Tarpaulin fabrics have to withstand a great deal on board. They are exposed to UV radiation and the elements for months on end and can chafe against the railings, shrouds or fittings. Ultracover Marine is a tarpaulin material designed for such applications. The material consists of polyester ripstop and a multi-layer PU coating. With a weight of 200 grams per square metre, it is designed to remain relatively easy to handle, even when used for large tarpaulins.
Ultracover Marine is designed for full boat covers, winter and sun covers, boom covers and jib bags. The YACHT article on the Protective covers for headsails. According to the distributor, however, the material is not currently intended for use in sprayhoods. Ultracover Marine is available in the colours Snow, Platinum, Graphite, Desert, Kingsblue and Navy Blue. According to the manufacturer, the roll width ranges from 175 to 180 centimetres.
A distinctive feature of the material is that it does not contain any PFAS-based water-repellent treatments. This group of substances is often referred to as ‘forever chemicals’ because many of the compounds are highly persistent in the environment. The supplier states that Ultracover marine is finished without PFAS and that the PU coating does not release migratory plasticisers.
Even with a PFAS-free tarpaulin, proper care remains crucial to its lifespan. Dirt, salt and organic deposits should be removed promptly. How to Have your sprayhood and cover cleaned gently, explains YACHT in a practical guide. Anyone looking for suitable products will also find a Test of tarpaulin cleaners.
According to the supplier, the weaving, dyeing, coating and manufacturing processes are carried out entirely in Germany. Exclusive distribution is handled by Günter Schmitt Textilvertrieb on the island of Reichenau. Ultracover is sold exclusively to boat upholsterers and other specialist firms.
There is no fixed price for a finished boat cover. As well as the amount of fabric required, the cost is determined primarily by the type of boat, the cut, any reinforcements, zips, attachment points and the amount of work involved for the upholstery workshop. The manufacturer provides further technical details and contact information on its page at Ultracover Marine.
