Oceansouth Low-Medium Profile Hatch Covers
The Oceansouth low-medium profile hatch covers are crafted from Atlas Marine Canvas (9.14 oz/yd²) and feature a drawstring surround. They are breathable, helping reduce condensation and offering strong UV protection. Best for boaters needing a lighter, easily adjustable cover for mid-sized Lewmar hatches. Avoid this if you require a high-profile or extra-wide cover for very large openings.
CLLOMAGY White Deck Hatch Lid
This marine deck hatch lid is built for a 14.76″ x 10.63″ exterior opening. Made from ABS plastic, it emphasizes corrosion resistance and UV protection. It adds storage space and enhances ventilation, making it suitable for bass boats, John boats, and small sailboats. The limitation is that it suits specific exterior dimensions, so sizing is crucial for a proper seal.
CLLOMAGY 17.3″ x 12.4″ Hatch Deck Lid
For medium hatch openings, this lid provides a reliable ABS plastic option with robust anti-corrosion and UV resistance. It supports added storage and improved ventilation, catering to fishing or sailing setups. Choose this size if your deck hatch is near the 17″ by 12″ range; if your hatch is larger or smaller, look for a closer match to avoid gaps.
Oceansouth High Profile Hatch Covers
These high-profile hatch covers, also in Lewmar sizing, are made with Atlas marine fabric for durability. The drawstring surround seals well and reduces moisture buildup while offering superior UV protection. Best for larger hatch openings or when a higher cover is needed to reduce heat transfer. A potential limitation is that the higher profile may be bulkier to store in tight spaces.
Oceansouth Square Sailboat Hatch Cover
Designed for sailboats with square hatches, this cover emphasizes UV protection and weather resistance. It uses heavy-duty Atlas marine fabric designed for long outdoor use, reducing direct sunlight and heat entry beneath the deck. Best for sailboats moored in sunny climates; consider alternatives if you need a rectangular fit for certain hatch shapes.
Buying Guide
What size should I choose?
Match the exterior hatch dimensions to avoid gaps. If in doubt, measure length and width at the widest points and compare to the listed outside dimensions. Some lids allow minor overhang for better sealing.
What material matters most?
Atlas marine fabric offers UV resistance and durability for long outdoor exposure. ABS plastic lids provide rigid structure and corrosion resistance, useful for frequent hatch use. Consider climate: UV-heavy regions benefit from UV-protective materials; humid regions benefit from breathable fabrics to reduce condensation.
What features improve longevity?
Breathable canvas helps condensation control. Drawstring surrounds enhance a snug fit. Non-slip surfaces and weatherproof seals prevent moisture ingress around the hinge area.
Are these covers universal for all hatch brands?
Some are designed for Lewmar hatches or specific exterior sizes. Always verify compatibility with your hatch brand, opening size, and mounting pattern before purchase.
How does installation differ between covers?
ABS lids often require simple push-in or screw-in mounting, while fabric covers with drawstrings require threading through the hatch frame and securing the drawstring for a tight seal. Check for included hardware and follow the manufacturer instructions.
FAQ
- Q: Will these covers prevent heat from entering my cabin?
- A: High-profile and UV-protective covers reduce direct sunlight, helping lower cabin heat in hot weather.
- Q: Are the covers waterproof?
- A: Most lids provide water resistance and seal around the hatch, but they are not submariner-grade waterproof. Check for weatherproof seals and drain designs.
- Q: Can these covers be used on RV or camper hatch doors?
- A: Some lids are compatible with RV deck hatch openings; verify dimensions and mounting suitability for non-boat use.
- Q: Do covers require special storage when not in use?
