My old cockpit scupper screens were brittle plastic, and broken in several places. Now I know I sound like a broken record, but I love to use HDPE to make all kinds of things on the boat. After about four years now on the oldest parts, no UV degradation has been noted.
I took a piece of 1" thick HDPE material, originally a toilet partition panel, and bandsawed a rough circle. After turning on the lathe and milling three slots, two new screens were produced in about 20 minutes each. You can see below how they turned out. These were sort of slapdash machined, although they are within a few thousands of an inch of the original where they pushed into the fiberglass. Please excuse the nasty appearance of Blues Image. I spent her weekend time repacking and replacing a couple of trailer wheel bearings. Next item is cleaning, then off to the launch ramp.
I know several people have commented on the free flooding lazarette and mentioned blocking off the outside ports. I didn't like the flooding on my boat either when I first put her in the water, but as someone else on the forum aptly pointed out, this is critical to vent heavier than air gasoline fumes out of the boat, plus making a quickly draining path for water that may enter the boat when you round up in 25 MPH winds. Not that I've ever done that...dang, that was a lot of water!


The hole you see next to the screen was where a motor control cable used to be.
