I would most definitely fall into the category of hating Portsmouth racing to the point that I quit going to events that did not have enough boats for one design racing and did no racing in Florida for several years before finding a one design boat that was being raced.
My reasons are: I race not only improve my own sailing skill but to also prove my skill. I want to improve boat speed and tactics. If you are not sailing the same boat that I am on, whatever it might be, then the comparison is mathematical and the race is a drag race not necessarily tactical and I don't enjoy that. Also as accurate as the Portsmouth ratings might be for some boats, they are not good for all conditions. I want to know that I won or lost because of my actions not because of ratings. To most sailors, I appreciate that it is about getting out on the water with friends and having fun and Portsmouth ratings allows multiple classes of boats to do that.
