About The Sports Centreline Series

Completely re-engineered from the ground up, Since 2024 Sports Centreline Series sets a new benchmark for the humble Tinnie trailer. The new series has evolved from customer, dealer and boat manufacturer feedback, combined with over 56 years of design experience, addressing small issues that stock Tinnie trailers face, and blowing them out of the water in other areas.

This game changing new series boasts a 60% increase in roller count, along with a brand new roller rack keel ladder system, additional cross members and new cradle geometry, all providing big increases in hull support and protection.

Launch and retrieve is dramatically improved with an impressive 200% increase in approach angles, a unique redesigned rear cradle and new entry guides, plus a novel new “Big Mouth” roller bracket that all combine to make sure your Tinnie sits straights every time.

The new Sports Centreline Series not only makes a splash with usability and functionality, it’s tough and rugged as well. Built from durable galvanised steel, it features new heavy duty checker plate light brackets that incorporate a tie down point and handy rear steps. Plus of course an additional cross member up forward to support the increased loads that come with trolling motors, electric anchor winches and advanced battery systems.

• The Sports Centreline Series boasts our revolutionary “Undercarriage” system, meaning that the entire axle, spring and guard assembly can be moved forwards or rearwards on the main frame. This allows for the precise fine tuning of your trailer to provide the perfect tow weight on the back of your car. With the perfect tow weight comes smooth, effortless towing and greater comfort and safety when you are out on the road.
• Lastly are the Centreline series side skids which are larger than any other model in the line up. They are fully adjustable and when set up correctly will ensure that your boat sits level in the frame and is supported along the key load bearing areas of the hull. Manufactured from heavy duty galvanised steel, they won’t warp, twist or rot (like timber or some cheaper plastics in the market today), so you can be assured that your hull is being protected as you tow.
