Nos if you put in an inflatable keel you'd need to make up stringers as at the moment the floor seems to use the keel to keep it flat... if not for that a sausage keel might have been an easier job.

Ah, didn't notice the lack of stringers!

In the beginning when I saw the images I thought missing stringers would need replacing until I guessed a wooden keel SIB wouldn't need them.

Just been looking at a 1975 book (may have been written in the 60s?) on inflatables where they said the V-shape floor would be formed by a wooden or tubular steel keel with inflatable keels the new idea.

Yes thats a great idea, i will use that method fenlander 👍🏻 and like you say make a prototype first to get it right.
Yes i think the keel did sit in that slot at the bow, i have a snapped-off ply 'hook' shape that was in the bag with the valves I suspect that was part of the keel that sits in that slot. And yes the front board is fixed
