Bomar Hatches

Bomar Hatches: The Benchmark in Marine Deck Hardware

When boatbuilders and serious offshore sailors specify a deck hatch, Bomar is one of the first names they reach for — and for good reason. As the world's largest producer of aluminum hatches, both cast and extruded, Bomar makes more than 90 percent of all powerboat hatches and has long held an equally respected position in the sailboat market. That kind of market presence doesn't happen by accident; it's the result of decades of purposeful engineering and an obsession with material quality.

A Complete Range of Hatch Styles and Series

Browse the full Hatches category and you'll quickly appreciate the breadth of Bomar's lineup. From flush-mount styles to heavy-duty cast and sliding options, Bomar offers a complete range of commercial-grade deck hatches engineered for strength, security, and all-weather performance. Key series include:

• 900 Series (Molded Low Profile): The 900 Series features quick-action dogs, vent positioning, a smoke acrylic lens, and a collet arm, with trim ring and screen options available. Available in black or white, these molded hatches are a popular drop-in replacement for older, leaky units.
• 1000 Series (Extruded Low Profile): The 1000 Series offers extruded aluminum construction with secure twist-and-dog systems for optimal sealing. The external A-hinge design keeps the hinge hardware out of the opening plane for a clean look.
• 2000 Series (Hi-Profile Extruded): The 2000 Series deck hatch is known for its low-profile design that enhances the aerodynamics and aesthetics of a boat, and features a flush mount, stainless steel latch, and an integrated screen and trim ring.
• 7000 Series (Low Profile Access): A rectangular, bright-white access hatch designed for cabin top and deck applications where a wide opening is needed.
• 8000 Series (Low Profile Inspection): These flush-mounting, molded low-profile hatches are fully gasketed with UV-stabilized resin and a non-skid surface, and come with "T" handles for easy operation and stainless steel hinge pins.
• 100 Series (Cast Aluminum): Bomar 100 Series cast hatches are built to last, featuring durable Almag-35 cast aluminum construction and stainless steel hardware.
• SS Voyager (Stainless Steel): The Bomar SS Voyager hatch features robust stainless steel construction and a sleek, low-profile design, incorporating a secure dog system and reliable hatch gasket to provide an excellent seal and prevent water ingress.

What Sets Bomar Hatches Apart

Material selection is central to Bomar's reputation. Marine-grade aluminum, stainless steel, and impact-resistant acrylics — every material Bomar uses is chosen for long-term performance and minimal maintenance. The low-profile aluminum series in particular is engineered to address a real safety concern on deck: high-impact acrylic lenses and smooth edges eliminate sharp corners that could snag lines or sails.

Bomar also understands that no two boats are alike. The company offers modifications, custom sizing, and integration with deck camber specs, tread plates, and more. Manufactured in the USA and trusted by commercial boatbuilders worldwide, Bomar hatches are backed by a legacy of performance and support.

For owners maintaining existing hardware, Bomar replacement parts are readily available, ensuring long-term performance and maintenance ease. The Bomar hatch riser arm, for example, is a key mechanical component that holds the hatch open at various angles, providing controlled ventilation while preventing the lid from slamming shut due to wind or wave action.

Choosing the Right Bomar Hatch

The sleekly designed low-profile hatch is ideal for use on a powerboat, while smaller ventilation hatches are a better fit for sailboats, and the larger sizes can be used as foredeck hatches on smaller to mid-size yachts. Whether you're upgrading a cruising sailboat, refitting a sportfisher, or outfitting a new build, Bomar's extensive series lineup ensures there is a hatch engineered for your specific application, deck thickness, and aesthetic requirements.
