Medium Profile Hatch Acrylic & Seal MK3

Restore Clarity and Watertight Performance to MK3 Medium Profile Hatches

The Lewmar Medium Profile Hatch Acrylic & Seal MK3 is a genuine replacement assembly designed specifically for Lewmar’s Medium Profile Hatch Acrylic & Seal MK3 hatch range. It refreshes the hatch’s appearance while restoring full watertight protection and smooth, dependable operation.

Durable, UV-Resistant Acrylic Panel

Each replacement lens is manufactured from high-quality marine-grade acrylic, engineered to resist UV damage, saltwater exposure, and surface crazing. This delivers long-lasting optical clarity and a clean, modern look, instantly improving natural cabin light and visibility.

Pre-Mounted Seal for a Factory-Tight Closure

Like other Lewmar acrylic replacement kits, the MK3 variant includes a new gasket already fitted to the panel. This ensures perfect compression against the hatch frame and restores leak-free performance, helping to prevent moisture intrusion, drafts, and rattling.

Smooth and Reliable Hatch Function

A fresh acrylic and seal combination helps maintain proper interface with the hatch hinges, handles, and friction mechanisms. This improves the ease of opening and closing while preserving even seal pressure around the entire frame.

Designed for Direct Fit on MK3 Medium Profile Models

As an official Lewmar spare, the MK3 Acrylic & Seal kit is precision-cut and shaped to match the original medium-profile hatch geometry. It installs cleanly into the existing upper frame without modification, making it ideal for refits or routine maintenance.
