Plastic access hatches for boats provide lightweight, corrosion-resistant access points for decks, galleys, and storage compartments. This guide compares five top options to help boaters choose the right hatch based on size, installation, and marine durability. Best for DIY deck updates, anglers, skippers, and boaters seeking low-maintenance, UV-resistant access points.
What to look for: material (ABS plastic for durability and UV resistance), size compatibility with your opening, a watertight seal, and ease of installation. The following table summarizes the featured products and their key strengths.

Xztrdi Round 6″ Deck Hatch
Material and construction: ABS engineering plastic offers high strength, UV resistance, heat resistance, and corrosion resistance—suitable for rainwater and seawater. Best for small boats, kayaks, or compact cockpit decks where a non-slip surface improves safety. The 6-inch hatch opening is specified as 6.3″ to 16 cm, with an outer frame of 7.75″ (19.7 cm) and inner cover of 6.41″ (16.3 cm).
Best suited for: boaters needing a compact, durable hatch with a non-slip surface for deck safety. The square convex design reduces slip risk during wet conditions. Choose this if you have a tight opening and prioritize wear resistance in sun-exposed areas.
Limitations: Installation requires that the opening diameter stays within the recommended range (6.3″ to 6.77″ opening). Non-slip pattern helps, but ensure screw alignment matches the outer frame.
CLLOMAGY Black Deck Hatch 10.63″ x 14.76″
Material and construction: Marine-grade ABS plastic, with anti-corrosion and anti-UV properties suitable for hot, cold, moist, or windy conditions. The hatch is a low-profile deck access solution designed to add storage space and improve ventilation on larger boats.
Best for: boaters needing a sizable, durable deck hatch for pontoon or yacht decks; it supports convenient storage access and ventilation. The cut size and overall dimensions fit larger deck openings.
Limitations: Cutting size and mating dimensions must be matched precisely (11.77″ x 7.89″) to ensure a proper seal and fit. Screw count and installation hardware should be confirmed before mounting.
Xpokcai 6 Inch Round Deck Plate
Material and construction: ABS round deck plate with an outer ring diameter of 7.8 inches and an inner hole of 6 inches. Includes 6 screw holes and 6 stainless steel screws for secure mounting. The design emphasizes waterproofing and UV resistance, making it suitable for boats and RVs.
Best for: hulls or cabins needing a compact inspection hatch with reliable screw-fastening and corrosion resistance. Better for installations where an all-around screw-in plate is preferred.
Limitations: Outer ring is larger than the inner hole, so precise alignment is necessary during mounting. Ensure screws are compatible with your boat’s deck material.
CROSSBODY 8″ White Round Deck Plate
Material and construction: Premium ABS with UV resistance, anti-corrosion properties, and weather-tight performance. The 8″ round hatch is designed for boats and kayaks, with a watertight O-ring seal to protect interior compartments from water ingress.
Best for: larger deck panels or storage compartments where a secure, weatherproof seal is essential. Suitable for exterior deck access and interior bilge areas that require robust sealing.
Limitations: Larger size means you’ll need a correspondingly larger cutout and proper seal installation to avoid leaks around the perimeter.
Five Oceans 6″ Round Hatch
Material and construction: UV-resistant ABS white plastic with a rubber O-ring for a watertight seal. This round hatch is designed for interior and exterior use, providing a leak-proof deck plate with a separate cover plate and chassis for straightforward installation. 6 screws are typically needed (not included).
Best for: boaters looking for a reliable 6″ round hatch that balances durability and ease of installation on bass boats, pontoons, or small yachts. The leak-proof design helps protect compartments from water intrusion.
Limitations: Screws are not included, so hardware compatibility and sizing must be planned before purchase.
Buying Guide
- What opening size do you need? Match the deck cutout precisely to the hatch’s outer frame for a proper seal and secure mounting.
- Which material best suits your boat? ABS plastic is common for corrosion resistance and UV durability, but ensure you choose a color and finish that matches your deck aesthetics.
- Do you need a non-slip surface? If so, prioritize hatches with textured or embossed surfaces to reduce accidental slips when decks are wet.
- Is waterproofing a high priority? Look for a watertight seal O-ring and a screw-in design, especially for exterior decks and hull openings.
- What installation hardware is included? Some products omit screws or require specific screw types; verify compatibility with your deck material.
- What size and shape best fit your space? Round hatches are common for small openings; rectangular hatches work well for larger panels and storage areas.
- Maintenance considerations: ABS plastics resist UV and corrosion, but regular cleaning and inspection of seals extend life and prevent leaks.
FAQ

- Q: Do I need specialized tools to install? A: Basic hand tools are usually sufficient; some models require specific screw types and cutout dimensions.
- Q: Can I use these on both interior and exterior decks? A: Yes, most ABS hatches are suitable for interior and exterior use, but verify the seal and UV resistance for exterior exposure.
- Q: Do the screws come with the hatch? A: Some include screws; others require purchasing hardware separately. Plan accordingly.
