The I-20 is a modernized version of the M-20. It is a 20 ft (6.1 m) sloop rigged scow with a spinnaker. The boat was first built at Melges Boat Works, now Melges Performance Sailboats. The boat has two bilgeboards and two small rudders. After a couple years of experimentation, the class settled on its current rules in 2002. The new rules permitted a larger, asymmetrical spinnaker and a carbon fiber rig. It is currently made by Windward Boatworks. In 2005, Melges brought out a new Melges 17 to compete with the I-20.
