Steve,

I think sailbuilding for windsurfers are more industrialized. Sails are cut and assembled in e.g. China, in a large standarized production run.
Cat sails are mostly buildt and assembled by smaller organizations and are far less efficient in production becouse they can not standarize to the same extent or have the same volume. I am sure you can get the same price pr. sail for Mosquitos as for windsufer sails, if you order 10.000. of them

It's the same with masts, no standarized production for cats, while windsurfers are very standarized. Windsurfing masts are machine buildt, whereas our tubes are often hand laid up. Then the cost of fittings and installing them need to be added. Buying just the extrusion and rigging it yourself is not that expensive (for alu, carbon is a different matter).



What I would like to know, is what fibres and laminates we can use that are not based on oil. Are there any competitive cloths made today that are not somehow dependent on oil/oil derivates?
