The fact is Hobie designed the 16 many years ago and reframed from changing it and as a result have sold 120,000 plus boats and are still selling today.
Laser have done the same thing except they are touching on 200,000 boats.
The Mossie is a one design boat with a little room to move within the rules. Apart from a weight change and construct materials in the late 80’s the hulls we use today still fit into the original rules written in the sixties.
Changing the rules and in turn the shape of the Hulls just because a boat builder wants to change the way the boat is made is not a good enough reason. Especially considering the current method used in glass boat has stood the test of time (20 years). If you have a talk to experienced boat builders that have used both two and three peace moulds. They are still out as to the best method.
The Mosquito is not a modern boat it is a design from the 60’s and you would have to agree the design is still putting in good performances today. Just this last weekend in one race the first boat over the line at the drought buster regatta was a F18 followed by your cat rig Mossie with spinnaker 2nd behind you there were Taipan’s, a stingray and other Mossie’s. A well sailed Mossie can mix it with the modern boats
We seem to be starting down the road of changes every year? For what reason? are we trying to be a development class like the A Class or do we want to be like the Hobie/Laser staying the same so people can buy a 20 year old boat do it up and be competitive. We have resisted this type of change in the past.
There is a age old saying “If it is not broken don’t fix it”
