I'm not really sure from the picture, but it looks like the locker to starboard probably has structure in the bulkhead in the front of it. Take a close look at how the wall on the right side of the locker is attacked, if it's tabbed to the bottom of the deck
, or if there are stringers on the hull
that it's attached to.
Look on the outside too and see where the chainplates go. If they come down on the hull
where that is mounted on the inside, it might be important.
But ultimately, you'd have to what most important, and how much work you want to do. My suggestion would be to get used to curling up... (I'm 6'3") or consider a different boat.
