Portsmouth is a big tent that allows dinghies, monos and multihulls to race - it happens.
This refers to another one of those believes (w.r.t. inability of a measurement based system) that is simply not true.
The basis of NMBR is the F18 performance. When the F18 or H16 (as the biggest best attended cat class) performance is determined against a regulary raced monohull then both systems will have been calibrated to eachother and all other ratings can be determine by calculations.
There is really no difference between Yardstick systems and Measurement based systems here with respect to accuracy and practicality.
Portsmouth allows for a Hobie 20 with a spinnaker, a Supercat 22, a singlehand Nacra 20 or Hobie 18... other systems don't account for these not-uncommon occurrences in the US - what modifiers are available in Texel and SCHRS?
Texel doesn't use "modifiers" as these changes are already included in the basic measurements. A modifier is a typical yardstick invention to have a yardstick do something that it doesn't do automatically. Correct for an obviously wrong rating of a rarely encountered non-class compliant boat. A measurement system simply regards this modified boat as a seperate design, like is regards all different designs, and produces a rating for in the same way as it does for all other boats. This is actually one of the strong points of a measurement based system.
It seems to me that there is a rush to do some work to set up a new system that will replace a system that needs some work. Do you see? Work to avoid doing work... Someone's always trying to rollerskate uphill.
Seems to me that the vast portion of the work has already been done (Texel, SCHRS, NMBR)
