Steve, an RSX (and it's not a board I personally like at all) planes. It jumps, hits 30 knots +...of course it planes. You cannot do that in a 10 footer at displacement speed.
That's the weird thing about this term "planing board". It's inherently untruthful, because just about every board ever built (including D2s) planes.
So you ask "why not be more positive and supportive"? Well, look at the negative arguments the FOD supporters use.
The FOD bid says that "racers" want planing boards - that is (as far as I can see, and the FOD supporters have not come up with a shred of evidence for their view) negative to existing Olympic boards because it says "racers" don't want them.
Look at KP's blog - he says it's time for a "real windsurfer" in the Games, meaning FOD. Sorry, is he suggesting that he and his mates have the right to re-christen RSXs, IMCOs and other windsurfers? It's a silly argument anyway, because the term "windsurfing" comes from longboards.....those who feel the 'planing boards' are a different sport can get their own name for the sport, like boardsailing.
We don't have to all be positive and supportive of those who are themselves so negative and anti other disciplines that they say they are not even part of the sport.
If shortboarders were positive and supportive of other styles, that would be great. They are not so it's hypocritical for them to demand that of others.
The oft-quoted argument "it was all just a fad" was addressed at the SB dealer meeting onk the west coast of the USA, according to a SUP site, where Svein said that windsurfing had dropped much more than other sports normally do after an initial boom.
The doors are NOT wide open to all sorts of windsurfing opportunities when sailors sponsored by a major manufacturer are saying of other disciplines that they are not "real windsurfing". KP is sponsored because he is influential, and he is using that influencing to say that hybrids (not a board I like myself) are not even part of the sport.
The doors are NOT wide open when a major manufacturer is saying "racers" want a particular type of board in the Games, when most racers appear not to sail that type of board and the manufacturer has produced no evidence.
