scooby_simon,

Weight
Beam: Righting moment
Efficiency of kites: very quick development here
Regular updates to keep the development classes in check with the one design classes

In the F18's class the Capricorn when measured to SCHRS comes out with a number well below the F18 101.

Tornado's, F18's, F16's etc have moved forward with speed but the likes of the Dart 18's etc have not (nature of one design) but the ratings have not kept up.

No system will every be perfect, but if you have a statement saying "The purpose of these regulations are to enable trampoline multihulls of various types to race together on a comparative basis, and to protect the interests of the owners in keeping development under control without hindering further research"

You need to keep your finger on the pulse

How did you hear that they are looking at changing SCHRS? has ISAF payed for more development?
