Gold Coast Waterway Authority plays an important role in managing and protecting the Gold Coast’s iconic waterways, and are responsible for 260km of navigable waters plus more than 750 hectares of lakes and dams.

In an effort to improve channel options, new navigation buoys have been established with the key action of enhancing the waterways, by completing the channel with navigation aids.

Due to a large number of aids to navigation within the Gold Coast waters, the Gold Coast Waterway Authority were eager to trial an alternative to traditional chain moorings with the objective to save in the replacement cost of chain plus reduce maintenance and handling costs.

Project Overview

As an alternative to traditional mooring, synthetic mooring provides a lightweight and environmentally sensitive option to standard chain and are ideal for many marine mooring applications. For this reason, the Gold Coast Waterway Authority made a decision to trial synthetic mooring to see if this option would benefit themselves, as well as already having a positive effect on marine life.

Traditional mooring components were 32mm ground chain with a 280kg concrete block used as a mooring weight, with the trial using 20 tonnes, 7-metre synthetic mooring with 250kg cast iron mooring
weight for an 18 month period.


After the trial period, the 2 mooring solutions were inspected and the synthetic mooring line was found to be in excellent condition, including the wear points on the thimbles and shackles. The decision to replace a vast majority of buoy moorings with the new synthetic solution was an easy choice, considering the cost of replacing chain due to corrosion and wear every 2-3 years when compared to synthetic mooring lasting 5-6+ years.

With the added benefits of reduced maintenance costs due to easier and shortened cleaning times, reduced handling costs and the fact the synthetic solution minimises damages to the seabed, the Gold Coast Waterways Authority were excited to reap the benefits of this solution and roll it out in future navigation aid projects.

Benefits of Synthetic Mooring

Synthetic mooring is made up of heavy duty nylon fibre construction and is covered in industrial rubber that protects the nylon from corrosion. The unique design of the embedded thimbles eliminates fraying of the nylon fibres, whilst the abrasion and cut resistant rubber is UV stabilised and salt water resistant allowing it to be virtually maintenance free for years.

The use of nylon and rubber materials ensures the mooring line is lightweight and very flexible whilst maintaining the break strength of the traditional chain. The lightweight solution means handling, installation and servicing is made easier with a reduction in heavy lifting and deployment equipment.

The Sealite synthetic mooring line is a high-performance solution, best suited for marine conditions and environments. With over 50 different types available, the Sealite synthetic mooring solution offers exceptional value in the market and is perfect for use in rivers, lakes, estuaries, harbours, bays and oceans.


  • Very flexible, lightweight and suitable with various attachment devices
  • Easy to install with galvanised or stainless steel thimble eyelets embedded into the rubber casing
  • The mooring line is UV stabilised and salt water resistant allowing it to be maintenance free for years
  • Abrasion/cut resistant rubber protects the inner nylon fibres from the elements and keeps out water, mud and creatures
  • Friendly to the marine environment
  • Multiple lengths to suit any application

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.

[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.
