94 PS 190 Platform sag

[h2oskifreak]

I have a 94 PS190 (new to me last spring). I used the boat pretty heavy all summer and she ran like a top. Only put 30 hours on her but only ski the course so it was hundreds of passes. Now that winter is here I plan to do the "projects" I didn't have time to over the summer. The platform needs refinished. I know about the various threads and ways to approach the finish, but my question is the lack of a middle bracket on a 94 and what shall I do with the minor to above minor sag my platform has? I do not know if this is new or been this way for years? Should there be a mid point smaller bracket? I hate to drill my hull if there is a better way. Will this come out if I lay it on a flat surface with weight on it for months, and if so is there something that will help it be more corrective? Looking for thoughts before I start my refinish.
