"It is chilling to see the mozzie doing so well despite their 38 years of age. Although they were continiously upgraded over time."

Hi Wouter,
Agree - continuous refinement and small changes have kept the boat reasonably competitive. We had wanted to add a spinnaker long before we heard about F16 but had always met resistance from the One-design mindset folk. the advent of Formula sailing helped push us over the edge .
Now looking at ways to get the boat one step closer to F16 again, watch this space... Small improvements along the way, backed up by some bigger long-term ideas, and the Mozzie might have another 20year lifespan in it yet, after all, there`s not much faster than a Tornado in the 20ft fleet and the T is just a big Mozzie !!
