client is forced onto the emergency channel: red screen, vibration, audible alarm.

Logged, always

Every event stays in the logs for onboard documentation — non-deletable, exportable.

One system, every kind of ship

From a 15-person superyacht to a cruise ship with 800 crew across 12 decks.

Cargo

200 m container ship, 25 people, departments 150 m apart: per-department channels and clear audio in noisy areas.

Cruise

800 crew on 12 decks: unlimited channels, granular role management, dashboard for the operations centre.

Luxury yacht

60 m superyacht, 15 people, discreet service: Bluetooth earpiece, no radio visible to guests.

Ferry

Ro-ro, 40 people, weekly rotation: two-minute onboarding, instant user activation and deactivation.

Military / Coast Guard

Patrol vessel, 60 crew: comms that can't be intercepted over radio, federation disableable for air-gapped installations.

Licence per ship, not per user

One purchase covers the whole crew. Indicative prices, customisable per owner — multi-ship discounts available.

Technology

A communications hub onboard, fleet oversight from shore

Each ship operates in full autonomy, while the fleet can be managed centrally. An architecture designed to ensure operational continuity, security and scalability even in environments with limited connectivity.

Clear voice, no dropouts

Communication comes through clear and instant, with no dropped audio and no echo, even when several departments talk at once. Voice stays high-quality from first second to last.

One orderly channel, never overlapping

One person speaks at a time: whoever has the floor is heard by everyone, with no voices talking over each other in critical moments. The system is monitored constantly and frees the line instantly.

Your data stays onboard

Every message, channel and log stays on the ship, owned by you, never routed through outside servers. Nothing is lost, everything is tracked and always recoverable, with automatic backup.

Autonomous at sea, overseen from shore

The ship communicates fully on its own even with no internet; when a connection is available, data syncs automatically with headquarters, losing nothing in between.

Protected communications, controlled access

Every conversation is encrypted and every login is protected by a personal code: only authorised crew get in, and each session expires on its own.

Fast to install, simple to update

The system installs onboard in a few hours and updates with no specialist technicians, identical on every ship in the fleet — even from a simple USB stick, with no internet.

Centralized monitoring, real-time operational control

A web dashboard lets you monitor the platform status in real time, check service availability, oversee active communications and quickly spot any anomalies. All the information needed to ensure operational continuity is accessible from a single interface, both onboard and remotely where enabled.

Reliability proven in real conditions

Tested on the phones your crew actually uses, iPhone and Android, and on a remote link over the internet. The same instant response, across the whole fleet.

Handles hundreds of crew connected at once, with minimal footprint on onboard hardware: the server runs under 4% power and just 37 MB of memory. In sustained load tests: no errors, no disconnections, no lost communications.

Light, affordable hardware

A single audio stream takes about 30 kbps: minimal impact on the onboard network. Required: existing WiFi, 802.11 ac or better, 5 GHz recommended.

Safety first: the emergency override cuts through every channel and reaches everyone instantly. Critical words (mayday, MOB, fire) are highlighted automatically, with read receipts.

Control and compliance

Control and compliance: real-time monitoring dashboard, encrypted audio, a complete communications log for ISM Code obligations, retention by flag state, and two-factor access.

Self-contained onboard, ready for the fleet

Self-contained onboard, simple to extend: 100% on the ship's WiFi, no internet or cloud, instant communication with no perceptible delay. For fleets, ship-to-ship linking via satellite available as an enterprise option.

FAQ

Frequently asked questions

Seafy P2T runs 100% offline over the ship's onboard WiFi, with no internet, SIM, or cloud. A physical server installed on the vessel (mini server or rack) handles communication and transmits professional-quality voice with no perceptible delay. Crew smartphones become professional radios with per-department channels: bridge, engine room, deck.
