In the 1st pic I see worn carpet and a small sagging deck. Can't see the carpet in the 2nd pic cuz it's a little dark, but still see the sag.
You have 2 ways to go here, one is easy and the other is more involved.
Easy way is mount a clamp on stern mount TM on the bow. It looks like there is enough above the deck to clamp onto the gunnel. If the tiller is too far away to steer, a ball connected extension using a length of PVC will take care of that.
The involved way is replace the deck so there is a level playing field. Using scraps from the deck, build up a standoff for a bow mount TM or raise the new deck. Raising the deck makes a nice place for batteries, too.
