Matt, the Tornado was a very tight rule that effectively limited the development costs to gear and sails. The platform for all intents was one design and one manufacturer.

Yet the development costs to run a Tornado at a top level were in excess of 100k EURO a year, its totally insane but its also the reality.

We need a one design boat for the games, simple as that. With a box rule you will always have massive costs and to be honest: does the racing get better because one team was able to develop a better boat than the rest??
