Good morning. I have an O'day 22 that does not have the forward hatch option. I called Rudy and he said to get a hatch off some junked sailboat and make it fit. My question is if anyone has the basic dimensions of the hatch that will fit the 22? I think it is about 20" by 20" but not sure. I just need something close since the installation will be a custom job of building the gutter to match the contour of the cabin top etc. If anyone has a 22 that they could give me the dimensions I would really appreciate. Thanks very much.
