The resale advice should be heeded if you are not planning on taking the boat to Yurrup or storing it until return.
Me? I'd buy a 21' Flicka and sail her to Yurrup. But then I'm one of the few wack-jobs around here who think small!
It sounds to me like you have the sailing characteristics laid out for you in the previous posts. What I think you need to do now, in your ample spare time , is start climbing up and into whatever boats you can. They vary so widely, especially in accomodation, that you really won't know what is unacceptable until you've seen for yourself. Put your eye balls on 'em.
