Bomar
Bought a replacement forward hatch from Pompanette/Bomar a few weeks ago direct from them. The hatch fit in the original opening perfectly on my 1985 28.5. I ordered the G995--2122 hatch. Even though the sizes listed on the web site didn't match to my measurements exactly, when I got the hatch it matched the dimension of my old hatch almost exactly. Don't take my word for it that the above model will fit. Take measurements of your hatch and proceed accordingly.
