The single greatest feature of the Inter 20 I found was it's stability in unstable conditions. With 20 feet of hull and big fat bows, you can relly push it hard going downwind. You can easily de-power it upwind too. It's nearly impossible to overload it. It drives like a Cadilac, smooth and fast. It's not a light, twitchy boat like the F18HT's or A cats, which will usually beat the I-20 to the A mark, but when you pull that big spinnaker out and point it downwind, it will take you on the ride of your life, with complete stability in big wind and waves.

The one big drawback is the same as for the F18's, it weighs nearly 400lbs and you must race it two up, per the rules, not because it takes two to sail it, it certainly does not take two in light to medium wind. I used to sail mine solo here on a lake in up to 17 knots, and yes, I did right it solo many times. It is a great ride and on a distance race it won't beat you to death.

They are getting expensive. I have heard rumors of $19,000 for a new boat. That's why you can't find a used one.
