The Atlantic Portlight has clean styling and a clear view through the window.
Its strongly built aluminum outer frame is heavier than Lewmar's Standard Portlight, with just one welded joint.
The 5/16" thick, smoke gray, acrylic lens is bonded to its own aluminum frame for additional stiffness.
The portlight has quick-action metal handles and friction hinges, so it's easy to operate and stays where you leave it.
The interior side is very clean looking, with an anodized aluminum frame and lens trim.

External frame is designed to drain water, even when angled, thus preventing water from entering the boat when opened
Friction hinges allow for any open position without the need for knobs, stays or straps
Quick action metal handles apply correct pressure evenly on the seal, with no need for adjustment
Comes complete with insect screen and aluminum inside trim
Easy to install; cut-out shapes are simple
Spigots (the part that inserts into the hull) for thinner (8-15 mm/0.31-0.59") and thicker (16-24 mm/0.63-0.94") hulls are available; inquire if you don't see what you need
Note - Portlight opening can be restricted on very thick hulls; at 24mm portlight opening angle is 115
Note - Unlike the photo, size 32 has a larger corner radius and has semi-circular, rounded ends with no straight section
