Berndt,

?Thank you will make 60 mm.

The material I used is called Oxford in a dress shop. I just looked for close weaved material and then sucked through the material until I found some with a good resistance from letting air into my lungs. So if it is airtight enough and strong enough it is good enough for me. It cost about 2 euros per meter for 1.5 meter wide.? So the sail cost me about 20 euros. Dacron is much more expensive and difficult to get hold of. I also used the wife's elna dress making machine for sewing. So I cannot use material that become too difficult to sew.

Regards

Philip Malan
