1987 ART (Advanced Rig Technology) Rad Wing 5.8m2 cut away windsurfing sail

ART (Advanced Rig Technology) Rad Wing
A new concept was presented at the first ART product line meeting (Schutz, Pudenz, Richter and Spindler), the “cutaway”. The group decided to bring ART to the market with a splash. The ART RadWing was the design which set the windsurfing market abuzz. The RadWing was a winner in magazine tests, and powered Monty to take the Johnnie Walker Trophy at Weymouth in 1987.
The trophy reads: “THE JOHNNIE WALKER TROPHY FOR SAILING EFFICIENCY Presented to Monty Spindler at the Johnnie Walker International Speed Week 1986 for achieving 23.35 knots in 13 knots of wind +179.5% of wind speed”.
The efficiency of the RadWing at Weymouth is significant considering that the current Windsurfing World Speed Record (49+ knots over 500mtrs) was set in winds of 45-55 knots.

The RadWing may have been the first production windsurfing sail which had an induced free upper-leech as a design feature. Free upper-leeches design is the norm regarding performance windsurfing sails. RadWings were in production for five years, more than 25,000 sold worldwide.

I have two. But both are starting to delaminate real bad by now.
