I'm near the beginning of a
long-term plan which ends up with my wife & I cruising in semi-retirement. We've been spending our sailing time learning the ropes (quite literally

) of sailing on a local lake in a Corsair.
I've been told, by several people I trust now, that learning to sail in a Corsair is an excellent foundation for learning to sail any sloop. Is this an opinion shared by folks here or would people recommend some other method / priority?
I, personally, am not very interested in racing (though that seems to be the focus of Corsair sailing) as my interest in sailing is purely the feeling of freedom I get being out on the water. I note, and agree, that sailing in races has helped me learn better ways of sailing in the different conditions available. Still, I'm interested in other's opinions on the matter. Should I learn in races first, or learn first and then race to improve. I'll admit to being a little frustrated at the slow progress of learning through races and am strongly considering lessons outside the club to get my skills up faster.
Finally, I'm kind of hoping a few cruisers out there could tell me how they started. I've followed a few blogs now and I'm surprised at the number that seem to have bought a boat to cruise before having learnt to sail. Is my long-term planning unusual? Or is it considered reckless (if very interesting to follow online) to do what these people have done?
