I could be quite wrong... perhaps the Johnstones could correct me.

The story I heard is that when they took the 30 down to SORC in 79? they found it to be underpowered downwind, so they added 1' to the pole and a larger chute. IOR at the time then allowed them to make the overlap on the genoa larger for free. PHRF at the time wasn't an issue.
