Well, I was not trying to make any "point." And I have no personal interest in whether people prefer to sail one-design, or formula, or on handicap.
I was simply curious as to whether people sail in open class by necessity or by choice.
When I posed the question, I was not certain what the responses would be, because if people genuinely wanted to race boat-for-boat, I think we would see more efforts to develop and grow one-design and formula classes. (I realize that is easier said than done.)
In fact, of the catamarans that race in open class, few have active class associations, and even fewer have owner-controlled class associations. To me, that is very strange and shows lack of interest in structure, organization, and growth of the class -- and probably also indicates lack of a feeling of loyalty and commitment to any particular class of boat.
