Mike, our class rules have a class course already. We do not use a trapezoid, just simply a triangle, windward - leeward.
The one point of sail ALL Wave folks hate is the dreaded and boring downwind leg (in this boat tacking downwind does not pay -- you just head for the mark). So, we try to set up the courses so we have two beats, two reaches and one downwind leg. Most folks like the course.

I think our class mentality is closer to what Harry Murphy said -- I don't think so. Most of the fleet will NOT sail with a Hobie made sail. And while a Hobie sail won the Nationals last year (my daughter-in-law), and have won quite a few of them, I personally like to look up and see a sail that is pretty. Probably about the same speed, but it looks like a sail.
I believe Patrick Green voiced the same thought, as would almost the entire active sailors in our fleet.

So, I don't think HCA would be offering any bargain. What would IWCA gain by compromising anything? We already have a very active class. HCA has NO class.
Sort of like the tail wagging the dog, don't you think?

Other items not discussed in HCA working with us:
*What about this minimum weight issue? We do not have one, and don't want to have one.
*Trampolines made by after market suppliers? Almost all of them are from non-Hobie manufacturers.
*Any other items? How about the mainsheet. Nope, most are not using Hobie supplied line (and I doubt many of the H16 class are either). Most are using Salsa, a great mainsheet for any boat that is light, won't knot or kink, goes throught the blocks with ease, and the list goes on.

So, you see HCA is very far away from what we are doing. The easy solution is if a fleet, Hobie or otherwise, wants to develop and active Wave Fleet, they should work with us under our rules and we can grow together. For example, I am sure there are a bunch of us that would show up in Rochester/Syracuse area if we were allowed to sail under our rules. Otherwise, we have a ton of regattas already on our schedules.
What the heck, the local fleets can bend a bit, can't they? HCA is asking to practically abandon OUR rules to comply.

I don't think that is going to happen.
