Re: Why a racer for cruising discussion...
I would also take issue with such a narrow definition of a cruiser. As far as I am concerned, if you are going away on your boat for multiple days for the purpose of exploring, or just getting away, you are cruising. You can sneer at such people and say they are not "real" cruisers all you want but the fact is the vast majority of people who consider themselves to be cruisers do not fit your definition.
If I WERE going to leave my entire land based life behind and live on a boat, I certainly wouldn't do it on a pure race boat unless my intention was a high speed circumnavigation of some kind. I doubt many people would.
In the context of your very narrow definition of cruisers and racers your question is pointless, because few, if any, of YOUR kind of cruisers WOULD use a race boat.
