Lewmar Ocean Hatch Size 10 Flange Base, Anodised Aluminium Frame, CE Area 2

The Lewmar Ocean Hatch Size 10 Flange Base is a marine deck hatch built for durability and long-term corrosion resistance aboard boats of all sizes. Its frame is machined from anodised aluminium, a finish chosen specifically to withstand ongoing exposure to saltwater, UV, and the general wear of life on deck. The hatch uses friction levers to hold the lid open securely in any position up to 95 degrees, so it stays put whether cracked for ventilation or fully raised for access, without a separate prop or stay to manage.

This flange-base version is designed to mount with a flange profile, and its Size 10 rating makes it suitable for CE Area 2 locations, meaning it is rated for use on the deck, coachroof, cockpit, and transom of a boat. Rugged construction throughout is intended to provide reliable protection against the elements across a wide range of conditions faced on the water. Lewmar has manufactured marine hardware, hatches, and portlights since 1946, and this hatch reflects that focus on hardware built specifically for the marine environment rather than adapted from general-purpose components.

Owners replacing an aging or leaking deck hatch, or outfitting a new build, can specify this unit by its part number, 39610070, to ensure they receive the correct size and base configuration.
