Why bother? You'd only end up with a half a$$ed patch job after a lot of work. Both of them look like they'd only take 1/2 sheet of ply - get new teak ply and re-make them.Are they crumbly as in soft wood fiber coming out or are they just de-laminating a little? if the plies are just letting go why couldn't you take each out and turn they over, spread the plies gently and run epoxy in between and then refinish, and re-install?
