Lewmar Low Profile Rectangular Deck Hatch, Size 10 - Anodized Aluminum

The Lewmar Low Profile Rectangular deck hatch, Size 10, is built for boat owners who want a flush-mounted opening without a raised profile disrupting the deck line. The frame is anodized aluminum for corrosion resistance in a marine environment, and the hatch projects only 25 mm above the surrounding deck, keeping foot traffic and lines clear of a bulky lid. The lid combines a seal and acrylic lens fitted into the aluminum frame, giving a leak-resistant closure while still letting light into the space below.

Outside handles let the hatch be opened from the deck when it is unlocked, and integrated friction levers hold the lid open in any position up to 95 degrees, so it stays put at whatever angle is convenient for the job at hand rather than swinging shut or needing a separate prop. The hatch is CE approved and carries a 3-year warranty. It is designed as a direct replacement flange-base hatch, so it installs into an existing Size 10 opening using the same mounting footprint.
