One of the great advantages of this material is it is basically the same as GRP with much higher imapct resistance, So any construction you can do with GRP you can do with this.

So for example to match an A cat construction for weight and stiffness you would use 0.5mm of new GRP/PP both sides of a 5mm foam layer, and to make the FX one you use a 1mm skin of GRP/PP both sides of a 5mm layer of foam.

Many thanks to Carlbohannon and and Rolf Nilsen for those numbers, I will let everyone know the results when the tests are performed, if anyone has any more data (Wouter?) I would be pleased to hear.

By the way when you describe cloth as being 8oz or 6oz is that 8oz per square yard?

All the best
