About 25 years ago there were still good ketch designs favoured by cruisers. One of which i admired in those days were Moody 44's. İ am sure a great many more were being produced then outside the existing classics.
Probably by todays standards they were not as fast and efficient. But if my memory serves me wright they were good, able cruisers, a dream to sail and much easily handled.
Designs have evolved, gone the full circle round and came back to much bigger mains and smaller head sails. On the other hand Ketches have dissapeared.
We have today much more efficient furling systems for the main, better winches, and autopilots to keep your head into the wind ofcourse. But i wonder how much more trouble is eradicated by technology whereas a ketch rig minimised the loads and problems at the onset.
I wonder how much do cruisers benefit from the fractional increased efficiency of a sloop compared to a ketch? How much more demanding and costly are all the sail handling systems of a sloop of equal sail area? And what other versatilities are lost in terms of reducing sail.
I remember seing these boats under genoa and mizzen only when it blowed. And nobody said they were wanking!
