Lewmar Size 70 Flange Base Ocean Hatch, Satin Finished Aluminum, CE Certified Boat Deck Hatch

The Lewmar Size 70 Flange Base Ocean Hatch is a flat-mount deck hatch built for deck, coach roof, cockpit, and transom installations on boats. Constructed with an anodized aluminum frame, it is engineered to resist corrosion from ongoing exposure to sun, salt, and moisture, making it suited to long-term use in the marine environment. The hatch is finished in satin finished aluminum, giving it a clean, low-glare appearance that fits most boat deck layouts.

An integrated friction lever system holds the lid open in virtually any position up to 95 degrees, so the hatch stays put at the angle needed for ventilation or access without slamming shut. The flange base design allows the hatch to mount to any flat surface for straightforward installation, though mounting hardware is not included and must be sourced separately. As a Lewmar product, it carries the fit, finish, and material quality boaters expect from a brand widely used on boats and by boatbuilders worldwide.
