Last updated July 23, 2026. Device support can change with firmware; confirm current settings in the manufacturer documentation before purchase.
How it connects
- TCP — the app dials the gateway (host + port). Reliable and ordered;
gateways limit simultaneous TCP clients (YDWG-02: 3). - UDP — the gateway broadcasts datagrams to the subnet; the app just
listens on the port. Unlimited devices can share one stream; no host to
configure. - No authentication anywhere — the boat's WiFi password is the perimeter.
Everything stays on the local network; works offshore with no internet. - Common ports: 10110 (Navico MFDs, ShipModul, convention), 2000
(Digital Yacht), 1456 (Yacht Devices), 39150 (Vesper).
iPhone and iPad: Broadcast UDP is not currently available on physical iOS devices. Use TCP or unicast UDP. Mac supports broadcast UDP.

Supported — dedicated WiFi gateways (their whole purpose)
| Brand | Model | Notes |
|---|---|---|
| Yacht Devices | YDWG-02 | NMEA 2000→WiFi; TCP (≤3 clients) or UDP; default port 1456; 3 independently configurable data servers |
| Yacht Devices | YDWN-02 | NMEA 0183→WiFi |
| Yacht Devices | YDWR-02 | 0183 WiFi router/multiplexer, 3 TCP/UDP servers |
| Digital Yacht | WLN10 Smart | 0183→WiFi; TCP/UDP port 2000; device at 192.168.1.1 in AP mode |
| Digital Yacht | NavLink2 | N2K→WiFi; TCP/UDP port 2000 |
| Actisense | W2K-1 / W2K-2 | N2K→WiFi; 3 data servers, TCP/UDP (W2K-2 is the current model) |
| Actisense | WGX-1 | combined 0183 + N2K WiFi gateway |
| ShipModul | MiniPlex-3Wi / 3Wi-N2K | 0183 multiplexer (+N2K/SeaTalk on -N2K); port 10110, UDP default / TCP option |
| Quark-elec | QK-A032 | budget N2K↔0183 gateway; TCP 192.168.1.100:2000 |
| DIY | Signal K / OpenPlotter (Raspberry Pi) | serves 0183 on TCP 10110 alongside Signal K |
Supported — AIS transponders with built-in WiFi
| Brand | Model | Notes |
|---|---|---|
| Vesper | XB-8000 | TCP port 39150 at 192.168.15.1; discontinued but common |
| Vesper (Garmin) | Cortex M1 | TCP 39150 at 10.1.1.1; Garmin documents third-party app use |
| em-trak | B952 / B954 | streams AIS + GPS + wired-0183 data; does not convert N2K instrument data |
Supported — MFDs with native NMEA-over-WiFi (Navico brands only)
| Brand | Models | Notes |
|---|---|---|
| B&G | Zeus² / Zeus³ / Zeus³S / Zeus S, Vulcan | Settings → Network → "NMEA 0183 over Ethernet/WiFi", TCP/UDP port 10110 |
| Simrad | NSS evo2/evo3/evo3S, NSO, GO | same Navico OS feature (NSX unverified — bench-test before claiming) |
| Lowrance | HDS Gen2 Touch → Carbon → Live → PRO, Elite Ti/Ti2/FS | same Navico OS feature |
Not supported directly — MFD WiFi is proprietary
These need one of the gateways above added to the boat's NMEA 2000 backbone
(the gateway hears every sensor on the bus directly; the MFD's cooperation is
not required):
| Brand | Models | Why |
|---|---|---|
| Garmin | all chartplotters (GPSMAP, ECHOMAP) | WiFi talks only to ActiveCaptain |
| Raymarine | Axiom / Axiom+ / Axiom 2 Pro/XL, Element | WiFi is for RayConnect + approved LightHouse apps |
| Furuno | NavNet TZtouch / TZT2 / TZT3 | proprietary NavNet protocol (Furuno's own apps only) |
| Humminbird | SOLIX, APEX, HELIX | One-Boat Network; 0183 exists only as a physical connector |
Direct NMEA 2000 (raw PGN) support — shipped
Additive: every device supported in NMEA 0183 mode keeps working
unchanged. Raw N2K unlocks instance-aware data (engine #1/#2, house vs
starter battery, tank levels) that 0183 structurally cannot express. Raw PGN
feeds come from dedicated gateways only — never from MFDs. All three
framings below are auto-detected; the supported framings are detected automatically.
| Device | Raw format | Framing | Status |
|---|---|---|---|
| Yacht Devices YDWG-02 / YDEN-02 | YD RAW | ASCII lines over TCP/UDP (hh:mm:ss.ddd R <CAN-ID> <8 hex bytes>) |
✅ Supported |
| Quark-elec QK-A032, Chetco SeaSmart | $PCDIN | raw PGN hex inside a normal 0183 $-sentence |
✅ Supported |
| ShipModul MiniPlex-3Wi-N2K | $MXPGN | PGN wrapped in an 0183-style sentence; mixed streams are normal | ✅ Supported (based on the vendor specification) |
| Signal K server (RPi / OpenPlotter) | any of the above, or Signal K JSON | configurable | ✅ Supported — configure it to emit YD RAW or $PCDIN (Signal K's own JSON is not read) |
| Actisense W2K-1 / W2K-2 | Actisense N2K / RAW | own binary + ASCII framings, needs a dedicated adapter | ❌ Not read — run the W2K in NMEA 0183 mode, where it works fully |
Yacht Devices RAW mode notes
- A YDWG-02 serves 0183 and RAW on different ports simultaneously —
switching modes in the app needs no rewiring. - RAW mode is enabled per data server in the gateway's own web UI.
