There are 3 - 2007 Blades that get sailed hard April - October every year. Also a 2006 that joined this year. All are still going strong. Also an earlier Taipan from the first batch that came over as F16s that is sailed just as much and is prestine. My 2009 boat is at 112kgs and is built like a rock.

Sounds like you have an outlyer to me.
