Features:

Classic, Robust Alloy-Framed Portlight for Long-Term Marine Performance

The Lewmar Atlantic Portlight is a durable, premium grade portlight design used on thousands of productions and custom yachts since 1994. Featuring a strong alloy frame with a bonded acrylic pane, it delivers dependable ventilation, excellent visibility, and long service life in demanding marine conditions.

Alloy Frame with Metal Push-to-Close Handles

The Atlantic series is defined by its anodised alloy outer frame and metal push-button handles, providing a secure, positive closure every time. This robust hardware ensures smooth operation and long-term reliability, even with frequent use and heavy weather exposure.

Marine-Grade Acrylic for Clear Visibility

Each Atlantic portlight uses a high-quality acrylic lens designed to resist UV damage, saltwater exposure, and impact. This keeps visibility clear and reduces the yellowing or crazing common in older portlights, making it a popular choice for refits and restorations.

Reliable Weather Protection & Ventilation

The portlight provides excellent airflow when open and secure sealing when shut. When paired with a fresh Atlantic-series seal, it protects your cabin from leaks, drafts, and spray while maintaining smooth, rattle-free operation.

Fits a Wide Range of Boats Since 1994

Designed and produced continuously from 1994 to the present, the Atlantic Portlight remains a widely used solution on many sailing and motor yachts. Replacement parts, including acrylics, seals, hinge kits, and flyscreens, are readily available making ongoing maintenance simple.
