I suppose that Jack is disingenuous to think that cat sailors are simply "sailors" and others can be "categorized" by "interest" like "dingy" or "keel boats".
Agreed. The survey wording contradicts the reasoning in his reply. Don“t be fooled by word tricks, if there is a dinghy and keelboat option, there should have been a catamarans or multihulls option either - not to mention windsurfers, kites and (why not?) foilers.
I guess you all know that kites are also applying for the Olympics.
