I have a 2003 Jeanneau SO 35. The vinyl lining in the forward cabin has separated from the fiberglass hull. I am having trouble finding something to get the vinyl to reapply and adhere to the fiberglass. Any suggestions on what would adhere the vinyl to the fiberglass?

Is the vinyl material backed by foam? If yes, the foam and/or adhesive backing is disintegrating from age and needs to be replaced. Over time the problem will become worse. There is no permanent fix other than to rip it off and remove the adhesive, then replace it. New material and the Super 77 spray @Tallly Ho mentioned.
If that is the case a band-aid approach that might work is use teak strips and screw fasteners over the top of it.
In my experience (different boat maker) the adhesive residue is very difficult to remove with solvents. 3M Woodgrain and Stripe Remover chemically converts the adhesive to a waxy substance that isn't sticky, and is much easier to remove with scrapers and rags/solvents such as 3M Adhesive Remover than the original adhesive.

Yes, plain Jane latex rubber. Paint it on both surfaces, let it air dry and press together. You can build up layers if you need to to get better contact by letting each layer dry (you can force dry it with a heatgun). When both surfaces are dry, press together and go over them with a stiff metal or plastic roller. Very safe to use, cheap and was the original contact cement before contact cement was a thing and they started selling the outrageously expensive stuff in the spray cans, although they do work pretty well (some of them).

As I wrote - you need to replace the fabric. The old foam backing is disintegrating and the old adhesive is just goop and adding more won’t help - it can’t be reattached. Read my original post again. When you pull the vinyl you’ll find that the old adhesive is difficult to remove; with conventional solvents you’ll feel like you’re mostly pushing it around and not much coming off. Using the 3M Wood Grain and Stripe remover will convert it to a waxy substance that’s easier to remove. Good luck.

Edit - after you get the surface clean you can re-cover with similar material or just paint it. There are rubberized outdoor rated house paints made for cinder block that can do a nice job on the textured unfinished fiberglass. I suggest using a mold inhibitor additive if you paint. A paint store can match your color scheme. Add molding strips after painting to finish the edges/borders where you cut the vinyl out.
