Vision 32 side ports?

Hi All,
My first post here. A couple of years ago I bought a Vision 32. After decades of owning sail boats I had decided I was done, but after a couple years I got the urge for something simple. I stumbled across this. About twenty years ago I knew somebody that had one. I never sailed on it, but I know he loved it. I did have a couple of friends with Freedom 35s and I always liked them. This looked interesting, and the money was small enough to not feel guilty when I wasn’t using it. I have come love this thing. Once I got the 16’ of birds nests etc out of the boom, replaced reefing and other lines, sorted out the roller furled and some other things, it sails great and is easy to handle. It also handles nicely under power, the interior is terrific, oh and my wife loves that electric winch.

Anyway, I do have a bit of an issue with the side frameless fixed ports, the big ones, “15 x 7’. They are held on with 6 screws, 3 top and 3 bottom, spaced about 30” apart. They had some leaks when I bought it. I removed them, cleaned them, and put back with fresh butyl. The issue is, because they are so big, things move, then start to leak a bit. When they do, I get out some butyl and massage it into the problem spot. That fixes it until next time.

I’ve never owned a boat with big fixed frameless ports like this. Has anyone else had an issue? How did you deal with it? I’m considering drilling and adding two more screws to the top, splitting the 30” to 15. Any thoughts?
Thanks

Scroll down to the "Surface Mounted" section .. DIY: Replacing Fixed Portlights - Sail Magazine
The thick 3M VHB tape is a great thing that allows for movement of the plexi, and it is closed cell, meaning that water won't leak through.. Priming the plexi (3m Primer 94) and the cabin mounting area is important as well as meticulous prep prior to priming.. I did caulk the edges with Dow 795 after sticking them with the VHB. My one piece, now surface mounted plexi is 8" by 64" .. so far has gone through the heat of one summer and Hurricane Ida with no leaks.
Welcome to the forum !
Watch this video .. this guy does a good job of show and tell, but he did not use primer, mostly because of the small size of the plexi.. and that the glass is flat..

Thank you sail sfbay and kloudie1, good information. When I redid it I used butyl tape not VHB tape. I‘m still thinking when I do it again I may add two more screws just to help all that big port to get a good bond.

IMHO, I would rethink the extra screws. You want a bond that will work and not leak. Dow 795 is the go to product; no experience with VHB tape.
