Deformation around Hatch

Posted by Bo on Jul 13, 2004

I am to the point of cutting out hatches in the decks of the 16lt and 17lt I have had under construction for about 2 years. I am planning on making flush hatches of my own design. I would like to make the front hatches quite a bit larger than the plans call for. I am concerned that the deck around the hatch opening is going to loose its shape when I cut large holes in it for the hatches.

Has any one else had this problem. Is there any way to reinforce the deck before I cut the holes? Is it fairly easy to force the deck back into its original shape with the ring stiffeners installed on the underside of the deck around the hatch opening?

Thanks for your comments.
