Tufnol is a composite material so I would say yes you can. There are many different types of Tufnol.
Whale, Carp, Kite, 6F/45 etc. They all have their own applications.
Any of the above would be suitable for something as simple as a rudder tube.
Just a thought.
Who would be responsible for having all the measuring equipment calibrated?
Will the MYA have a budget set aside to each and every measurer in order to have their equipment calibrated?
This should be done yearly. By a calibration company. Certified. Dated. Signed off. Date of next calibration too.
Or will they have to do this themselves? At their cost?
I wonder how big the que will be for that!
Because if a sail is 1 micron too big, (about a thousandth of a human hair) it is not legal.
What will the tolerances be? plus or minus a millimeter?
I could perhaps understand if we were flying comercial aircraft. But radio controlled yachts?
Stupid.
