Atlantic Portlight Upper Hinge Kit

Restore Smooth, Reliable Opening for Atlantic Portlights

The Lewmar Atlantic Portlight Upper Hinge Kit is a direct-fit replacement designed for Atlantic-series portlights, Lewmar’s long-running, alloy-framed window range produced from 1994 to the present. This kit restores proper hinge function, ensuring clean, stable opening and closing of the portlight.

Engineered for Secure, Long-Lasting Performance

Built to match the original hardware specifications of the Atlantic portlight line, the hinge components provide dependable support for the acrylic lens and frame. The kit re-establishes smooth pivoting action and proper alignment, which can degrade over years of use or exposure.

Durable Marine-Grade Construction

As part of the alloy-framed Atlantic series, replacement components follow Lewmar’s marine-grade material standards, designed to resist corrosion, salt exposure, and constant mechanical load in all weather conditions. This ensures a long service life consistent with the original factory installation.

Improves Seal Pressure & Window Stability 

A functioning upper hinge helps maintain correct comparison against the portlight seal (sold separately), supporting watertight performance and preventing uneven wear on the acrylic. Restoring hinge geometry improves weather protection and the overall usability of the portlight.

Sized Specifically for Atlantic Portlights

This hinge kit is compatible only with Lewmar Atlantic-series designs, identifiable by their alloy outer frame and metal push-to-close handles. Because Atlantic portlights have remained in production since 1994, sizing is consistent and replacement parts are straightforward to install.
