Rick,
the new Javelin 16 does not comply with the actual F16HP rule in several aspects: for istance it weights some 10 kg (or 22 lbs) less the minimum weight limit fixed by the F16HP rule; the carbon mast at 9.0 m is 0,5 m (or 1.7 ft) too long and too light etc. The midgirth measurement rule is only one DIFFERENCE, even if the most interesting from a developmental point of view. In fact BIMARE boatyard is willing to compare seriously the performance of furling gennakers (hooters) versus conventional asymmetrics.
The same tests will be carried out also on the Javelin 2. I hope to be able to provide you with the outcome of these tests in the next few weeks.
