blaze type boat with assy is a good concept IMO, but it should be developed from scratch, not as a bolt-on to the blaze.  The hiking element increases the 'accessibility' as turning corners in a singlehanded trap + assy boat is blooming tricky, and the plank on the IC/AC/DC seems to be a tricky skill to master - I tried once and had a huge laugh but also fell in a lot!

if you could narrow the water line of the blaze, give it some more rocker and lighten it off (I hear rumours they are ~80Kg hull weight which must surely be 'improvable'), while giving a similar mainsail configuration <~10m2> with single-line launch/hoist and drop assy then you'd be on a winner, don't know about whether the racks would need to be much wider, they look pretty wide to me already and you have a c'board and knock-up rudder on the boat already so no worries with estuary or pond sailing either.
Feeling sorry for vegans since it became the latest fad to claim you are one

The boat was never designed for a kite and while it might encourage a few outsiders into the class initially, long term it will loose all the original class stalwarts and the new blood will soon realise that they would have been better off buying something designed for the job.

If all classes had followed that mantra then the Fireball would have no trapeze and spinnaker, a N12 would still weigh 100kgs (or what ever it used to be) and a Merlin Rocket would still be a Merlin and flying a tiny tiny kite with no pole inside the forestay.

Everything should move on ... even the Laser now has XD controls...

It's just a matter of managing the process.

to me i think replacing a peice of rope or a pin is far easier than a hull.

I think you are wrong ...

At the 1999 (I think) RS200 Nationals held off Weymouth beach (the far end with steep shingle) we came back in one day and a nasty shore break had developed whilst we were on the water. Many boats got damaged coming in; the main failure was to the moulding holding the pintles; this was caused by the rudders being levered up against the surf. The LDC team I believe repaired over 20 boats over night so no-one lost any racing; hats of to them for that.

The other case I have seen of wide spread transom/rudder damage was at the Fireball worlds in Durban in 1994. We had to launch through full on surf, just down the beach they were surfing!!

The boats that had fixed rudders had "no" problems just sailed out through the breakers then put their rudders on; some of those with lifting blades broke blades and transoms either as a result of the boat getting battered backwards and the rudder slamming to full lock and causing damage or through too heavy handed steering snapping the blades. We had a lifting blade and left it in the boat and sailed out rudderless.

A dagger rudder is a lot less liable to breaking the blade and the transom and is easier to steer with when not fully lowered; plus it's a firmer hold when sailing.

I disagree Rick,

The N12 and Merlin Rocket have evolved, they are lighter, more refined but in general the same type of boat they always were.

Putting an assymetric spinnaker on a non-spinnaker boat is more of a step change and likely to cause the class more problems.

I think its safe to say that, refinement is an output of restricted classes, development is an output of development classes.

Now to my knowledge the Blaze has never been development class !

So, the Fireball adding kite & spinnaker wasn't a step change?

What about the N12 going double bottomed?

Plenty examples of a class making a step change in it's rules ...

Then craiggo why are they developing a new boat off the back of the existing hull??  It will in essence be a new class, so why not offer an assy kit which would make it another arm of the same class.  Much like the Vortex and the IC. 

Why would it cause problems for a class, if it is genuinely a bolt on/off option??

Blaze Weight ..... yup there are some heavier early boats out there but plenty of light ones ... as in many other SMOD classes if you bother to weight them (we have !).   Older hulls can put on a few kg but much of this can be removed by improving hull ventilation. We did weight all entrants at one of the bigger meetings (and their hulls) in 2008 and we think it is something a few other SMOD classes might like to consider.

I've selected individual hulls from other SMOD manufacturers as a punter in the past and I know plenty of others who have done the same. Cirrus decided this was not an acceptable way forward ourselves as it is a complete pain to 'manage' and it always leaves the suspician that YOU might get 'a clunker'.  It is so much easier if every buyer is certain that they have an identical chance as far as new equipment goes that is. 

The Blaze is weighted with centreboard in and all lines and fittings and the CA minimum is 72kg - nothing special.  We quickly switched to Epoxy to allow Rondar to easily build below weight and then bond in correctors up to this minimum.  The minor variations you get with epoxy and the greater variation you can get with polyester in hull weight are simply removed if you build/supply this way.

This is with wings .... 2.5m width does come at some weight cost but it does give the Blaze its 'go' whenever there is a decent breeze!   Take them off, leave out the centreboard and corrector weights and we could claim a daftly low weight  !  Incidentally the 100 will have an identical hull BUT the minimum weight can be lower and still allow us to net out any build variations.  

All makers can claim lighter weights but get the everyday production SMOD on the scales whenever you get a chance and check a few claims out for yourself. 

Cheers - Blaze720

I really like the look of what's been done there and only wished that the
option was properly available when I bought the Phantom.   I still miss
the kite from the 200, Vareo etc and the only reason for selling the MPS
was because TOW was too limited to get my circus skills up to scratch...
hence a Phantom, it'll keep me sailing until something more appropriate
hits the market.

if someone's prepared to take the bull by horns and develop a
singlehanded hiking asymmetric; add some upwind leverage with carbon
racks (I agree with Simon Payne on the metal bars thing) then I'd be damn surprised if it's not a popular new boat option.

Think this concept... B14 singlehander and you're about there. No
dumbing down in FRP and 'versatile' marketing campaigns (in other
words, no nasty plastic beach boat with racing upgrades...) just a balls-
out hiking blast-fest with an asymmetric that can actually get around a
club course to its handicap.... can't be that hard.

regarding dagger foils... know what you mean about the MPS Ian, it's a
tight slot and I pro-lubbed the foils before every sail. But that's the price
you pay for not having geysers come up through the gasket like a sh*tty
laser or something.

 

Well said James.  Something like the Mx ray that was a rapid hiking machine upwind.  I would love an MPS but i just dont have the time or if i'm honest the patients to learn how to get the most from it.  I would love a single handed hiking boat thats as fast as a 300 up wind, with the vareo blast factor down.  I thought as a cheap alternative would be a blaze bolt on kit!!
