A portlight is a porthole designed to let in light ...from the sun (or a
curious neighbor's flashlight). It's not a light fixture.

I guess your boat is trailerable? What kind of lights are you talking
about,
navigation, courtesy, etc.? If this appears no matter what, you might be
seeing "blooming" where additives in vinyl plastics come to the surface. I
kinda doubt the lenses are made of PVC though, although that's all I can
imagine. UV degradation wouldn't polish off, so you've got some sort of
contamination on the surface. Try spraying with a little Pam or silicone
spray after you clean them next time.

I have long been curious as to why the polymer lights on my boat
become cloudy relatively fast, whether near the sea or not & whether
under cover or not. It polishes off fine with a bit of work, but I
never see this occur in other acrylic or lexan windows I have around
my place, and it is a minor annoyance. Is there one particular type
of clear polymer which clouds up like this? If left for months, they
will become only translucent until repolished.

gaspOh, no! I though it's purpose was to let OUT light, so that it
stays relatively dim & romantic below...or to see OUT to starboard or
port while speed-using the head when singlehanding in crowded harbors
on autopilot. Now if it lets light IN, then I have to keep CLEANING
the main saloon, and have NO excuse for misreading charts, and will
get NERVOUS if I can see ALL those boats while trying to relieve
myself or cook, this is a very bad idea...NOW I know why they used
plastic that CLOUDS, thank God for UV degradation!
