Default Gortex Thread with Sunbrella Experience

I'm hoping to see if someone can report here about having good experience
with Tenera thread, as you originally requested. If leaks are indeed the
norm, either seam sealer or regular restitching w/ dacron may be the only
answers.
If seam sealer works and looks OK on darker fabrics, it could work for me,
but sounds like not so good for you. I have started replacing my canvas with
a slightly darker Sunbrella anyway, to give my sails more uv protection.

I think that part of our problem is that we've having the work done in
the Chesapeake and they don't have experience with these kind of
products/problems. BlueJacket is in Ft. Lauderdale right now (awaiting
our return in a few weeks), but our experience with the with fabricators
there has been less than stellar. For one thing, I think that many of
their local customers don't spend a lot of time on their boats (other
than on the dock on nice weekends and thus don't ever really see how
well the fabrication works) and their other customers are transient and
this not around to complain if things go wrong. We fell into the later
category one job.

I will point out that BlueJacket spends the vast majority of her time in
the Caribbean. This is the first time in 7years that she's been back in
the US for any length of time. We brought her back just to have the
canvas work done. As a result our demands for canvas are vastly
different than a boat in most of the US. When BlueJacket was in the New
England area, I would never have worried about what I worry about now.
The Caribbean sun is brutal and UV resistant V92 thread just doesn't
hold up. I don't want to be re-stitching the bimini every 2 years as we
had to do in the Caribbean.

I will also point out that Sunbrella Supreme is a completely different
cloth when compared to normal Sunbrella. Sunbrella Supreme is water
proof with hydro ratings near 1000 cm vs. hydro ratings of only the high
30's with normal Sunbrella. You don't have to re-coat with 303 type
sprays (which are considered HAZMAT and you can't fly with those).
We're using Linen colored Sunbrella and every sealer that we've tried
leaves a visible mark. As Sue has said, it's like you applied clear
nail polish. For dark fabrics I think that it would be fine

This isn't what you are looking for, Geoff, but your problem w/ Tenara
is exactly what Canvas and Cushions in Hampton, VA told me would
happen when I asked about using it. She said best was to just figure
on restitching after a couple of years. I don't know how well they can
match up to the old needle holes though, if that matters. I hadn't
heard anything about needle size, so perhaps that's what is needed.
The seams that fell apart are now secured by my emergency repair with
3M Super Weathertrim Adhesive.

We've been having problems with a new bimini which we had constructed
using
Gortex (Tenara) thread and Sunbrella. The Ship's Tailor in
Deltaville, VA did the construction. We were very happy with the
fabrication, but all of the seams leaked with water droplets forming
at the needle holes. The fabricator utilized a #18 needle and after
the fact we did a huge amount of
research and have been told that they should have used a #16 needle.
Based
upon partial deconstruction we saw that the fabricator sewed through
the seam-stick tape, as they should have.

We also utilized Sunbrella Supreme, which is a new fabric from
Sunbrella which is MUCH more water repellant than normal Sunbrella.
The fabric had flaws in it which didn't become apparent until we were
using it. Sunbrella
was great and had a rep meet us in Annapolis to look at the
construction. Later we shipped the bimini to Glenn Raven Mills (who
makes Sunbrella) and they were absolutely great. They said that the
fabric was defective and should never had made it out of the factory.
They refunded the entire cost
of having the bimini constructed ($1700) and will provide the fabric
for it
to be reconstructed. I love companies who stand behind their
products!

Next hurricane season we're planning on returning to Deltaville and
have the Ship's Tailor re-make the bimini. Because BlueJacket spends
so much time in the Caribbean sun, normal thread just doesn't hold up
and we've spent lots of time resewing parts of it. The Gortex thread
should hold up much better, but we're concerned about utilizing
Gortex thread again.

Does anyone have positive experience with Gortex thread and Sunbrella
that they would be willing to share? Do you know what construction
techniques were used?
