PLUG INTO WHAT’S ALREADY THERE.
Sentinel Custom can do more than monitor your boat. Through BM-50 STANDARD or BM-50 PRO, Sentinel can become part of a broader onboard ecosystem, enabling remote switching and integration with compatible digital switching platforms.
Simple remote switching — out of the box
BM-50 STANDARD includes 1 built-in Remote Control Output and BM-50 PRO includes 2, allowing simple remote switching directly from the Sentinel app. You can control selected onboard equipment such as:
- Lighting
- Refrigerators
- Pumps
- Other supported onboard systems
Additional Remote Control Outputs can be added through Sentinel HUB.
Disclaimer
Some onboard equipment may require additional interface hardware depending on the system configuration and power requirements.
Integrate with existing systems
Sentinel can integrate with compatible digital switching and onboard monitoring systems such as CZone, EmpirBus, and Simarine — allowing deeper onboard visibility and expanded control possibilities through existing onboard infrastructure.
This means Custom can become part of a larger connected boating ecosystem rather than operating as a standalone monitoring device.
Disclaimer
Some integrations may require additional third-party subscriptions, hardware, certifications, or compatibility verification.

Why boat owners choose
Custom Bundle
Real reasons owners rely on Sentinel — and what it means for your boat day to day.
Some owners need advanced security.
Others prioritize engine data, digital switching, battery monitoring, or deeper onboard integration.
Instead of adapting your boat to a predefined package, Custom Bundle is configured around your exact requirements.
The result is a solution built specifically for your boat—with the flexibility to grow as your needs evolve.
LET’S FIND THE PERFECT SETUP
Still deciding?
Buying as a business?
If you’re purchasing a Sentinel bundle as a business, simply configure your bundle as usual and proceed to checkout. Enter your complete company and VAT details in the billing information.
When you place your order, your payment provider may temporarily authorize the full retail amount, including VAT. This is only an authorization — the final amount is determined before the payment is captured.
Our back office team will review the company and VAT information provided with your order. If your business details are successfully verified and the purchase qualifies for VAT-free treatment, we will capture only the net amount. The remaining authorized amount will not be charged.
Example:
Retail price including VAT: €1,200
Eligible business price excluding VAT: €1,000
Your payment method may initially show an authorization of €1,200. Once your business details have been verified, Sentinel will capture only €1,000.
If the company or VAT details cannot be verified, or the transaction does not qualify for VAT-free treatment, the applicable VAT will be charged.
How does the purchase process work?
There are two ways to purchase a Sentinel solution, depending on your needs.
Bundles
If you’re looking for a complete, ready-to-install solution, you can purchase one of our Sentinel bundles directly through our online store. Simply choose the bundle that best fits your boat and complete your purchase online.
Custom Solutions
If you have specific requirements or would like to create a custom configuration, our team can help. Simply contact us using the enquiry form, and one of our experts will guide you through the available options, recommend the right hardware and sensors, and prepare a tailored proposal for your boat.

I have specific needs and none of the bundles exactly match what I’m looking for. What can I do?
Absolutely. While our bundles are designed around the most common boating needs, they’re not the only way to build a Sentinel solution.
If none of the available bundles match your requirements, simply contact our team through the enquiry form. A Sentinel expert will help you select the right Boat Monitor, sensors, integrations, and subscription plan to create a solution tailored to your boat and how you use it.
The consultation and proposal process is completely non-binding, allowing you to explore the available options before making a decision.
Is my boat compatible with Sentinel?
Sentinel is designed to work with most modern yachts (20ft–90ft), integrating with:
- NMEA 2000 systems (engine monitoring, fuel tracking, etc.)
- Standalone sensors (battery, shore power, bilge, door/hatch security)
- Digital switching systems (CZone, EmpirBus, etc.)
Not sure about compatibility? Contact us at info@sentinelmarine.net (or via Contact Form) for a free assessment.
