Hello,

We have a new to the family F28 Corsair trimaran and are in the process of builing a really large sun awning.  I have purchased some 1.5oz ripstop nylon spinnaker fabric and wonder about using that double-sided construction tape like people use instead of sewing for spinnakers.  This sun awning will be approx 20'x15'.

I plan on having 3 seams running the long way on this project, with the longest 2 being almost 20' and the other being about 12.5'.  This will be a lot of sewing that I can use my old zigzag Kenmore for, but I'm curious about the spin seam tape technique and whether it will be good to use here. 

I'll use bolt-rope edges, and would like suggestions for the diameter rope to use for this, also.  I'm considering reinforcing the edges with Sunbrella, cut into strips to make a, say, 2" binding.  Is this overkill?  We have an old LZ1 machine which will do the Sunbrella edges and bolt roping easily

The ripstop fabric is silver, actually a  grey, and our Sunbrella canvas color is Spa, a new color, to me, anyway that is a grey-green with a hint of gold.  They go together real well, and match the grey non skid areas of the deck.

Thanks in advance for your help,

I'm sorry, but the ripstop nylon is a poor choice for an awning.  Of course, it depends on how much you use it, but if it lasts a season, I'll be surprised.

Hi RcKnight,

We won't be using it much more'n we'd use the spinnaker, so I hope we get away with it.  We got 1.5oz ripstop.

The deal is that it's BIG.  We're covering up all the way out to the floats on a 20' wide tri and covering about 20' of it's length.  The fish'll love us.

On our previous boat, an Island Packet, we had a Otis Permasol shade awning.  Itwas bulletproof, about 1/3 the size of this one and about 25 lbs. 

We didn't go with white; Linda Pardey (http://www.landlpardey.com/Tips/Tips_2002_January.html) had a piece on her Website about the difference in UV resisitance of different colors of nylon sail fabric.  White lasted the shortest for some reason.  We went with silver; actually a grey color.

Your right tho, it won't last like that old canvas one.

Hi guys,

We actually have quite a few customers using 1.5 oz Nylon ripstop for sun awnings. It will not last long if left up for days or abused but is a great choice because of its lighter weight. I like the idea of reinforcing the edges with Sunbrella and using rope (go 1/4"). Also the PECO tape or C3 basting tape will work well as long as the edges of the awning are sewn. That said I would still sew everything as spinnaker cloth is so easy to work with and the C3 tape is quite expensive.

Thanks, Matt
