The standard 17 oz double Bias fiberglass cloth by Vectorply is an E-BX 1700-10 (+/-45deg) with a total weight of 17.92 oz/sq.yd (608 g/sq.yd). This high quality biaxial fiberglass cloth provides more strength than standard 12 oz double bias cloth, but with some added weight.
The cloth helps to bulk up on strength without requiring multiple layers, and it impregnates easily. The weave is retained by a thin polyester stitching which holds the perpendicular 45 deg tows in place without affecting structural integrity.
Experience fantastic results while used during wet lay-up, vacuum bagging, or infusion. The 50" wide cloth is sold by the yard or roll (125 yd).

I am replacing the transom on a 17' Aquasport, I plan to bond ply to the inside of the transom which remains, then do lay ups of 17 oz followed by i2 oz and some lighter cloth to finish. the total would be 1/4 inch, and it will wrap around the top, which I'm thinking I would need to grind a taper into the new lay up and use a light cloth to cap the transom.,Any suggestions for lay up schedule, cloth weight & quantity, epoxy resin quantity?
That sounds fine, you will need a gallon kit of resin. You can do all your layups at once. I would cover it after all the layers with peel-ply release fabric that will leave a smooth finish. Taper the existing edge areas so you can overlap the cloth to tab it in so when you fill and sand it will be even with the existing fiberglass.

I was considering using three layers of 6 oz biaxial to wrap a new plywood core rudder for a 24' sailboat since I believed the 6 oz would be easier to work around the rounded edges of the 1 1/2" thick rudder. Will I have trouble if go with 17 oz biaxial instead?
The woven cloth will be much easier to wrap around a 1 1/2" radius than the biaxial cloth. If you wet the biaxial out first it will make the bend easier.

Is the $8.65 /yard for a running piece 50" wide and 36"(1 yard) long or is it for a square yard? A 3' piece of 50" fabric is actually 1.31 square yards would then cost $11.33 per square yard. Could someone please clarify? Thanks
This is sold by the linear yard at 50" wide at $8.63 per yard, so three yards would be $25.89.
The price is for 1 yard and 50" wide $8.65. The weight of the glass is 17oz for a sq yard.
I'm not sure. I bought this small piece to do some small fiberglass patching. I suggest that you ask the Jamestown staff who would have a clerar answer for you. Dave.
Biaxial cloth installed yesterday
I'm building a dory to row the Grand Canyon in March and we used this cloth for the hull protection
Bullhead City, AZ
well made biax - easy to work with
I purchased the 17 oz biax to use in the repair of the transom on our Bayliner 3270. The repair included plywood and epoxy, and in order to properly reinforce the new plywood it is necessary to use 45 degree biax when tabbing to the hull. I found the Vectorply to superior to other cloth I have used in the past, and found that it layed in the corners easily, absorbed the epoxy quickly, and was generally easy to work with. There are alot of loose threads if you have to cut strips as I did, but no worse than any other matting. Note that cutting this cloth will dull scissors very quickly - you'll need quality tools if you have to piece a lot of it out.
