Oceansouth Custom Low-Medium Profile Hatch Covers for Lewmar – Blue
The Lewmar-specific blue hatch cover uses high-quality 9.14 oz/yd² Atlas Marine Canvas. It features a yacht-flush surround with a drawstring, creating a breathable membrane that reduces condensation and offers strong UV protection. Best for boaters with Lewmar low-medium profile hatches who prioritize a tailored, secure fit and UV resistance. Caution: color may fade with prolonged sun exposure; confirm exact hatch dimensions before ordering.
Oceansouth Custom Low-Medium Profile Hatch Covers for Lewmar – Sand
Designed for LEWMAR Low-Medium Profile Hatches, this sand-colored cover uses the same durable 9.14 oz/yd² ATLAS Marine Grade Fabric. It offers a secure elasticized hem that helps keep the cover taut whether the hatch is open or closed. Best for smaller Lewmar hatches on coastal cruisers or daysailers. Limitation: fit relies on the elastic hem; if the hatch dimension slightly differs, a tighter seal may require adjustment.
Oceansouth Sailboat Hatch Cover Square 22.8″ L by 22.8″ W
Square hatch covers use Sunbrella 100% solution-dyed acrylic for durability and colorfastness, with a surround drawstring and a Sure-lock toggle for secure closure. Navy blue color provides a classic, professional look. Best for boats with square hatch openings where robust weatherproofing is needed. Caution: Sunbrella fabric offers excellent UV resistance but may require occasional cleaning to maintain breathability.
Oceansouth Sailboat Hatch Cover Round 23.6″ Diameter
Round hatch protection with Sunbrella fabric delivers weather resistance and color stability. The surround drawstring and Sure-lock toggle keep the cover secure, while navy color maintains a clean deck appearance. Best for round hatch openings on mid-to-large sailboats. Limitation: round covers may require precise diameter measurement to ensure a snug fit; verify hatch diameter before purchasing.
Smart Marine 6 Inch Boat Hatch Cover
Crafted from solid ABS with an O-ring seal, this hatch cover is weather-tight and UV-resistant. Suitable for various boats and decks, including interior and exterior applications. Best for small deck plates that require a non-slip surface and a reinforced build. Caution: small hatch openings may limit use to 4″, 6″, or 8″ sizes; confirm compatibility with your deck plate.
Buying Guide
Key considerations for fabric hatch covers include hatch profile compatibility, material durability, ventilation, and ease of installation. Matching the hatch type—square, round, flush, or low-medium profile—ensures a proper seal and reduced condensation. Breathable fabrics like Atlas Marine Canvas or Sunbrella offer UV protection and moisture management, while elasticized hems or drawstrings help maintain a secure fit in shifting seas. For navigation-heavy routes or high-spray conditions, prioritize covers with stronger seals and tighter fits.
Frequently Asked Questions
- What hatch cover material lasts the longest in marine conditions? Sunbrella and Atlas Marine Canvas are designed for marine use, offering durability and UV resistance, though regular cleaning helps maintain breathability.
- How do I know which hatch cover size to buy? Measure hatch opening length and width (or diameter for round hatches). Choose a cover that matches or slightly exceeds these measurements for a snug fit.
- Are these covers waterproof? Most covers are water-resistant and breathable, designed to reduce moisture buildup; none guarantee complete waterproofing in extreme conditions without additional seals.
- Can I install these covers myself? Yes. Most use drawstrings, elastic hems, or toggles and do not require tools. Follow manufacturer-supplied installation guidance for best results.
- Which cover is best for a round hatch? Round hatch covers, such as the 23.6″ diameter Oceansouth option, are specifically shaped for round openings and minimize gaps when properly sized.
- Do these covers affect hatch operation? When properly fitted, covers should not hinder opening or closing; ensure the cover sits clear of hinge zones and locking mechanisms.
