Re: Islander 34 Companionway Door
I know this is a little late in coming, but I would suggest making cardboard templates of your existing door panels, that is if they fit properly now, as opposed to simply taking measurements of the sides and angles. I made the mistake when I just took the physical door frame measurements when I was building an AC mount (see the pic) for the doorway.
I had to go back and use the template method to get the "fit" right. My measurements were right on, but the doorway was not true or square, whatever the correct term would be anyway. Since the original doors did fit, it was easy to make templates and work off of them. I wasted some material (cheap wood, but only for the mount you see in the picture below) and my time, because I had to go back and re-measure/draw the templates.
Just letting you know.
