How do you install the inspection ports?

I know I posted this on a similar thread last week, but FYI -
If you're installing the port for a specific repair or upgrade, you'll have more elbow room if you cut the hole in the deck, do the repair, and then mount the inspection port. Other than that, follow the directions from windline, especially the part about the metal blade in the jigsaw. A wood blade will not only leave a more rough jagged edge, but the coarser teeth can catch on the fiberglass, making the cut sloppy, dangerous, or both.
