Smartmarine White Round Hatch Series
These round access hatches come in 4″, 6″, and 8″ sizes with a detachable cover and a non-slip surface. Crafted from solid ABS, they are weather-tight and sealed with an O-ring. UV resistance and anti-corrosion properties help them withstand sun, spray, and salt air. The 180° opening feature makes interior access easier from the deck, while a reinforced design supports safe footing on wet surfaces.
Best for: Small boats and yachts needing a compact hatch that still provides reliable weather sealing. Choose this set if you want flexibility in deck layout and a non-slip top surface for safety.
Caution: Ensure the cutout size on the deck matches the hatch diameter to avoid gaps that can compromise weatherproofing.
Smartmarine 6-Inch Round Hatch
Designed as a mid-size option, this 6″ round hatch emphasizes a smooth, non-slip surface with a heavy-duty ABS body. It features a weather-tight seal and 180° opening, enabling easy access to bilge compartments, crew storage, or ventilation channels. Its universal appeal lies in interior and exterior applications across a range of boats and yachts.
Best for: Boats that need more generous access without sacrificing deck integrity. It’s a strong general-purpose hatch for mid-sized vessels.
Caution: The 6″ size may require a precise mounting hole and gasket fit; plan for a snug, sealed installation to maintain weatherproofing.
CLLOMAGY White Deck Hatch 10.63” x 14.76”
This larger rectangular hatch provides a robust deck access solution with a low-profile design that adds storage opportunities and improved ventilation. The interior and exterior surfaces are made from durable ABS plastic with anti-corrosion and anti-UV properties, suitable for exposure to extreme weather and vibration. Cutting size is designed to fit specific deck footprints, ensuring a clean, professional install.
Best for: Boats and RVs where a larger access hatch is needed for storage, ventilation, or equipment access on the deck. Choose this if you want more headroom and airflow.
Caution: Confirm the cutout dimensions precisely to ensure a seamless fit and proper seal around the perimeter.
CLLOMAGY Black Deck Hatch, 14.76” x 10.63”
This black variant preserves the same measurements as the white version and adds a darker, low-visibility profile for certain boat aesthetics. It’s built with a durable ABS deck hatch lid that resists corrosion and UV exposure while offering reliable ventilation and storage potential. The hatch is a practical choice for bass boats, sailboats, and mid-sized yachts where color-coordination matters.
Best for: Visibility-conscious installations or boats that prefer a darker deck hatch. It’s the better choice when you want a consistent look with a black deck or hull.
Caution: Lighter interiors may show scratches more readily; handle with care during installation to preserve appearance.

This kit includes 4″, 6″, and 8″ round deck plates with detachable covers, designed for ships, RVs, and outdoor facilities. Made of UV-resistant ABS, the deck plates are corrosion-resistant and durable.

Best for: DIY installations where multiple hatch sizes are needed for a flexible deck plan or for retrofit projects on boats with varying deck thickness or cutouts.
Caution: Verify screw compatibility and mounting hole patterns before purchasing multiple sizes to avoid mismatches during installation.
Buying Guide: Small Boat Hatch Essentials
What size should I choose?
Measure your deck cutout precisely. Round hatches fit smaller openings (4″ to 8″), while rectangular hatches like 10.63″ x 14.76″ suit larger decks. The size choice affects ventilation, storage capacity, and installation complexity.
What material and seals matter?
Most marine hatch lids use ABS plastic for durability and UV resistance. Look for O-ring seals and UV inhibitors to ensure weatherproofing against rain, spray, and sun exposure. A non-slip surface on the lid improves safety when the deck is wet.
Internal vs. external applications
Hatches designed for interior and exterior use perform well in both environments. Consider whether you need a low-profile lid for a flush deck or a protruding lid for easier removal and grip.
Ventilation vs. storage balance
Deeper or larger hatches tend to provide more storage space and greater ventilation opportunities. If ventilation is the priority (for fishing boats or engine compartments), choose a hatch that emphasizes airflow along with access.
Installation considerations
Check mounting hole patterns, cutout dimensions, and gasket compatibility. Ensure a proper seal with the correct screws and mounting hardware. A detachable cover can simplify cleaning and maintenance but may require additional hardware to stay secure in rough seas.
Which hatch to choose for your boat type?
- Small boats or kayaks: 4″ to 6″ round hatches with non-slip surfaces are most practical.
- Medium boats and bass boats: 6″ round or 10.63″ x 14.76″ rectangular hatches offer a balance of access and storage.
- Yachts and larger decks: Larger rectangular hatch lids provide more ventilation and storage access, while color choices like black can match deck aesthetics.
