Product details
The Ultra Low Profile Hatches from LEWMAR have been specifically designed for demanding applications on board. With only 10 mm of height above the deck, they impress with a nearly flush, sleek design that not only looks appealing but also offers functional advantages on the boat. The reduced height minimises wind resistance, protects against tripping hazards, and emphasizes the clear, timeless appearance of modern watercraft in both professional and sport contexts.
Made from robust grey acrylic glass, the Ultra Low Profile hatch brings an excellent balance between durability and lightweight design. Its self-supporting design with friction lever mechanism holds the hatch securely at different opening angles - ideal for flexible ventilation on the high seas. The hatches also feature a 360° ventilation position, which enables continuous air circulation in the interior of the boat.
The Ultra Low Profile hatch is also ideal for retrofitting. It is fully compatible with existing panelling and flyscreens and in addition the hatches have the same cut-out design as the Lewmar Low Profile, Medium Profile and Ocean hatches. This means it can be easily fitted into existing cut-outs without additional drainage holes or conversions.
The version with the external handles ensures additional user-friendliness and compliance with technical regulations.
