Unfortunately (or fortunately, depending on your point of view), Hobie Cat builds a product that has a very long lifespan.
There are boats out there that are over 20 years old that are still very competitive - that don't have Comptips. Case in point is my 1985 H-14 that was the lightest boat at the North Americans last month (3 lbs over minimum). Of course, it now has a Comptip for racing.
I'm not going to re-iterate the arguments about the Comptip. Suffice to say that the rule is not going to go away. Ever. Get over it, already.
According to the rules, you are allowed one exemption to race. After that, you must get a Comptip to race, or be subject to protest.
On a practical matter, you're not likely to be protested until you start beating people. They don't want to spend the time in "the Room" any more than you do.
Hobie dealers are encouraged to sell the Comptip retrofit kit at cost+shipping to first-time users. Keep your eyes on eBay, too.
