I believe the truth will be in the middle with a dry weight at around 8200 kg.
For racing the Splendide shows good results on long distance racing...
First in ORC 2 on the Collin archer Memorial race 2010 (540 miles spinnaker up) see Stichting Colin Archer Memorial Race - Uitslagen 2010
and First in ORC 2 on Scheveningen-Brest (Race and Rally) in 2011, also making number one overall!
