Round Boat Hatches
Our Round Aluminum Deck Hatches are premium-quality access solutions designed to provide natural light, ventilation, and secure entry points on a wide variety of vessels. Precision-machined from corrosion-resistant anodized aluminum alloy, these round hatches are built to withstand the harsh marine environment while maintaining a sleek, low-profile appearance.
Featuring a durable dark smoke acrylic (PMMA) lens, these hatches offer exceptional toughness and impact resistance compared to traditional glass. The acrylic material is environmentally friendly, provides soft, diffused light transmission, and ensures clear vision without the risk of shattering. Designed for ocean-going vessels, the low-profile frame minimizes wind resistance and complements modern boat aesthetics.
A key safety feature is the red locking button, which provides an intuitive child-safe or security lock. Turning the button to the left locks the hatch, preventing it from being opened from the outside. Turning it to the right unlocks it, allowing operation from both inside and outside the vessel.
Certified with CE approval, these versatile round hatches are suitable for installation on boats, yachts, ships, and even RVs (recreational vehicles) . Available in five standard sizes with cut-out dimensions ranging from 278mm to 522mm, they are the ideal choice for builders and owners seeking a combination of durability, safety, and style.
Key Features & Benefits
-
✅ Corrosion-Resistant Anodized Aluminum Frame: The frame is constructed from marine-grade aluminum alloy and finished with an anodizing process, creating a hard, protective surface that resists saltwater corrosion and UV degradation.
-
✅ Tough Acrylic (PMMA) Lens: The dark smoke acrylic lens is highly impact-resistant, durable, and will not shatter like glass. It filters harsh sunlight, providing soft interior lighting while maintaining excellent outward visibility.
-
✅ Secure Red Button Locking System: Features an intuitive red button mechanism:
-
Turn Left: Locks the hatch, preventing external opening (ideal for security when the vessel is unattended).
-
Turn Right: Unlocks the hatch, allowing it to be opened from both inside and outside.
-
-
✅ Low-Profile Design: The streamlined frame sits flush with the deck, reducing wind resistance and creating a clean, modern look suitable for performance vessels.
-
✅ CE Certified: Manufactured and tested to meet European safety and quality standards, ensuring reliable performance.
-
✅ Multiple Size Options: Available in five sizes to suit various applications, from small compartments to main cabin skylights.
-
✅ Versatile Application: Perfect for marine use (boats, yachts, ships) and also suitable for land-based vehicles like RVs and campervans.
-
✅ Lightweight Construction: The aluminum and acrylic combination results in a lightweight unit (from 2.70kg to 6.25kg) that is easy to handle and install.

Frequently Asked Questions (FAQ)
1. What is the advantage of an anodized aluminum frame over a painted frame?
Anodizing is an electrochemical process that converts the metal surface into a durable, corrosion-resistant, anodic oxide finish. Unlike paint, which sits on top of the metal and can chip or peel, the anodized layer is integral to the aluminum. This provides superior protection against saltwater corrosion, is harder than paint, and is more resistant to UV fading, making it the ideal choice for a marine deck hatch.
2. Why is acrylic (PMMA) used instead of glass for these hatches?
Acrylic offers several key advantages for marine applications:
-
Impact Resistance: Acrylic is significantly stronger and more impact-resistant than standard glass and will not shatter into sharp, dangerous shards upon impact.
-
Lightweight: It is approximately half the weight of glass, contributing to the hatch’s low overall weight.
-
UV Resistance: High-quality acrylic like PMMA is formulated to resist yellowing and degradation from long-term sun exposure.
-
Clarity: It provides excellent optical clarity, and the dark smoke tint reduces glare and heat buildup inside the vessel.
3. How does the red button locking mechanism work for security?
The red button acts as a simple but effective lock.
-
When you turn the button to the left (counter-clockwise) , it engages a lock that prevents the opening handle from being operated from the outside. This is useful when you leave your boat to prevent unauthorized entry.
-
When you turn the button to the right (clockwise) , it disengages the lock, allowing the hatch to be opened normally from both the inside and the outside. This provides flexible access while maintaining a simple, child-proof style lock.
4. What does “Cut-out Dimensions” mean, and how do I use it for installation?
The Cut-out Dimension is the most critical measurement for installation. It is the size of the hole you must cut in your deck or cabin top to correctly fit the hatch frame. You should mark this dimension (e.g., a 278mm diameter circle for item 0094AA28) on your deck surface and cut the opening carefully. The hatch’s external flange (External Dimension) will cover the cut edge and provide the sealing surface.
5. Can the frame be supplied in a color other than silver?
Yes. While the standard anodized finish is a natural silver/gray color, we offer customization options. The frame can be made in black upon request. For larger orders, we may be able to accommodate other colors or custom anodized finishes. Please specify your color preference when inquiring or placing an order.
