Square hatch cover from Oceansouth is a universal protective cover for square deck hatches on boats and sailboats. This MA 400-4 variant has external dimensions of 500 × 500 mm and protects the hatch against UV exposure and weather.
The cover is made of blue ATLAS Golden Range canvas in 100% dope-dyed polyester with a fabric weight of 400 g/m². The material features a PU coating, a water column of at least 1,500 mm, and UV protection of UPF 50+ with a measured value above UPF 80. The fabric is breathable and helps to reduce condensation build-up around the hatch.
The wrap-around drawstring and integrated cord lock hold the cover securely around the hatch and act as an anti-wind fastening. The design does not require screws or permanent mounting hardware. The cover can remain in place when the hatch is opened and is held tight around the hatch when it is closed.
The polyester canvas has a light and weather resistance of 6–7 as well as a tensile strength of approximately 2,200 N in one direction and 1,400 N in the other. Elongation is approximately 40% and 30% in the respective directions. The material also has a chlorine resistance of 4–5, a water repellency rating of 100, and an oil repellency rating of 4.
The stated 500 × 500 mm are the product's external dimensions. They do not indicate a specific hatch cutout or compatibility with a specific hatch model, so the hatch's external dimensions and design should be checked before selecting a size.
