2 years comes from the fact that this is the average selling age of boats, probably more like 2-4 years (2006-2009 are the years of boats I've seen for sale in the past 6 months)). The top guys tend to sell their stuff faster, but that is always the case.

Having worked with both epoxy resin and vinyl ester resin in mass quantities, I would take the epoxy any day, except in this case the class rules forbid it. Vinyl ester resin is typically not compatible with "exotic" materials such as carbon and kevlar. This rule, combined with the minimum weight rule, forces the manufacturer to build relatively heavy fiberglass boats.

I'm glad to hear that the majority of the class feels at little to no disadvantage racing a boat thats been through some stuff vs. a brand new boat, if the old boat has new rags of course. This clearly indicates that the boats are well built and meant for a long life, like the N20. More used boats on the market is always a good thing for class growth.
