Hi NickS
The Taipan is a brilliant cat but if you really are going to sail regularly in 20-25 knots, maybe you need a modern Mosquito with a spinnaker, rather than a Taipan. The smaller rig will make life easier and allow you to enjoy the use of a spinnaker. Of course if there are Taipans to sail against where you are, then go for it!
I agree with Wouter, the Yvonne sailor is talking rubbish.
