any help would be appreciated

Before posting i did my fair share of searching, after looking into it alot i finally decided to remove my two back benches. There is no noticable difference as far as flex or twist but would like to re-reinforce this while still maintaing the open space of not having benches. I plan on doing some decking and was considering doing some sort of L shaped bracket from the floor to the remaining part of the bench but am not sure if this would be effective or even how to go about doing so. Any input would help and pics would be great. Thanks

Honestly i wouldnt even worry about it, the rails along the top of the boat are pretty dang stiff and it keeps the sides of the boat in check, the middle seat is missing off my 14footer and there is a pretty big gap between the back an front seat and iv noticed no flexing at all in the bottom or sides of the boat in or out of the water. Goodluck!
