Topper International took over Catapult in 1987, and in 1990 Jon Montgomery helped with design of the TI rig, covering sail Nos 2000-2200. A 10sq m Dacron/Mylar sail is supported on a 7.2m luff groove mast with halyard. Dave Jennings continues to campaign this rig successfully in the TT series.

The sail has a bigger roach than Comet, with staggered batten spacings, and a straight foot. The fixed wishboom is kept, with a lighter mast compared to Comet.   Left: Alex pushes the TI across Lake Bala Topper offered the two rigs together for a period (shown below reunited at Bala for the 25th Anniversary Regatta in 2007)
