Cuddy " walls " - how thick ?

[bgreene]

Inside cuddy of my V21, anyone know how thick and what's behind the carpeted upper side panels ?

Thinking of screwing in some shallow hooks to make rod holders, but don't want to be risking if it's just fiberglass that's only X thick.

The separate carpeted access panels left and right inside the cuddy are removable, and I could build in approx. 3" diameter holes to allow rod butts extra room.

Just toying with the idea so far.....
