Lewmar 360867999 Replacement Seal — Low Profile Hatch Series
A replacement seal for Lewmar Low Profile hatches — one of the most widely installed deck hatch series on production sailboats and powerboats. This seal fits into the hatch frame channel to create a reliable compression seal between the frame and the acrylic lens, preventing water intrusion into the cabin below.
Hatch seals are a wear item. UV exposure, compression set, and repeated opening and closing cycles cause the rubber to harden, flatten, and lose its sealing ability over time. Replacing the seal is a straightforward repair that restores full weathertight performance without replacing the entire hatch assembly.

Parts Desk Insights
Lewmar offers more than one seal part number for the Low Profile series — confirm your specific hatch model and seal channel dimensions before ordering to ensure you select the correct seal. If you’re unsure which seal your hatch requires, cross-reference your hatch’s documentation or compare with the alternate Low Profile seal, the Lewmar 360872999 Low Profile Hatch Seal. Confirm you have a Low Profile hatch (not Medium Profile or Ocean series) before ordering — the series name is typically molded into the hatch frame. For the hatches themselves, see the Lewmar Low Profile Rectangular Hatch Size 03, Size 20, Size 40, Size 50, Size 60, or the Lewmar Low Profile Round Hatch Size 22. SKU: 239-360867999.
