Re: 1989 Doral Prestancia aft cabin access hold
Sounds like a good plan, but I won't address this till the spring now... She is getting winterized soon..
You're so lucky over there, we have to use our boats all year around

If you get the depth, length and width measurements before putting her to bed for winter you will have done the job a hundred times in your head, changed the layout a few times, perfected the installation process and selected the most appropriate materials before the next season starts, should only take an hour or so to finish the job after all that.
If the height is available I would add a surround to the top of the well so that the clear top is not screwed directly into the hull, this top is an inspection cover and will need to be removed for services and cleaning etc.
