A lot better than most people believe! Decent sails, clean bottom, go to windward as well as a Sigma 33, and off the wind with the staysail set you'll leave them behind..Ketches go to windward...Yeah!.. regards Tony W. ( had mine for 15 years)
Totally agree, ketches do go to windward. Had a twin keel W33 ketch and even she could leave many modern boats for dead to windward given F5 plus and a bit of a lop. But as Mudplugger says you have to work at it, get the sails setting properly fit a mainsheet traveller etc etc.
In fact she went so well we bought a Solway ketch, the 36' version.
