How much more surface area does a Blaze have than an Aero, and how much more structure do you need to support a rack system and/or wings?

I'm sure the Blaze could be lighter (and more prone to dings) but Aero weight? Of course it can't. Its bigger.

.....it's amazing what they can do.(etc)

.. But don't - and for good economic reasons.  There are some classes that will have niche appeal and some with a cult following and a very few that become benchmarks.  Hankering for "what is not available today" on this and other forums simply will not make it happen.  If you are after a niche class ..one that does not exist already well you will frankly need to dig deep, splash the cash, and develop it yourselves.  If you want to subscribe to a benchmark class on the other hand you could do a lot worse today than but into the Aero class.  ... After all some of you have looked, tried or sailed just about everyting already out there and still found them all  'wanting'.

Alternatively - settle down in the class nearest to your 'wish it was' list.  A real world class.   Go sailing, do some more, even more and some more besides and keep working at it.  You have more chance of getting 'good'  by working on your own sailing habits than you ever will by 'jumping' classes every year or so or wishing for 'new' ones on forums ....

Good to know I've missed some time - is covid over yet?

On Weight, the Aero was designed for the materials. The Blaze wasn't. I'm sure the Blaze could be lighter, and twice the price, but Aero weight and not so crazily fragile it's not usable in the real, 2020 world? No.

If its so easy to build the perfect craft down to a very low weight, why was the V2 heavier than the Exxon Valdez?
Everything I say is my opinion, honest

Blaze hulls are around 51kg before wings and fit-out, correctors etc.  It is a comfortable weight for builder to produce and hulls really have proved to be long term durable...   This means the older hulls are still good, can be easily renovated and provide a very cost-effective way into the class - a key issue that is often underestimated for any class looking to grow these days as ever.  They sell on word of mouth, and there are always potential newbies looking to buy boats of all ages.   

Of course it could be lighter but would you want the possible warranty costs if you were involved in a practical commercial way ?  ... or worse still end up marketing short life hulls.  The model works - some recent fleets have even grown from nothing to 25+ boats in little more than a season and a half with a mix of new boats and older first boats.    It is a class model of what can work with a good class association working with the builder - it is today a growing, prospering and relatively a very successful dinghy class.  But if you have one and really want something different selling is quick and easy - so low risk if you want to try one for a season or so.. 

As for a 'perfect' boat for GRF - (and that maybe excludes the Aero 9)  Simply stated the Blaze is not right for you, that much is blindingly obvious, at least to others although many are no doubt amused by the varous troubles and tribulations.  Trapeze boats aimed as a small minority of the dinghy population won't give you decent fleets in all probabability - as you may have found out already.  Developing something from scratch is expensive and risky - you've tried that as well.  The only realistic option imo therefore is to go with something  like the Aero - but either 5 or 7.    Don't like that after a season ?  Should be easy enough to sell but that looks like the best option for you frankly..

(Will this right old saga of the 'ideal' boat for GRF ever end ?) Wink

Yes - shape and surface area are important.

Flat panels and a low surface area design reduce weight. 
Epoxy for high strength and low water absorption. Carbon fibre in high load areas. Light and stiff.

The builder lied to me.

It was a cost thing I wasn't that sure of the design so didn't want to commit beyond vinylester, just as well really.

I should have listened to Dan at the time, but you know me.. can't be told.

If, when, I do it again, I'll use ply first.
