Hi Rolf,

With regards to your question about carbon jib track. The ITA rules state

Rule 7 (Materails)

c. The materials for rudderheads and tillers, tiller connecting arm, mast tiller, spreaders, beam attachment straps, blocks, pulleys, cleats, compass holders, wind indicators, and bowsprits are optional.

d. Except for such fastenings, all marerials when dry to the measurer's satisfaction shall be of high electric resistance.

Reading this, it states that the jib track shall not be made from material that is low in electrical resistance.

I think the jib track has been overlooked by the class rules. If you are not allowed to use carbon because of its low electrical resistance, than they also should not be using the metal I tracks.

I say build a carbon one....... I don't think anybody would protest. Or you could call Marstrom to find out if its is class legal or your nearest National/International Measurer.

Maugan, for your info

Stated in Rule 7

g. Tornados built using such prohibited materials shall remain illegal: however, they shall be permitted to race in the club and local events for evaluation purposes, provided that they are registered with ITA (not the National Authority) and also provide:
i. both hulls are indelibly marked on the outside of the transoms with the letter 'X' and with a number allocated by the ITA.
ii. the mainsails have a letter 'X' of size and position in accordance with Rule 6(b). The letter 'X' shall be either in addition to or instead of national letter(s).

h. The International Class Fee as stated in Rule 2, shall be paid in respect of each experimental boat although it remains illegal. Such illegal boats will not be permitted to race in qualifying open meetings of any kind, National Championships, European Championships, World Championships or the Olympic Games unless approved by the ITA and ISAF as required by ISAF Regulation 10.3.6.


I could not see any problems with you racing this type of boat at your local club but if you were to enter a Regatta, If somebody had a problem with it, they would have grounds to protest you out.

You may want to register the boat as an 'X' boat if you got it to avoid this situation.
