How to Spot Your Boat at Night — Baywatt 4-Channel RF Remote
Which one is my Boat? (Night Mooring Edition)
Spot your anchored boat from shore with a 4-Channel RF Switching System
At night in a mooring field, anchorage, or busy marina, finding your own boat from shore can take longer than expected. Many hulls look similar in low light, and boats may swing with wind and tide. A simple and effective method is to switch on one or two distinctive lights—for example cockpit lighting or underwater lights.
With the Baywatt RF Remote Control System (868 MHz), you can control up to 4 onboard accessory circuits from shore. This wireless boat switch system is designed for marine 12/24V installations and focuses on practical integration: short wiring runs, clear status feedback, and configurable switching behavior per channel.
Typical operational range is 600m to 1km in open line-of-sight conditions (range varies with environment and conditions).

Key points (at a glance) • 4 channels (control up to 4 accessories) • 12/24V marine accessories control • Per-channel mode: ON/OFF or MOM/OFF • Status LED on receiver: red = OFF, green = ON • Optional fixed cockpit panel with permanent DC supply available on request |
What this system is
This kit is an RF switching architecture for 12/24V boats: a paired transmitter sends commands, and the receiver switches power to the selected circuit. The objective is straightforward: control common onboard accessories without running long control cables back to a helm panel.
Typical accessories controlled from shore
- Cockpit / courtesy lights (identify the boat quickly and prepare boarding)
- Underwater lights (strong visual signature around the hull)
- Alarm / siren circuit (arming or activation, depending on the installation)
- Horn (momentary command when appropriate)
Two configurations to control 4 instruments
The system can be implemented in two ways. Both options provide 4 controllable functions. The difference is the wiring topology: centralized receiver versus distributed receivers.
| Configuration | Best fit | Electrical principle | Typical benefit |
|---|---|---|---|
|
Option A 1 receiver / 4 channels |
Small boats (tender, dinghy, center console) Loads grouped in the same area |
One enclosure with 4 outputs. Max total load: 30A across the 4 outputs (load allocation depends on the installation). |
Compact architecture when accessories are close to each other. |
|
Option B 4 receivers / 1 channel each |
Larger boats / yachts Loads spread across the boat |
One receiver dedicated to one circuit. Up to 30A per receiver (per circuit). |
Distributed approach that can reduce long wiring runs by placing each receiver close to its load. |
Option A is designed for compact installations where accessories are near each other, since wiring still runs from the receiver to each instrument.
Option B is preferred when the boat layout would otherwise require longer harness runs, or when you want a dedicated 30A capability per circuit. Each receiver can be installed close to the equipment it controls, keeping high-current wiring local.
Optional fixed cockpit panel (on request)
In addition to the handheld transmitters, a fixed RF control panel designed for permanent DC supply can be supplied on request. This creates a dedicated onboard control point (for example at the cockpit), while keeping the benefits of RF switching for distributed loads.
This fixed panel is commonly used as an auxiliary boat panel for equipment such as: cockpit/courtesy lighting, work or search lights, pumps, or directional systems (when installed with appropriate control logic).
Per-channel setup: ON/OFF or MOM/OFF
Each channel can be configured depending on the function you want to control: ON/OFF for stable states, or MOM/OFF for momentary commands. This flexibility supports both lighting control and command-type actions.
| Mode | Behavior | Typical marine uses |
|---|---|---|
| ON/OFF | Press once: output ON. Press again: output OFF. |
Cockpit lighting, courtesy lighting, underwater lights, alarm arming, auxiliary accessories. |
| MOM/OFF | Output is activated only while the button is pressed (momentary command). | Horn command, pulse-type commands, directional commands when used with appropriate control logic. |
With four independent channels, the system can be assigned to directional commands (up/down or open/close). This approach can avoid installing an additional helm panel and can limit extra control harness runs across the boat.
Examples of applications (depending on your electrical design):
| Application | Recommended channel behavior | Notes |
|---|---|---|
| Aft platform (open / close) | 2 channels as MOM/OFF (OPEN + CLOSE) | Requires correct relays/contactors and safety interlocks as specified by the equipment manufacturer. |
| Davit (up / down) | 2 channels as MOM/OFF (UP + DOWN) | Directional systems must follow manufacturer wiring and safety logic. |
| Pumps (utility / deck wash / auxiliary) | Usually ON/OFF | Fuse and size cables correctly for the pump load. |
| Work lights / search lights | ON/OFF (or MOM/OFF for specific control schemes) | Ideal for remote activation before boarding or during maneuvers. |
Note: For moving equipment (platforms, davits, windlass control, etc.), the electrical design must follow the equipment manufacturer’s requirements, including correct relays/contactors and safety interlocks where applicable.
Status indication and troubleshooting advantage
The receiver provides output status indication via a bicolor LED: red = output OFF, green = output ON. The transparent lid allows instant reading for faster troubleshooting when needed.
This provides an immediate diagnostic benefit. If a load does not operate as expected while the receiver indicates green (ON), the fault is more likely downstream (device, connector, local wiring, ground return, or the accessory itself) rather than the RF command or the receiver output state. Conversely, if the LED remains red (OFF), the output is not enabled and the issue is more likely related to command state, pairing, configuration, or upstream power supply to the receiver.
In marine installations, this type of visual status feedback saves time because it helps separate control/state from load-side troubleshooting.
Installation principles (marine-oriented)
A reliable 12/24V installation is always based on fundamentals:
- Fuse each circuit according to the accessory and cable rating.
- Use marine-grade tinned copper cable sized for current and length.
- Mount the receiver(s) in a protected and serviceable location.
- Keep high-current runs as short as practical, especially on distributed layouts (Option B).
- Label circuits to keep future maintenance and troubleshooting straightforward.
Which option should you choose?
Option A: 1 receiver / 4 channels
Recommended when the boat is compact and the accessories are near each other. It provides a clean solution with minimal hardware and a centralized receiver.
Option B: 4 receivers / 1 channel each
Recommended when the boat has distributed equipment zones or when you want each circuit to have its own receiver close to the load. This can reduce long wiring runs and provides up to 30A capability per receiver.
Use from shore: practical, but always within responsibility rules
This RF system is intended for accessory circuits (lighting, alarm circuits, horn command, and other non-propulsion functions depending on the installation). The captain remains responsible for safe operation and compliance with local maritime rules. When operating onboard equipment, apply normal seamanship and safety practices.
