Ordered a bespoke cover for agricultural equipment. The quality of workmanship was great, and the cover works a treat. Easy to put on, yet easily survived two big gales and torrential rain. The business provides excellent quality combined with fantastic customer service - wish all businesses were like this. It was such a good product and lasted well over 7 years - we ordered a replacement and the same excellent service was provided.

Really pleased with my small trailer cover. Perfect size and the bungee fits the fixing points. Excellent durable material. Great service over the phone to check and re-check sizes. Cover was posted quickly. Thoroughly recommended. Thanks.

Very good quality and good service from Quote to Design to Completetion. There was a slight mix up with manufacturing but once the issue came to light it was resolved very quickly, mistakes happen but I always look in to how quickly and effective a company deals with it and Cunningham Covers resolved this very quickly.

From start to finish an excellent friendly and supportive service. Nothing was too much trouble. The product was a custom designed siding for our garden snug which was of excellent quality and fitted perfectly to where we planned to fit it. Fitting was simple and easy to do taking only about 2 hrs to fit. Highly recommend and for sure we are already looking at some more covers.

Sea Croc Towable Bladder

Cunningham have designed and engineered our unique and inventive method of transporting and storing fresh water, oil, wastewater and more. Our ‘Sea Croc’ is designed specifically to store and tow large volumes of liquid, for example, towing freshwater to site for treating fish against Amoebic Gill Disease (AGD). 

Amoebic Gill Disease is an infectious parasite found in water and targets the gills of fish. It develops because of poor water quality and in water bodies with dense fish inhabitancy, leaving fish farms extremely susceptible. When fish cross paths with this contaminated water, the added distress can cause decreased growth and even mortality.   

With our Towable Bladder, you can quickly and easily provide water to fish pens for rapid treatment! 

See more information on our Water Treatment Tarpaulins used within fish farms pens.  

Watch it in Action!

Benefits of Cunninghams Towable Bladder

Cunninghams Sea Croc’ Towable Bladder is made from very strong 1200g PU material, with a hard protective coating against abrasion and UV. This material is necessary to withstand strong currents and will have a longer life-span than less durable materials. The towable bladder has anchor points along the complete length of croc. It also has up to 5 loading/dispatch points and 2 inspection hatches. Our bags can be towed up to 6 Knots when at full capacity and 15+ Knots when empty. 

Flexible & Portable – As our Sea Croc is towed behind water vehicles, they can be easily transported to difficult to reach locations. Remote locations may not facilitate direct pipelines or transport access, so this alternative method is necessary.  

Reusable – Our anti-abrasion material allows for many years of use in and out of the water. This promotes sustainable practices and decreases the need for expensive alternative transport methods.  

Quick Deployment – With the automatic pressure valve, you can quickly inflate and fill. Off land, simply deflate the bladder and store for later use. 

Versatility – Our Towable Bladder can hold and tow up to 500m3 of liquid, allowing versatile use such as oil or waste water storage.   

Towable Bladder for Disaster Relief

Due to its size and durability, the towable bladder is also suitable for quickly and safely transporting large volumes of water for disaster relief efforts or to drought-stricken locations. In some circumstances, it may not be feasible for aircraft water deployment, so supplying water safely via sea may be required.
