The cabin hatch definitely needs 2 supports to keep it from twisting; it's a little thin and probably won't tolerate a lot of that. Original factory configuration has velcro around inside on bottom of gutter and there is a screen with velcro that fits it. Cabin is 100% bug proof provided you seal up around where rigging comes thru next to IP on starboard side. Still need to spray the screens on hatch and cabin door to keep out the no-see-ums however.

The windshield hatch adjusters on mine have # 10-28 screws/knobs on them. My boat is outboard model, with transom closed and Hermco fiberglass bracket installed. I ended up buying a galley seat from another CSC member. Photos can be seen in link I provided, or just search for it under Photos section. I just posted it a couple of weeks ago.
