I finished the second side curtain - went a lot easier than the first - and looks better too. Oh well, the better curtain is on "my side" of the boat.

We are now starting on the rear pieces, and have to order some more Strataglas for the front.
One thing that I didn't go too well on is estimating the materials needed. I have had to order Sunbrella twice; silly me - I thought 4yds x 60" of Sunbrella would have been enough.
One issue, and I am not sure why I am doing this, other than to replicate what was there - is that the current curtains use two layers of Sunbrella. One on each side of the Strataglas - effectively making a Sunbrella/Strataglas sammich.
The Sunbrella color is Captain Navy, which is a very dark blue. It looks lighter though in the flash photos. Sunbrella is some strange stuff - its acrylic, and you can melt it if you iron it too agressively. The manufacturer does not recommend ironing because you can shrink it - but we had to make the facing with an iron - but we were very careful in applying heat.
This project is certainly turned out to be more expensive than I thought; so now I have a better idea why shops charge $3K for what I am doing - there is a lot of expense in material, and a lot of labor.
I did though, find a place that sells Strataglass "seconds" at deep discount. I can get a 54" x 111" standard sheet (kind of odd size) for $40 vs. $100 for a prime piece. I bought two sheets and they claim to be 90% useable - and in both sheets, there was a very very minor blemish; one that certainly will be masked by the normal wear and tear of the curtain. And I was able to cut one out.
I have learned several things whilst doing this project; things like cutting strips on the bias (45deg) so that you can put a slight bend in them to match the irregular size of the original.
We also went out and bought two 6ft by 30" utility tables and put them together so we have a 72" x 60" work surface. That is an abosulte necessity - you cannot do this kind of project on the kitchen table.
The most frustration has been the constant re-threading of the lower thread bobbin. I have solved the problem somewhat by purchasing a bunch of bobbins and having a stock of them handy as I sew the piece.
The thread I am using is V-92 weight UV Resistant Polyester thread with a 14lb tensile strength. I cannot break it with my hands.
One of the things that ends up making the pieces look great is the use of binding. Here you can see I am loading the binding tool with Sunbrella binding.
It can be a bit tricky using this gadget. I have two binders, a 1" and a 3/4" binder. The 1" binder works pretty good, but I am having some difficulty in using the 3/4" one.
One of the secret weapons is stuff called basting tape. I have used several rolls of it, and it sure maks things easier. You simply tape the pieces together before running them through the machine.
One of the best parts of the curtain is that the similey zippers are virtually waterproof. Here is one example. The sides of the Strataglas is banded with Stamoid vinyl, then a piece of Stamoid banding was used - which tends to overlap and creates an interference fit.
This is on the outside of the curtain, so it should be quite good at preventing water from coming in. I saw a "professional" job at the boat show last weekend (the same place that quoted me $3K), and they simply put a zipper on the inside of the smiley and left raw Strataglas edges. I think that'd leak. So when we are done, we'll have an enclosure much nicer than what $3K will buy.
While not really required, the straps that are used to hold the smiley open when you want to vent the bridge have green or red snaps. This I thought, would help in installing the curtains, since you would not arbitrarly grab the wrong one - unless you don't know your red from your green.
I'm gonna put in a few more goodies in the canvas, and when I am done, it is going to be a class A project. I'll post more photos as I progress.
The Sailrite machine has performed flawlessly. On one piece of the curtain, I had to sew through 14 layers of Sunbrella plus 30 gauge Strataglas, and I had to run it through manually (cranking the wheel), but it was just a small part - maybe 2" in length, but other than that the machine routinely runs through 6 or 8 thicknesses of Sunbrella without accord.
This is the part with the 14 layers of Sunbrella (which includes the banding). You can also see the nice seal the Stamoid makes for the smiley zipper in the photo.
I also found that I could sew completely through #10 marine zippers - but again, I have to do it manually by cranking the flywheel, as well as slowly. If you look closely, you can see where the thread goes right across the top of the smiley's zipper.
Another simple, but nice touch is these zipper pull extenders.
Again, I have never done this kind of thing before. But the folks at Sailrite have been very helpful, they have tutorials on-line for a very nominal price, and they will answer questions promptly. They do get a bit more $$ for their stuff, but they also offer outstanding customer service, and that to me is worth a few extra dollars.
The only thing I did not buy from Sailrite is the Strataglas seconds I found. I saved about $180 by doing so, but I have dumped a bunch of money at Sailrite, so they should not feel bad.
Time to order more material...
