Hi Peter,
I had friends that circumnavigated and had their windows replaced in
NZ. The NZ folks just laughed at the American yachties every time
they saw screws in the plex and mumbled "leaky boat". There is NO
way to have enough flex/adhesion space around the screws. They use
very large overlaps, industrial Dow or Silkaflex, the stuff glass
buildings use, and require a week in the yard for it to cure without
flexing. They hold the edges own with small screws and fender
washers while it sets, then remove the screws and do a 3/4" fillet
around the windows. Their boats sail in much rougher waters than we
are used too. . .
2 cents, Lee
In my case (C&C 27 MkIII) the PO had screws installed at the 4
corners of the hatch acrylic into the cast lid - I don't think those
are original ... It appears to be where mine is now leaking from (of
course!) Also the windows were re-bedded (probably acrylic replaced)
with screws included every 6-inches or so ... that's (of course)
where the windows are now leaking from (in fact the screws have
damaged the cabin side fiberglass around the window opening and I
can even pull a couple screws right out of the cabin side ....
completely stripped!)
