I think you have hit the nail on the head there
Looking at the top 5 participation 
Laser - simple, large volume so good secondhand, equal racing in theory 
Solo - large volume and relatively simple 
Laser - radial as above
RS400 / 200 - good assymetric boats without going over complex

You don’t get a complex development boat until 10 the Merlin Rocket, I hadn’t realised until yesterday that it was slower than the RS400 it inspired.

Thinking back to the mid 90s, working in a chandlery and Topper dealer, I'd day the hype for the assy (the asymmetric revolution) was at least as big as for foils. And the Iso was still hanging around at the dinghy show. At least in the UK, the legacy can still be seen in slow, easy to sail boats sporting bowsprits and kites. Keeping the easy to use bit, scrapping all the revolutionary trimmings of twin traps, apparent wind sailing and very high speeds.

It is difficult to see how foiling is able to trickle down in the same way.

Interesting figures Chris 249. 
With big enough foils you can get anything to foil, foiling Optimist is a example. To be an advantage you need the smallest foils you possibly can which means a very light boat going fast. It is thirty years since I seriously looked at the maths but if you can get the boat starting to foil at ten knots (with the extra foil drag) the foils will be much smaller than for a boat where lift of is say seven knots. That is why the Moth works and othe craft simply don’t 

I have never really enjoyed cat sailing I feel you disconnected from the water, the feeling of relative speed of a dinghy lifting onto the plane simply feels faster, swooping over the water on the end on an IC plank even better. I think foiling looks even more disconnected.

I think you are ‘preaching to the choir’ I expected lots of counter argument when I started the thread but it is nice that it isn’t just me that feels it is over hyped. 

In the last eighteen months I have traveled to a lot of clubs with my daughter sailing her Optimist. I have a mate and we always spend a good hour or two touring the dinghy park. There are the odd splattering of Moths and Waszp about but all I have seen actually sailing are:
Waszp, out a loooong time briefly foiling now and then but generally Mirrors where going faster, it was a lovely F4
Stunt Catamaran, work of art not enough wind, displacement mode all the time
Weymouth, 3 foiling moths actually up and going very well
Foiling windsurfer, going ok but didn’t look like it was massively faster than conventional one

I do think foiling makes our sport richer but it is just a small sideshow.

Dead right, and if high speed was the main driver windsurfing wouldn't have collapsed as it got faster nor would most people in many countries race yachts rather than dinghies. If "flying" was the main driver, people wouldn't bother with foiling boats but would be out there looping windsurfers and jumping over Brighton Pier with a kite.

One thing that seems to be forgotten amongst the hype is that the speed increase in most boats is not all that dramatic. The Small Catamaran Handicap Rating System guys, who analyse many races, initially rated foilers at 7% quicker but now they are rated 4% quicker. It's the same with the MOCRA rule for offshore multis. For simple physical reasons it seems that most boats don't get the the enormous speed boost from foils that we Moths and kites do.

Interestingly, 4% is the same sort of speed gain you get from adding a kite to a cat, but adding assys to cats didn't cause the same sort of hype as adding foils. I've just been trying to do more research into the arrival of the trapeze and realised that I must re-title the relevant blog post, because no one seems to have hyped up traps (which add something like 2% to a boat's speed if I recall correctly) in the way they are hyping up foils. And the fact that most cat sailors still haven't bothered with kites, which are arguably a cheaper and lower hassle way of adding the same amount of speed, makes one wonder why anyone would think most of them will ever bother with foils.

Still, I think we may be preaching to the choir on this forum, which unlike some others is made up of people who actually sail rather than just talk about it.

I stand corrected, I was more making the point, if speed was the main driver catamarans would have much bigger slice of the cake than they do. 

Cats need the same room as foilers but not as restrained by draft (Dart, Hobie cat etc). Considering the effort that must have gone into establishing clubs in the dinghy boom there must be many ideal spots for catamaran clubs but few were started.

Continued, this way I can see the picture
I have highlighted trapeze boats, spinnaker boats and those with PN less than 1000. It is clear that the boats people actually sail do not include the adrenaline rockets. Don’t get me wrong an RS400 etc etc aren’t slouches but not twin wire asymmetrical or foils. Fascinating stuff, at least to me

Thanks Dinghy show and PN launch day, (went sailing instead)

Anyway as I said in the first post it is not 100% scientific as I know the more technical and foiling boats don’t generally do handicap racing. Here are this years PNs sorted by returns,

Hang on a bit there Chris, I think the context for that is needed. I'm sure the vast majority of boat owners who are lost to sailing sell a boat, but which way round is the cause and effect?

I have seen, for example, people who have got a bit jaded with the sport and simply need to take a break for a while, have a period of mad boat buying in which they try umpteen different classes in the belief that the problem is in the boat choice, not in their mind.




If I recall correctly, the message was that there is a tendency to drift away in the period between selling one boat and buying another, even if the sale was made with the full intent of buying anew. Therefore, Dave said if I recall correctly, the aim should be to avoid people having to buy a new boat each time they wanted to move up a performance level, because even if they did fully intend to move up the speed ladder many of them never ended up buying the new boat.

I'll check the video up later. EDIT - part of it is in the vid here at 30.09 on for a minute or so. I think the 25% may have been from Dave or Steve on SA or somewhere else in this chat.

It does seem to chime in with some things I've seen although I wouldn't put it at 25% - but then most of us here come from much healthier dinghy scenes than the Clarks do. 

I don't really know much about selling boats - it's not really something I've done. They just tend to keep on hanging around.

PS - looking at that vid again, I see Dave says something similar to what I have seen before, in relation to mountain biking. Essentially he says "how come we've created these devices that have an amazing level of performance but the sport is declining?"  The assumption seems to be that if devices have amazing performance, the sport should do well. That assumed link between speed and popularity seems to have very dubious basis in fact.

Dave also says that the fact that people who can afford fast boats often buy them indicates that people prefer speed. Surely that cannot be true, because we all know that there are many people buying keelboats who could afford skiffs, cats or foilers, and many people who buy skiffs and cats and foiling dinghies who could afford foiling kiteboards which are faster. And of course, the same is true in other sports.

As I said, much respect for the Clarks, but when you come from a wealthy family that has been fascinated with speed under sail for three generations you may not notice that most people really don't care about it.
