LEWMAR Ocean Series Hatches

Classic offshore hatch is installed onboard thousands of offshore boats around the world.

High-quality, durable hatches feature traditional high-profile styling with a bonded acrylic lens and external hinges. High lower-frame breakwater reduces the chance of water entering the boat when the hatch is open.

Ocean Series Hatches have 10mm thick acrylic lenses in sizes 10 to 40 and 12mm thick acrylic lenses in sizes 44 to 70 (other sizes available by Special Order). All sizes suitable for CE Area 2 (Deck, Coachroof, Cockpit and Transom)
