Navigation Safety Increased with New Aids to Navigation

Application: Increase Navigation Safety at Main Ports
• 1500mm Buoys (SL-B1500)
• 2-3NM Solar LED Marine Lanterns (SL-60) in Red and Green with GPS Synchronization
Location: Anguilla (British Overseas Territory),
West Indies in the Caribbean Sea
Date: 2020


The island tourist destination of Anguilla is located in the Eastern Caribbean. It is the most northerly of the leeward islands. The flat, sandy island is only 35 square miles and 3.5 mi (5 km) at its widest point. It is renowned for its beautiful beaches, crystal-blue water, and tropical weather. Anguilla’s highest point is only 210 ft (64 m) above sea level. It has a population of approximately 15,000 inhabitants. The main island is surrounded by several small, uninhabited islets. Tourism is one of the main contributors to the island’s economy.

North Atlantic hurricanes plague the Caribbean from June to November. These tropical storms deliver high winds, large waves, and storm surges. The resulting damage can have crippling effects on the island’s economy. The tourism industry can be heavily impacted when a hurricane makes landfall on Anguilla. This is because tourist arrivals are negatively impacted before, during, and after the storm.


Anguilla’s hurricane and tropical storm casualties include aids to navigation (AtoNs). Over many years, floating AtoNs, including buoys and marine lanterns, have been lost. Other AtoNs detached from their moorings then floated away.

The risk was that some channels and port approaches were unmarked, posing a maritime safety risk to fishing and recreational vessels, cruise ships and their passengers, and most importantly, supply and cargo ships delivering food, water, and other essential supplies.

The Anguilla Maritime Administration is committed to maintaining rigorous levels of maritime safety for local and international vessels that call at its ports and harbours. Maintaining maritime safety is also required to ensure important economic drivers for the local economy are protected.


The UK Government [through the Foreign & Commonwealth Office and the Maritime and Coastguard Agency administered funds through the Conflict, Stability and Security Programme] assisted the Ministry of Infrastructure, Communications, Utilities, Housing, and Tourism with the purchase and installation of new AtoNs at Road Bay, an active port for hundreds of fishing, pleasure, and cargo vessels.

Sealite worked with the Anguilla Maritime Administration to identify the best AtoN combination for Road Bay. Sealite’s SL-B1500 Buoys combined with Sealite’s SL-60 2-3 NM Solar LED Marine Lanterns were deployed to provide visual demarcation of Road Bay’s main channel. Smaller pleasure and fishing boats can now identify the channel exclusion zone so large cargo vessels can approach without collision risk.

High traffic areas like Road Bay benefit from the stability of the SL-B1500’s large float section. The rotational molding process used to produce all Sealite buoys ensures a uniform wall thickness for excellent strength and durability. UV stabilized polyethylene, with added IALA-compliant color, helps keep buoy color robust throughout its service life, even in areas with strong UV profiles like the Caribbean. Closed-cell polyurethane foam deters water ingress if the buoy is punctured from vessel impact. Internal, stainless steel bracing connects the SL-B1500’s topside lifting ring and mooring eye for exceptional lifting strength on deployment or retrieval. Options include IALA compliant top marks, theft deterrent lantern cages, radar reflector, internal access hatch, and solar power supplies.

The SL-B1500 Buoys installed at Road Bay have unique detachment mechanisms at their mooring points. This will allow the Anguilla Maritime Administration to retrieve the buoys when major storms are forecasted, protecting their navigation assets.

SL-60 Solar Marine Lanterns were installed on the SL-B1500 Buoys. Their 2-3NM range ensures the buoys are visible at night and in foul weather. The lanterns are designed to be maintenance-free by utilizing energy-efficient, LED technology. LED life expectancy is 100,000+ hours. The SL-60s utilize a high grade, NiMH battery which is easily user-replaced.

GPS Synchronization was added to the SL-60 Marine Lanterns, allowing all lanterns to flash in unison. Unified flashing increases visibility for the Road Bay channel, enhancing safety for all vessels. With an expected life expectancy of 12 years, the SL-60 provides a low cost of ownership and excellent marine lantern value.


The new Sealite AtoN solution has successfully enhanced the safety of navigation at Road Bay. The Anguilla Maritime Administration will soon be installing an identical marking solution at Blowing Point, a passenger port. Blowing Point offers daytime ferry service to the neighboring island of French Sint Maarten and Dutch Saint Maarten. Coral reefs border the channel, limiting ferries and tourist travel to daytime, fair-weather operation only.

The new AtoNs at both of ports will easily be retrieved and redeployed before and after hurricanes. Vessels will be able to safely navigate after major storms, delivering important supplies to residents and visitors. The new AtoNs at Road Bay and future installation at Blowing Point will help increase maritime safety at two of Anguilla’s busy ports, adding value to the island’s important maritime and tourism industries.


“Sealite Aids to Navigation delivered the maximum benefit and value for our AtoN requirements. Sealite assisted us with developing a suitable layout for our port navigation requirements and went above and beyond to meet our deadlines. We look forward to working with them for Anguilla’s future marking requirements.”

What Our Client's Say

On behalf of Karachi Port I am pleased to acknowledge your good service and provision of the new SL-75 solar marine lanterns installed by your firm in the harbour channel at Karachi Port. The new lanterns are very feasible and useful and equipped with the latest navigational technology.

[Re: Sealite SL-LED Lightsource at LaCorbiere Lighthouse], We were impressed with Sealite’s solution which provided a modern, reliable and efficient light source whilst remaining sympathetic to the lighthouse’s heritage and significance as a local landmark, but most importantly to improve upon reliability and to continue its vital role in aiding the safety of navigation in Jersey’s waters, as it has done for nearly 130 years.

[Re: Sealite Wins Duke’s Choice Award for Java Technology & the Environment – Sealite GSM monitoring & control system]. The team at Motorola were extremely impressed with Sealite’s innovative integration of the G24-Java wireless module in their GSM Monitoring & Alarm System.

As one of your new distributors (Belize and Honduras, Waller Marine Belize LTD), I would like to express my congratulations to you and your people in providing reliable, dependable and inexpensive products. Formerly we were distributors for a Canadian made product but these were found to be too expensive for the market and also offered only difficult and complicated programming. Our first order of lights from you (SL15’s) took only four days to arrive from Aussie Land, when I opened the box they were still flashing. I tested a SL60 (white) for four days (steady on) before it required a recharge…remarkable. I will be placing another order shortly. Keep up the good work.

[Re: Installation of WindTalker for kite-surfing club], The WindTalker™ is a big success here in Cyprus, thanks to your after sales support the unit is now functioning perfectly.

-Christophe Meletiou

We choose to sell Sealite … this is a long story, well we treat Sealite as our own and the relationship we have developed with Jeff and Chris and their attitude and commitment towards growing Sealite to this stage is remarkable. We feel at home when talking to them and the staff of Sealite and this in turn gives us more security and strength in selling products in India.

-Aliasgar E Patrawala

[Re: Sealite Solar-Powered LED Area Lighting system], We chose the Sealite system for the Jacobs Well Queuing Pontoon due to our previous experience with Sealite’s product, its durability and construction.

-Peter Taylor

I just wanted to say thank you for the light and bracket Sealite supplied to Birkenhead Marina. As the other lights (old ones) need new batteries I will be replacing them with new lights from Sealite and the same brackets that you supplied with the light we received last week … Your product is excellent and the system of setting the light is good also. Thanks again for all your trouble.
