Wouter: All actual information I have about the event is found on http://www.christmasrace.org
The information I relayed, came from another T-sailor. I can ask him about the spesific conditions, and wether there was any crew/setup changes. Much information can be gleaned from the race reports tough. Jo-jo Polgar was the one with the carbon stick, and the austrian team was consistently faster last season.

The alu masts shall weight in at no less than 23 kg's with all fittings and running rigging attached. Tip weight is 10.25 kg's or 10.5 kg's depending on wether there is an internal jib halyard.

There was some information about carbon mast data on the tornado.org web site, but it has vanished, as has the class rules (somebody probably has done some error in uploading or changing the site). I dont know the tip weight, but I can ask around..

You can see the profile for the new mast on : http://www.tornado.org/uploads/documents/15.pdf

There was quite a bit of information on the carbon stick in the proposed new class rules that was pending ISAF approval. When they become on-line again, I think you can find the tip weight there.
