I've done this in the past. The slower you go the less chipping occurs on the edge. Routers are supposed to work better. I've also heard of people turning their saw blade around to get cleaner cuts. It's supposed to melt the plastic a bit instead of relying solely on mechanical cutting/chippingOh, and you can cut it on a table saw

Tap plastics will manufacture anything you need.
Where ever you have it made try to have them cut a grove/ Chanel in the top side of the hatch. Make the Grove/Chanel about 1-1/4 inches wide and approximately 1/8 inch deep along the back edge of the hatch. Try to keep the grove/Chanel about 1 inch from the back edge of the hatch. Then make another 1/4 inch grove/ Chanel about 1/8 inch deep all along the under side of the hatch on all three sides. Right, left, and the back.
This will correct Hunter's design flaw regarding water infiltration during heavy rains. The grove/Chanel on the top will Chanel most of the water off the hatch that will be concealed under the decking hood. The bottom Chanel will not allow any run off to enter the cabin because the water would then have to run uphill.
Hope this helps.
Capt. Robbie,
You can cut a channel with a router. Set up a guide, so you cannot exit the area you intend to route. For 1/8” deep, you can make a single pass. If your channel is more than 1/4” deep, set your router to make multiple passes.Any idea how I can do this myself? Already have the hatch as I said on here...

You could also use a table saw if the channels run all the way to the edge. That would require a Dado, so you do not have to make mutiple passes.
The 1/4” groove/channel on the bottom is how far from the edges? Left, Right and Rear...B crites

Capt. Robbie,
Okay, Thanks...I’ll check into the measurement...do I take it that the groove/channels do not run to the edge of the sheet? Meaning the whole set of grooves/channels remain approx 1/4” from the sides of the sheet...I don't remember exactly, I think it was made approximately 1/4 " from the edges so that the plastic would not chip.
My guess is you made a new hatch for the companionway, not the top slider over that hatch, am I correct?My boat came with a single plexiglass hatchboard for the companionway, and I ruined it trying to remove a layer of messy looking stick-on window tint that someone had put on there. To replace it, I bought some tinted Makrolon (a polycarbonate like Lexan) remnant pieces on eBay and made a two-piece hatchboard set. I found the stuff very easy to work with, not much different from hardwood. I cut it on a table saw and used a router table to put a rabbet joint where the two pieces come together.
