You can find all the facts and figures, including rig dimensions, for all the I30 models at SailboatData.com. They confirm what John was saying.
Interestingly, I had not noticed the I30-2 TM
model previously. It appears to be the I30-2
hull set up with a rig almost identical to that of the I30-Bahama
. The foregoing hyperlinked names lead the the associated Sailboatdata.com pages where you can see for yourself.
UPDATE: Faster, you beat me to the punch while I was typing.
