The saloon ports for my 20 year old Hoyt F-32 had deteriorated to
such a degree that you could only clearly see through them if it was
raining. I contacted Freedom Yachts and confirmed that the material
was Lexan. Lexan is a General Electric copyrighted name for
polycarbonate. Since the patent has expired, like
pharmaceuticals,the generic price today is really reasonable. For
all 6 ports, I paid less than $160, including the fabrication of the
ports. It did not include the drilling of the holes for the
Screws/bolts that secure the ports to the coach roof.
I have rebedded the old ports on more than one occassion and have
used a combo polysulfide/silicone (made by Boatlife???). It seems to
work well but after a few months in the sunlight, turns brownish
yellow. I’m less than thrilled. 4200 isn’t much better because it
cracks after a time. I hesitate to use 5200 because of its
permanance. I’m searching for the best solution that I can
find…please!!! let me hear from the rest of you who may
have found a better way.

GE makes a number of silicone caulks for glazing. I used a black one to bed the tinted ports on my F-30. One GE brand name (not the one I used) is Silfit.

I too replaced my fixed plexiglass windows in my F39 Express several
times with both lexan (even softer than plexiglass) and plexiglass,
only too see them quickly deteriorate into a hazy mess in no time. I
finally replaced them with tempered glass and have been very happy
since. They have already tacken a few sharp blows with no cracking
or scratching. I installed them with 3M 5200 and some aluminum
carpet track along the sides (no holes in the glass, just used the
carpet track as a clamp). The tempered glass even bent to match the
existing curve. Lastly I had the glass cut from my patten slightly
smaller than the original (to accomodate the carpet track) and tinted
pretty dark to keep out the sun. If you are interested I could post
a few photos.

Rich,
I would be interested in how you extracted the original windows and yes, I would like to see some photos…I use the glass polish on ours every few weeks, which cleans them up quite nicely…but it is a pain to continually clean them up!
