I found a website showing a different way to install porthole screens and I thought I'd share it.

Captain Rank on Wind Rover, a CP-19, just made some screen for the ports with Velcro and soft fabric screen materal. Open and close just fine. He also made a companion way screen with Velcro.
skip.
Hi there I have a 1980-23 cp and I noticed that the ouside ports do not have a finished look,nothing but bolts. I thought they were susposed to have a rim around them. is it me or what?
