Custom Hatches by Cule Marine
Engineered to fit your vessel exactly — not the other way around.
Two decades of custom craft
Every vessel is different — and so are the demands placed on the hatches that keep it safe, dry, and functional. While Cule offers a core range of standard hatch sizes, a large part of our work is designing and manufacturing custom hatches for OEM boatbuilders, refit specialists, and owners who need something built specifically for their project.
Our team has been manufacturing marine hatches in West Auckland since 2007, and custom work has always been at the heart of what we do. Whether you're matching an existing aperture, solving a tricky design challenge, or creating a signature look for a new model launch, we can engineer a hatch that fits your vessel perfectly.
Built for your boat — not the other way around
A custom hatch isn’t only about changing the size. It’s an opportunity to tailor key details to suit your vessel and build.
Exact dimensions to suit new builds or legacy cutouts
Unique shapes including trapezoids, curves, and non-standard geometries
Custom corner radii to match existing deck cutouts
Material and finish options including frame colour and acrylic choices
Hardware choices such as gas struts and and locking systems
OEM branding and production consistency for multi-boat runs
If you’re designing a new model or refreshing an existing one, we can work directly with you to ensure the hatch integrates cleanly with your vessel structure and aesthetic.
Made in West Auckland
Precision manufacturing, made in New Zealand
All Cule hatches — standard and custom — are manufactured locally in West Auckland using premium 6063 alloy and marine-grade components. Our process combines CNC accuracy with hand-finished detailing, giving you a hatch that's both robust and refined.
Because everything is produced in-house, we can maintain tight control over quality, lead times, and repeatability — essential for OEM builders who need consistency across multiple vessels.
When custom makes sense
If you're unsure whether your project needs a custom hatch or a modified standard model, we can advise you on the most efficient and cost-effective path.
Custom hatches are ideal for:
New boat designs where standard sizes don't fit the layout
Refits and restorations with legacy cutouts or unusual openings
Commercial vessels requiring specialised access points
Architectural or superyacht projects where aesthetics drive the design
Situations where safety, drainage, or clearance require a specific geometry
Simple and collaborative
