what does that little plastic white vent go to?its near the bow eye?

I have wondered the same thing.

on my 42 it drains the Anchor locker....BZ

that makes sence but i don't have an anchor locker.

My 35 Ex has one too (no anchor locker)...my guess is it's a drain for the void where the anchor locker would be! Someone will know, have to wait and hear from the right person!

It is to equalize the atmosphere in that small sealed chamber behind the mirror to fight condensation that would accumulate if it were not vented . kind of like turning a glass upside down in the sun water droplets form on the inside from humidity and temp differential. My old 35 did not have one and it was like a greenhouse sometimes when I replaced my bow lights
I drilled a vent into the cabin and the problem was solved..

See, told ya'!

thanks BOB

So thats what it is. I guess I could plug it and grow flowers or mold.
Thanks. Mystery solved.
