Low Profile Hatch - Size 20 (Flange Base)

Lewmar Low Profile Hatch — Size 20, Rectangular, 1" Flange (39920030)

A sleek, slim-profile deck hatch built for powerboats — rectangular, ideal for narrow deck or coach roof locations where a square hatch wouldn't fit.

Why It's Worth It
At just 1" tall above deck, this hatch sits much lower than Lewmar's Ocean Series, giving powerboats a cleaner deck line. Friction levers hold the lid open at any angle up to 95°, and Lewmar's sealing system makes the acrylic lens easy to replace if it's ever damaged.

Use
Installs on a flat surface with a maximum tolerance of ±1mm. Fastening at the hinge section uses M6 (1/4") hardware; the lower frame uses a 5mm CSK Screw No.10 UNC 2 BA. This size has no outside handle and can only be opened from the inside — a deliberate design choice across the smallest sizes in this line (00, 03, 10, 20, 41), so confirm that fits your intended use before ordering.
