Dealing with hatch boards can be a pain. I wanted an easy way to cover the hatch without having to handle the awkward hatchboards. I purchased the H260 pop-up cover but it does not have a door. It is fairly over sized, the left side is about 5 inches larger than the companionway and the right is a good 8 inches oversized. That oversized battens and the weights in there force the thing to fall in place perfectly everytime. Heres a diagram of the cover

Heres some pictures of the cover in use. The whol thing rolls up into a compact package.
