For singlehanded sailing/racing:
An F-16. Either a Blade with carbon mast or a Stealth. If A cats had spi's, that would be a serious contender.
For two-up racing, distance races etc., the 'turbo'ed B class.
A 30-40 foot racer-cruiser to take the family sailing and some north-sea races. Preferably something fast while still manageable by the admiral (wife) and me when not in racing mode. I still drool over those Lock Crowther Southern Ocean 50's..
That brings the count to three, so I guess I just dont have _a_ dream boat but several..
