Thanks for the followup. We were worried specifically about the amount of space surrounding the hatch
that we have at our disposal. We have 2.25 inches at the most narrow point around the forward hatch
before we hit a bulkhead. The salon
hatch has an abrupt change in the angle of the ceiling (20 degrees or so) roughly 2 inches from the edge of the hatch.
I sent the specs off to oceanair, and they indicated that the old line requires ~2.125 inches, and the new line requires 1.6 inches. I'll be placing an order for skyscreens soon, and will eagerly await their arrival.
In response to your other point, I'm planning on shamelessly copying you. Thanks for the info!
