Choosing LED navigation lights is not just a styling decision. For sailing yacht owners, it’s about compliance, reliability and long-term durability in one of the harshest onboard environments. With the launch of the Mantagua NAVISLIM range, we are introducing a fully certified range of LED navigation lights designed specifically for modern cruising yachts.
NAVISLIM sits confidently within the wider Mantagua marine lighting portfolio, offering a refined, low-profile alternative to more traditional housings while retaining full COLREG-compliant certification and serious marine-grade construction.
Fully Certified COLREG-Compliant LED Navigation Lights
One of the strongest aspects of the NAVISLIM range is its certification.
All NAVISLIM marine navigation lights are:
- Wheelmark certified – 60427/XX MED
- ABYC C-5 compliant
- Red Ensign approved – 76057/XX UK
This is not a decorative lighting range. These are fully tested, COLREG-compliant navigation lights suitable for offshore and coastal cruising yachts.
Wheelmark (MED) certification confirms compliance with the European Marine Equipment Directive. ABYC C-5 ensures conformity with American Boat & Yacht Council standards for navigation lighting. Red Ensign approval confirms acceptance under UK maritime authority requirements.
| Certification | Standard | Geographic Relevance | What It Confirms |
|---|---|---|---|
| Wheelmark (MED) 60427/XX | European Marine Equipment Directive | EU / EEA | Compliance with COLREG photometric and construction standards |
| ABYC C-5 | American Boat & Yacht Council | USA | Conformity with US navigation light installation and performance standards |
| Red Ensign 76057/XX UK | UK Maritime Authority | UK / MCA vessels | Acceptance under UK flag regulations |
For yacht owners refitting or replacing existing navigation lights, this means confidence that the product meets recognised international safety standards.
Slimline LED Navigation Lights for Modern Yachts
As the name suggests, NAVISLIM is defined by its low-profile form.
The housings are compact and discreet, available in both horizontal and vertical mounting formats. This makes them ideal for installation on cabin sides, coamings, pushpits, mast brackets or deck surfaces without the bulk traditionally associated with LED navigation lights for boats.
Available in black or white housings, NAVISLIM integrates cleanly with contemporary yacht styling while maintaining full regulatory compliance.
Despite their compact footprint, these are not lightweight consumer-grade fittings. The housings are manufactured from UV-stabilised PC + ASA, a high-performance marine engineering polymer blend. Polycarbonate provides impact resistance and structural strength, while ASA ensures long-term UV and weather resistance. The result is a tough, colour-stable housing designed for permanent exterior installation in demanding marine conditions.
All units are fully sealed to IP67, protecting the internal LED components from water ingress, salt spray and vibration.
Complete LED Navigation Lights for Sailing Yachts
NAVISLIM covers the full core lighting requirements for sailing yachts up to 20 metres LOA, including:
- Port and starboard sidelights (112.5°)
- Combined sidelights
- Stern lights (135°)
- Masthead (steaming) lights – 2NM and 3NM versions
- Convenient twin and three-light kits

The masthead range is clearly structured for compliance:
- 2NM = For vessels under 12m LOA
- 3NM = For vessels 12m–50m LOA
This makes it straightforward to select the correct LED masthead light based on vessel length when upgrading or replacing existing fittings.
The vertical three-light kit (port, starboard and stern) effectively serves as NAVISLIM’s deck-level tricolour alternative, offering flexible installation without relying on a single integrated lantern at the masthead.
Energy Efficient and Low Maintenance LED Navigation Lights
All NAVISLIM LED navigation lights operate on 10–30V DC, making them compatible with both 12V and 24V onboard systems. Power consumption is low across the range, helping to reduce battery load during extended night passages.
LED technology provides:
- Immediate full brightness
- Long service life
- Strong vibration resistance
- No bulb replacement
For cruising sailors undertaking longer passages, reduced maintenance and dependable performance are significant advantages.
How NAVISLIM Fits Within the Mantagua LED Navigation Light Range

NAVIPRO and NAVIPRO Compact are robust, established LED navigation light ranges known for durability and practical installation across a wide variety of vessels. They are well suited to straightforward replacements and traditional installations.
CLASSIC LED navigation lights provide a more conventional aesthetic for yachts seeking a familiar look.
TINY focuses on ultra-compact LED navigation lights for boats where space is extremely limited.

- Certified LED navigation lights for sailing yachts and cruisers
It is particularly well suited to modern cruising yachts where owners want fully certified marine navigation lighting without bulky housings.
