Cutting in tunnel XF20

Ready to cut in tunnel. Boat is upside down still sitting on molds and stringers. I will spread stringers out of my way. What do I do about two molds that are in my way. Guess I can cut them down enough so they support the tunnel any insight will be appreciated

Just as you said: cut them down to make room for the tunnel.

So I cut out for tunnel and of course it’s too long. I think I can recover with filet and tape. Question is do I tape flush across bottom. Thought I had seen some pictures but can’t find now.

The tunnel plans include a drawing showing the suggested layout of the tape and wide fabric.
Sorry to hear that you cut the opening too long. If it is only one inch, build up fiberglass tape there, with offset edges, up to minimum 3/8" thick.

I checked and the fiberglass layout for the tunnel is on drawing B233/14.
If, as you did, you build the tunnel as a box, away from the hull, you still have to use the tape as I show, with overlaps, inside and outside.
