Folks,

As much as I have and still do admire the C class and those involved the Class has affectively developed itself into extinction. The move to the solid sail makes it an impratical boat. So you will never see them in numbers.

If you created a C Class MK2. Ban the solid sail and leave the working sail area at 300sq ft or maybe move it up to 30sq metres and add a 30sg metre spinnaker. Leave the hull length at 26ft so it is not too difficult to move around and limit the beam and mast lengths for the same reason.
Set the min platform weight at a weight that would enable the boat to be built from ply with a layer of 200gm glass either side. This woud enable a competative boat to be built without it being essential to go to super expensive methods and materials. Not that they would be built from ply just that using this as a benchmark will inherently limit the need for very expensive methods and people could still enter the class from their backyards should they desire.

I'd leave the crew at two people.

I think there would be people out there that would get a lot of fun out of such a project, whether building, sailing or just suporting.

Regards,
Phill
