[C320-list] Sliding companionway hatch

[Dave Hupe]

Mark-
It is good for you to report the ease in replacing your hatch. Mine is badly crazed and i know it eventually will need replaced if not just for aesthetics.  I suspected i could pull it out without removing the sea hood because i can start to pull it past the rear stop easily.  I don't perceive that there are any fore to aft side underside grooves.  Lacking these I have never had leaks. 
Thanks,Dave Hupe

was able to talk the yard into ordering a sheet of 1/2 inch smoked acrylic,
and selling me half.  My recollection is that I was able to cut it with a
fine tooth blade on a circular saw.  (Jigsaws have a tendency to melt the
plastic unless you cut slowly and let the blade cool from time to time.)

My original companionway cover had two grooves running fore and aft on the
underside, about an inch and a half in from each side of the cover.  I
didn't have a way to duplicate them, but I haven't noticed any problems from
not having those grooves.  The original also had two scallops cut into the
front edge of the cover.  I didn't duplicate those, but haven't noticed any
problems from that either.

I didn't need to take off the sea hood to get the old hatch cover out.  I
believe I had to remove the teak rails on either side of the companionway to
slide the cover aft and out from under the sea hood.  I re-used the original
end piece on the edge of the cover facing the cockpit, and the wooden bar
that enables you to slide the cover from inside.  I used the old cover as a
template to locate the screw holes for those pieces.

It wasn't a bad DIY job, although the material was expensive as heck.  Good
luck with it.

Subject: [C320-list] Sliding companionway hatch

Has anyone replaced their plexiglass sliding companionway hatch? Mine has a
crack in it, and Catalina has not responded to my requests for making a
replacement.

My initial measurements have it at 36 and 3/8 inches wide and 29.5 inches
front to back in 1/2 inch smoked acrylic, although this was done without
unscrewing the hood that it slides under. Before I start taking it apart, I
thought I would ask whether anyone had done the measurements.

Currently, I'm trying to talk a local shop into ordering the piece for me
from a fabricator. Half-inch acrylic apparently is too thick for the locals
to handle. Anyone have a different recommendation?
