It's a small price to pay for all the additional "FUN" berny! besides it's like all things new, it only becomes easier the more familiar you are with it.
Personally I agree with you about the "A" class concept for a 14' cat! I really like the "purety" of a 14' set up cat rigged within an "A" class style formula, I don't even like carrying a jib on a cat unless there is a crew. But it appears that the market place is dictating a spinnaker at the present!
