I just had a chat with the International Class President.

The intent of the 2010 rules was to get them into into SCR format and not to change any of the rules contained within.

Dyform is still out, the idea to try and control costs. Yes I know this the line in the sand and can be debated.

You can change rig tension while NOT racing. I have to send a request through the ISAF process to get the wording made more precise.

VHF for buoy racing is still out, reason being outside assistance could be had and cannot be regulated, same goes for iphones and other similar devices.

1 steering compass is required, this rule is unchanged.

1 tow line 15m long 6mm diameter is required, this rule is unchanged. I still don't know if the main sheet or other similar sheet can double as tow line, that answer is still pending. Can someone tell me if this is something that is checked at Worlds, has anyone ever been tossed for not having a tow line?
