Need help with dimensions for rear lazarette hatch

I could really use the help of some BCC owners here. My BCC (Hull #13) came with a wood lazerette hatch. I have not seen another BCC with such a beast, for what it’s worth. I have ordered a new 'glass hatch from Todd at CGMW, but the dimensions for the mold/hatch he has do not seem to be consistent with mine. There is a distinct possibility that my wood laz hatch might have shrunk from moisture loss, at the time I measured it (October). If anyone who has their BCC nearby, and can confirm measurements for their 'glass laz hatch (outside top dimensions) I would greatly appreciate it. Hate to buy one and have it not fit. I can’t imagine that they changed the deck mold and associated laz hatch size, over the years.

Thanks.

I have hull #16 so its probably the same. She’s battened down for winter in the harbor here but if no one else has a quick answer I would be happy to go down and see if I can get the measurements.

Thank you Ron.

I get 27 1/8 x 18 3/8. I can only gaurentee that to an 1/8th of an inch. He that helps.
