Overview

The Lewmar Ultra Low Profile Hatch Size 41 is a durable and lightweight marine hatch, sitting only 10mm above the deck. It features a grey acrylic lid and an anodized aluminum lower frame for corrosion resistance. Designed for easy retrofitting, it is compatible with existing Lewmar Low Profile, Medium Profile, and Ocean Hatch installations, as well as existing Lewmar trims and flyscreens. The new hinge system allows the lid to open up to 90 degrees and offers a 360-degree vent position. It is CE approved and patent pending.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
