Square hatch cover from Oceansouth is designed for square hatches with an external dimension of 450 × 450 mm. The cover belongs to the Sailboat Hatch Cover – Square series and carries the model number MA 400-3.
The cover protects the hatch against UV exposure and general weathering. The breathable marine canvas also limits the build-up of condensation under the cover. The design allows it to remain in place around the hatch, both when the hatch is closed and when it is opened.
The material is blue ATLAS Golden Range marine canvas made of 100% solution-dyed polyester with a PU coating. The fabric has an area weight of 400 g/m², a water column of at least 1500 mm, and a UV protection factor of UPF 50+ with a stated material rating above UPF 80.
The adjustable drawstring with cord lock acts as an anti-wind attachment and secures the cover around the hatch without a separate, model-specific mounting kit. Select the size based on the hatch's documented external dimensions and square shape.
The material's technical properties include light and weather fastness of 6–7, tensile strength of approximately 2200/1400 N, elongation of approximately 40/30%, chlorine resistance of 4–5, water repellency of 100, and oil repellency of 4.
