The kerfing worked as a means of forming the tight curve near the bow.
I used a 4mm circular saw blade to cut 5mm deep slots in the 10mm foam/.
As a precaution I still heated the foam in the oven before shaping.
This is much easier than than correcting a bad shape later.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
