CLLOMAGY 17.3″ x 12.4″ Marine Deck Access Hatch Lid

Best for: Small to mid-sized sailboats needing a low-profile access hatch for easier storage and ventilation. This model’s outside dimensions fit many standard deck cutouts, with an inside opening that facilitates added storage and airflow. The lid is designed for weather resistance in variable conditions, helping reduce moisture buildup in berths and cockpit lockers.
Why chosen: It combines a compact footprint with a durable ABS deck hatch lid, offering anti-corrosion and UV resistance suitable for cold, hot, or windy environments. The low-profile design minimizes snag hazards on low-clearance decks.
Caution: Verify a compatible cut-out size (14.49″ x 9.96″ recommended) to ensure a proper seal and drainage. Not ideal for unusually thick deck skins or heavy fittings near the hatch.
CLLOMAGY 17.3″ x 12.4″ Deck Hatch (Second Variant)

Best for: Sailors who want a second, similarly sized hatch option with the same dependable marine-grade lid. It serves as a practical replacement or an additional access point for better ventilation and storage on boats with multiple deck areas.
Why chosen: Mirrors the first CLLOMAGY design with a sturdy ABS shell and UV resistance, supporting consistent performance through seasons and maritime conditions. It’s a solid match for boats needing uniform hatch sizing across decks.
Caution: As with similar dimensions, ensure the cutting size matches your deck cut-out (14.49” x 9.96”). The two products are nearly identical; choose based on availability or mounting considerations on your vessel.
CLLOMAGY 24″ x 14″ Deck Hatch

Best for: Boats needing a larger hatch to improve access to deck storage and ventilation across wider deck spaces. Suitable for mid-sized sailboats and yachts with moderate hatch cut-outs.
Why chosen: This model provides a bigger opening (outer 23.86″ x 13.9″) with a correspondingly larger interior, enabling more storage and better air exchange. The ABS lid maintains marine-grade durability and UV resistance for harsher climates.
Caution: The larger footprint requires appropriate deck space and mounting clearance. Confirm compatibility with your deck’s structure before installation.
YaeMarine Square Anodized Aluminum Hatch 22.5″ x 22.5″

Best for: Sailors seeking a larger, robust hatch with a secure locking mechanism and easy access from multiple angles. The square design suits wide deck installations or cabin portals that require higher clearance.
Why chosen: Features an anodized aluminum frame for maximum corrosion resistance, a tinted acrylic window, and slip-resistant handles. The lid can be opened to broad angles, improving accessibility for loading gear or performing maintenance.
Caution: Heavier frame and hardware mean you’ll need proper mounting support and tools. Consider the extra weight for smaller vessels or retrofit projects.
Pvrud Marine Hatch Deck Cover 17.3″ x 12.4″

Best for: Sailboats and small yachts requiring a reliable, mid-sized hatch with durable framing and a simple installation.
Why chosen: Outer frame matches standard deck cut-outs, and the design emphasizes UV resistance and seawater durability through marine-grade ABS engineering plastic. The 316 stainless steel handle option enhances corrosion resistance and usability in salty air.
Caution: Verify the inner frame clearance and fastener compatibility with your deck thickness and stringers before installation.
Oceansouth Sailboat Hatch Cover 22.8″ Square

Best for: Boats needing deck hatch covers with color and fabric integration for shade and weather protection. Useful for keeping sun and rain out while maintaining ventilation.
Why chosen: Uses Sunbrella fabric over a hatch cover, offering color-fast, weather-resistant protection. Navy color blends with many boat interiors and exteriors, helping reduce glare and heat ingress.
Caution: Fabric covers can wear with heavy use; ensure proper fit to prevent wind intrusion during open hatch use.
Buying Guide: Key Considerations For Sailboat Hatches And Ports
What size hatch do I need? Start with your deck cut-out measurements and the interior access you want for storage or gear. Larger hatches provide better access but require more mounting space and may add weight.
What material is best? ABS engineering plastics offer corrosion resistance and light weight, while aluminum frames provide rugged strength for larger applications. UV resistance and weather sealing are essential for longevity at sea.
Is a locking mechanism important? Yes for safety and security in rough seas or when unattended. Look for secure latching and optional anti-slip handles for easier operation with wet gloves.
Do I need a window? Some hatches include tinted acrylic windows for visibility and light. If you want maximum ventilation, ensure the design allows ample opening range without interference from surrounding equipment.
How easy is installation? Verify cut-out dimensions, interior dimensions, and the hatch’s compatibility with your deck thickness and structure. One-person installation is possible for certain models with simple mounting patterns.
Frequently Asked Questions
- What is the typical cut-out size for standard sailboat deck hatches? Many common mid-sized hatches use cutting sizes around 14.5″ x 9.9″ or 21.0″ x 11.4″; always measure your deck first.
- Are aluminum hatches worth it on saltwater boats? Aluminum offers strength and corrosion resistance, especially for larger hatches, but weight and cost are higher than plastic options.
- Can hatch covers improve cabin ventilation? Yes; larger openings and properly positioned vents help move air through berths, heads, and galleys, reducing moisture buildup.
- Do hatch lids need seals? Seals help prevent water intrusion and heat transfer, preserving interior comfort and gear.
- Is a UV-resistant hatch necessary? Yes, UV resistance prolongs the life of plastic components exposed to sun and heat, reducing cracking and color fading.
- Which hatch is best for a small sailboat? For compact decks, a 17.3″ x 12.4″ hatch with a low-profile lid is often ideal, balancing ventilation with footprint.
