It's 2 pieces. The inner oval it attached to the underside of your hatch to double the thickness and stiffen it. The outer oval donut shape will attach under your deck for the hatch to sit on. 

   THANK YOU! 

Just make sure you cut on the correct side of the lines, it can get confusing with nested pieces. What I do is write the name of the part on the actual piece, then do squiggly lines on the cutout scrap (in this case, the thin donut between the two parts.

Snowbound,  I do see on the other drawings where there are like 3 rims or pieces all one drawn in another that they do a better job of showing this and I have written the actual piece name on a couple of these. Very good advice though and thank you for your kind help. I still need to write bow and stern on some of the panels, too. I could put it together all back wards and crap, I'm sure!  lol   

 There are 5 pieces to the WoodDuck hatches. The sill, a spacer both of which are fitted inside the boat;  a rim (the thin oval ring which is attatched to the sill; the hatch cover itself and a doubler which is glued to the underneath of the hatch cover. If I get the opportunity today I'll take a photo for you.  

Here's pictures from my WD12 build:

Have fun,
