Mozzie hulls are only cheap if you are looking at old second hand ones. There's no difference to the work and materials that go into a Mozzie hull than goes into a Taipan hull. With the Taipan hulls being built overseas THEY are the cheap option (or should be!).

My "tune", such as it is, hasn't changed because the square top question died when no-one supported Bob's rig and hasn't been raised since - until now. Don't think I'm against changing anything (there are class rules that have no impact on performance that I would change to modernise the boat but I know I would be wasting my breath suggesting them).

I'm just waiting for someone to come up with a proposal that will take the class forward (ie actually improve it). I've thought about it plenty and sure a square top will look real flash but no-one has figured out how to make it work as well as what we have now. Specifically a boat and rig that works well with any combination of cat, sloop and spinnaker.
