Hi all - just joined.

I'm restoring a 1974 all wood GB 48 in Tunisia. Going well, but I'm struggling to find 6 Perko portlights for the aft cabin.

They have 128mm x 320mm cutouts. The wall thickness is 50mm.
In inches: 5" x 12.6" cutout. Wall is 2" thick.

If anyone can help me find or steer me in the right direction it would be super helpful. Orknows of an alternative product.

Welcome aboard. I used New Found Metals ports in our last boat and loved the quality. 316 S/S cast ports.
 
I need a port hole on a 20 year old boat. Grand Banks (Stuart) had it in stock. Rather large, very well made stainless porthole and it was just over $300 + $200 freight from Singapore. I was pleasantly surprised.
