Oval Opening Boat Portlight Window 345 x 150 mm – Stainless Steel Frame

This oval opening cabin window (portlight) is designed to enhance the comfort and brightness of your boat’s interior. The hefty frame made from high-quality stainless steel ensures longevity and resistance to corrosion, even with continuous exposure to saltwater. The metal is polished to a mirror sheen, lending an elegant appearance both on the exterior hull and inside the cabin. The oval shape and low profile allow the portlight to follow the lines of the hull gracefully, without protruding or disrupting the boat’s aerodynamics.

The window pane is made of smoke-tinted acrylic glass, which is tempered for additional strength. This pane admits plenty of natural light into the cabin during the day but reduces glare and heat from direct sun, while also providing privacy. When opened, the window swings inward on sturdy hinges. On the inside, locking levers (dogs) serve a dual purpose: when the window is closed, they clamp it tight against the frame and seal; when you want ventilation, you can secure them in an intermediate position to hold the window slightly ajar without it slamming. A rubber gasket (O-ring) lines the entire frame, ensuring a watertight seal when shut – keeping rain and spray from entering the cabin.

• Light and Air: Ideal for installation on the sides of sailboats, motor yachts, or cruisers – adds natural light to cabins, galleys, or heads, and allows ventilation when needed.
• For Mid-Sized Boats: The ~345 x 150 mm size makes this portlight suitable for boats around 6–9 m in length, providing a sufficiently large opening for light while maintaining hull integrity.
• Ventilation: Can be left slightly open at anchor or in the marina to let fresh air circulate through enclosed spaces, reducing condensation and odors.
• Upgrade Appearance: Recommended for replacing old or leaky side windows – this modern stainless portlight will improve not only functionality (no leaks) but also the overall look of your boat.
