Lewmar's Ultra-Low Profile Hatch

Lewmar's Ultra-Low Profile Hatch is engineered for superior ventilation and sleek marine performance, featuring a 360° vent position that ensures optimal airflow throughout the vessel for comfort and freshness. The hatch offers versatile options, including flush bi-square lids for a seamless deck appearance or external handles for convenience and compliance with marine regulations. Its self-supporting friction lever mechanism securely holds the hatch at any angle, while the lightweight grey acrylic lid provides durability without adding bulk, sitting just 10mm above the deck for an unobtrusive, streamlined profile. The silver-anodized lower frame offers excellent corrosion resistance in harsh marine environments, ensuring long-lasting performance. Designed for easy retrofitting, the cut-out aligns with Lewmar Low Profile, Medium Profile, and Ocean Hatches, as well as select other brands, allowing installation without modifications or additional deck drainage holes. Compatible with existing trims and flyscreens, this hatch provides practical functionality and cost-effective upgrades for boat owners seeking reliable ventilation, durability, and a low-profile design.
