New Found Metals made this recommendation (below) for the berth portlights in the Pearson Ariel. Any thoughts about increasing the size? Original size (outside dimensions) are 5.5" x 9.0", they are saying I can go 8" x 15.

"You have ample space to go with our 5x12 oval stainless. You cabin bulkhead looks a little thin so you can thicken it up by 5/8" by using our Teak Spacers. Our O512SS has outside dimensions of the frame at 8x15" . We have drill templates that assist in drilling our fastener holes in the right place (our ports bolt together) and will show where you need to remove any material. We can send you the template to be sure the port will work for you. A little larger port looks better on your boat besides adding light and more air." -New Found Metals Nov 12, 2019
