I have Hunter 38 2008 and just replaced all of my screens this year.
it does depend on whether you have what the refer to as the old style ports or the new style ports.
Defender had the best pricing. And they have pictures of the ports to help you determine if old or new style. My 2008 has new style.
There are four of the larger ones that that are a size 3 and the screen size is 17 11/16 by 7 5/8 inch
and there are four smaller ones including aft cabin, on the boat that are size 1 and they are 12 1/4 by 5 1/2
Do yourself a favor and buy the better screens that have two vertical bars that fit in the ports with a retainer clip. They are more expensive BUT they actually stay in. The original style screens are almost what I’d call disposable. A good wind will take them out, look at them wrong and they fall out, and they DO NOT float so they are gone.
I replaced the originals years ago after so many fell out. Went to the upgraded screens and this is my first time replacing them and it’s only because of sunlight degradation. Not because they fell out and overboard.
