Oval Porthole Window 470x210mm Inward Opening Portlight for Yacht, Waterproof

Meet the DOACT Oval Opening Portlight Window, a 470x210mm inward-opening porthole crafted for marine and RV use. The oval design invites more natural light into the cabin, brightening spaces while providing reliable ventilation on long passages. Built to endure harsh marine conditions, this window combines a sturdy ABS frame, corrosion-resistant stainless steel hardware, and thick tempered glass for lasting durability against impact, aging, and exposure. Fully sealed and waterproof, it features an insect screen, locking fixing handles, and a robust outer frame that prevents rainwater from entering. The opening mechanism offers 0–180° adjustment with a switch lock handle and a support rod, giving you flexible airflow and an unobstructed view whether you’re cruising or parked at anchor. The inward-opening configuration is mounted with the fixed frame outside the cabin and the glass surface inside, making it suitable for boats, yachts, ships, and RVs. Note: installation is slightly more difficult; we recommend consulting a professional engineer to ensure a precise, leak-free fit.
