Never owned a Mainship, but for various other boats, both sail and power, I've done similar. Using the same flexible fiberglass screen as seen above, I sewed up fabric edging tape around the perimeter as GFC mentions. Rather than use Velcro, which ages quite quickly on a boat, I used brass snaps. Works beautifully.
