Seafy, a maritime technology service from IES Italia, is presenting a shipboard push-to-talk system that lets crew communicate through smartphone apps over the vessel’s Wi-Fi, with an onboard server handling traffic locally. Seafy says that shipboard voice and messaging do not require internet, cellular, cloud, or satellite connectivity. The launch is reported in an indexed Assafina Online result dated 12 October 2026, but the article itself was not accessible; the available record does not establish additional launch details.
What Seafy P2T is and how it works
Seafy P2T is a shipboard communications system, not a standalone phone app. A server is installed aboard the vessel and connected to its Wi-Fi network. An administrator sets up crew accounts, IDs, PINs, roles, and channels in a browser-based dashboard; crew members then use the app and press a button to talk. Seafy describes the arrangement as a way to use the ship’s local network for communications without an internet connection. Seafy’s P2T product page and its business services page describe this architecture.
Because the server and Wi-Fi are onboard, Seafy says crew communications can continue when the vessel has no shore internet, cellular service, or satellite connection. This is a claim about the local shipboard system; it does not mean the system provides internet access or communicates with people outside the vessel when external links are unavailable.
What the launch coverage establishes
An Assafina Online search result dated 12 October 2026 is titled “Seafy Launches Offline Push-to-Talk System for Crews” and describes the system as part of Seafy’s onboard digital ecosystem. The underlying article could not be retrieved, so its indexed title and summary are the limit of what can be confirmed from that coverage. The accessible Seafy product and business pages explain how the company currently presents P2T, but do not independently establish when the service first became available or whether every advertised feature is deployed on customer vessels.

Features Seafy says the system includes
Seafy describes P2T as a half-duplex voice service: a user holds the floor to speak, and the server manages speaking turns. The company lists operational channels organized by department, group and direct text chat, user roles, communication logs, and a browser-based administration dashboard. Seafy also describes an emergency channel that can take priority over other channels, interrupt ongoing transmissions, and alert connected clients. These are vendor-described capabilities, not independently audited safety performance.
Seafy’s product page summarizes its offer this way: “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.” That is company wording, not an independent assessment.

Phones, Wi-Fi, and onboard equipment
Seafy lists Android 9 or later and iOS 15 or later, with iPhone 8 and newer identified for iOS. Its product page says an app registry can distribute the onboard app without internet. An indexed Apple App Store listing also says a running onboard P2T server and vessel Wi-Fi are required, but the listing page was not accessible; check the current storefront listing before relying on its details. Apple App Store listing.
The company’s stated infrastructure guidance varies by capacity. It recommends existing Wi-Fi at 802.11ac or better, with 5 GHz preferred, and estimates about 30 kbps per audio stream. Those figures are Seafy’s published requirements and recommendations, not an independent network design assessment. A vessel operator should have coverage checked in the actual working areas, especially across metal-separated decks and noisy spaces, before assuming that existing Wi-Fi will be suitable.

These are indicative, customizable prices published by Seafy, not a quote. The page also lists on-site installation, training, Android apps, and one year of support and updates as inclusions. It presents the iOS app, bridge integration, and audio recording as separately priced add-ons. The page’s more detailed hardware profiles specify a fanless mini server with 8 GB RAM, 256 GB NVMe storage, and a 15-minute UPS for under 50 users; a mini server or short-depth 1U system with 16 GB RAM, 512 GB storage, and a 20-minute UPS for 50–200 users; and a 1U rack with 32 GB DDR5, mirrored 1 TB drives, dual GbE bonding, and redundant power for 200–1,000 users. Ask Seafy to confirm which configuration, installation, licensing, and add-ons apply to a specific vessel.
How to evaluate the performance claims
Seafy’s product page publishes several figures without a separate test report or a stated independent benchmark. Treat them as company claims rather than verified operating results:
Rank #4
- National coverage: Utilizing 4G POC Push-to-Talk Over Cellular to achieve seamless communication, unlimited communication range, and coverage of up to 10000 miles. FCC Certification, FCC ID: 2BNNE-BQ-K28
- Lifetime free Sim card service: Comes with a Sim card, providing unlimited high-speed data service for life without monthly fees, subscription fees, or hidden costs. Provide unlimited range anywhere covered by cellular networks. (The SIM card is installed in the card slot and can be used after receiving the goods and opening them.)
- Security intercom: Not only does it support one-on-one private calls, but it also supports group encrypted call modes. It adopts advanced built-in encryption chips to comprehensively safeguard the security of voice and data transmission. It is an ideal walkie talkie for remote collaboration and data protection of professional security teams such as security and field work.
- Durable and sturdy design: The walkie talkie features a high-quality material body that is shockproof and drop resistant. Durable structure can withstand harsh environments and daily wear and tear.
- Clear audio: The AI-K28 is equipped with advanced noise-cancelling microphones that provide crystal clear sound quality. Effective communication can occur in any environment. And it has a group rental call function, which can achieve both group and private communication.
- “700+” communications delivered with none lost.
- 300 crew connected at the same time.
- “3,8%” server power at full load; the page also says under 4% power and 37 MB memory.
- Zero errors or disconnections under load.
- A product-page interactive demo claims press-to-audio below 100 ms, while the indexed App Store listing describes latency under 200 ms. These are differently worded claims, not confirmed real-world latency measurements.
The published material does not provide enough independent test detail to establish how these figures translate to a particular ship, network layout, or operating environment. Operators evaluating the system should ask for test conditions and arrange a vessel-specific demonstration.

Questions to settle before choosing a shipboard system
Seafy’s offer is one option for onboard communication; its own comparisons with handheld walkie-talkies, DMR, and cloud or satellite alternatives are vendor-authored. A practical evaluation should cover the vessel’s requirements rather than treating any one comparison as a neutral assessment.
