On Quicksilver, I had to have hatches built to conform to the curved roof. To simply slap those fans onto a flexible surface risks "drumming" caused not by fan motor or blade imbalance but airflow eddies amplified when a breeze is flowing across the fan inlet.
Simple reinforcement with pine spacers will help prevent drumming and leaks caused by flexing. I have used a product called NUTSERT backed with metal fender washers when access to the rear side was available. Google NUTSERT if you need the term defined.
But custom-fit pine seems to be the easiest way to get the job done with reinforcing.
