It is a good point and it made me think

The small cats we are talking about are roughly the same width as their monohull siblings. The Max arm lenght will be 6.5 ft instead of 5 ft for the Laser or 5.5 for the Sunfish (For monohulls center of bouyancy to center of mass of a 6 ft man hiking) There is not that much difference in righting arm

These rigs are unstayed. They deflect before they break.

These rigs are way overbuilt but not stiff, they bend

At a gut level, just based on my experience, I don't think I could break a Laser rig if I put it on my Tornado
