This blue hatch cover for Lewmar Low Profile hatches from Oceansouth is custom-fitted for size 03. The cover protects the deck hatch from sunlight, UV exposure, and marine weather, and is tailored for a rectangular hatch with external dimensions of 301 × 246 mm.
The cover is made of 310 g/m² ATLAS Marine Grade Fabric in 100% solution-dyed polyester with UV inhibitors. The fabric is waterproof, water-repellent, breathable, and UV-resistant. The breathable construction reduces condensation buildup around the hatch, while the material's resistance to mold, mildew, and abrasion makes it suitable for marine environments.
The custom-fitted design features an elastic hem that fits snugly around the hatch frame, as well as a drawstring closure with a cord lock. Double-overlapped seams increase strength, and the cover is designed to remain in place whether the hatch is open or closed.
This version fits the Lewmar Low Profile Hatch size 03, including the hatch with part no. 39903030. The compatible hatch is rectangular, measures 301 × 246 mm externally, and has a height of approximately 10–30 mm. The dimensions describe the compatible hatch and not the flat-laid product dimensions of the cover.
When fitting, hold the drawstring in the cord lock, place the cover around the back of the hatch, and stretch it forward over the hatch. The elastic hem is tucked snugly under the frame. The cover is specifically designed for Lewmar hatches; for other brands or hatches with externally mounted hinges, a suitable universal cover should be used.
The manufacturer reference for the blue version is MA 411-03B, while the base reference for the series is MA 411-03. The cover can be cleaned and maintained without special installations or separate mounting kits.
