If the Tiger was the Olympic class and I was to buy an F18, I would choose a Tiger without question unless it was significantly more expensive.

An F18 class selected as an Olympic class would effectively give that manufacture and unfair advantage in the F18 class. [/quote]

Why? Because you think you will make the Olympics?
the 'One design olympic Tiger' will soon not be able to keep up in the F18 fleet. The other current F18s will certainly undergo developement to keep them competitive in F18 for a few more years before they are superceded by a replacement design.
I know that sails/rudders are fairly easy to swap from one event to another, but the olympic sailors will want to race their one design boats and not get pushed around by faster F18s while they are doing that.
So, the only reason to buy a tiger will to be to race other tigers.
