Oval Fixed Portlight (Stainless Frame, 130 x 400 mm Outer)

This oval fixed portlight (also known as a “deadlight”) is designed to illuminate your boat’s interior while maintaining complete watertight integrity. Its frame is made of highly polished stainless steel, which not only looks elegant on the hull but also ensures durability in the marine environment – it will not rust or tarnish over time. The design is non-opening (fixed), meaning once installed the window remains permanently sealed. This eliminates any risk of water ingress even in heavy seas or downpours, while still allowing plenty of sunlight to stream into the cabin.

The portlight features a robust clear acrylic pane of a thickness suitable for marine use. The acrylic is specifically chosen for its resistance to ultraviolet radiation – it will not yellow or become brittle under sunlight, preserving excellent visibility and light transmission. Additionally, the acrylic lens is impact-resistant and scratch-resistant, ensuring long-lasting performance. The outer frame dimensions are 130 x 400 mm, with a recommended cutout of about 115 x 388 mm, which aligns with standard sizes for this type of oval window. Installation is done using bolts/screws (typically fastened from the inside) and a proper marine sealant to achieve a watertight bond to the hull. Once correctly installed, the portlight requires minimal maintenance – simply clean the glass and frame occasionally with an appropriate cleaner. This oval portlight is commonly installed on the sides of cabins, saloon areas, or heads (bathrooms) of yachts and boats, where it adds pleasant natural light and lends a classic nautical appearance.

• Use Case: Suitable for mounting on the hull sides or cabin superstructure of sailing and motor yachts – for example, as side windows in the cabin, galley, or head. It can also be used as a decorative fixed window on interior bulkheads
• Installation: Requires a precisely cut opening in the hull. It’s recommended to install with a high-quality marine sealant (silicone/polyurethane) and stainless steel fasteners. An interior trim ring (if provided) will cover the screws and give a finished look inside
• Advantages: Provides daylight below deck, reducing the need for artificial lighting during daytime. The fixed design means there are no moving parts or hinges to service – once installed, the window remains reliably sealed without adjustments
• Compatibility: The standard size and shape make it a suitable replacement when refitting old portlights or upgrading your boat. The stainless steel and acrylic construction complements both classic and modern yacht designs
