Further, whilst it will always favour smaller kids or ones who can stay small enough at 16yo to make the experience count without sinking the thing, kids of 11-16 come in vast range of size and weight so tune ability is a positive.
As a point of order the oppie rake adjust is a stainless cup with thread adjuster quite expensive, similar to what is used on Finn Europe ok.
The zero system really about having replaceable plastic bearings a deck and heel as a means of avoiding the wear issues in the likes of laser etc where you are wearing out the grp at bdeck and heel which is very hard to repair.
If doing this then there is negligible on cost to add a couple of chocks, and make the heel cup so you can flip it back to front, thus giving tuning options and a bigger weight range.
Maybe shouldn’t have bothered :-).

Yes you should have bothered, I think they are wrong having rake control is a good thing- 

It must be better to able to tune the boat relatively simply vs pulling the sail to death so it needs new sail every regatta

Interesting isn't it, how what we're used to conditions what we think looks right. On most of those classes the droopy boom is an artifact of a one design sail and bend or rake way in excess of designer's intentions. Aerodynamically it's a nonsense.

Isn't it about leverage and leech control more than aerodynamics?

I must admit on the looks side of things I find the boom angle the hardest to accept.

That rather demonstrates (one of the many) problems with the Optimist more than anything else. An adjustable mast on an entry level kids boat is ludicrous.

I had to laugh at the raking rig being a disadvantage as the sailors could not possibly understand what to do with a very basic rig tune system. Many of these sailors might well have been a kid with an optimist which guess what has a raking mast. Not sure how the 10 year olds cope with all this technology.

Makes you wonder if the Laser without the XD kit would have scored even better: having a usable kicker and outhaul must be very confusing for Olympic wannabes.

Still puzzled about the D Zero's ranking, given the applause it has here and the way it looks. On the other hand, it would not be the first boat to over-do the fine bow idea.
I think the part of the report that the D-zero being too technical because it has mast rake chock and different traveler systems so distracting from the athleticism speaks volumes of the direction they want the sport to go. Also I don’t think the D-zero or the M14 are really set up for global one design quality production. 


I think that they are or could be if the market warranted, nothing easier than finding good partners who can achieve excellent consistency if you can guarantee good volume.

To my highly biased and partisan eye, and given other information coming from the trials from admittedly dubious sources, the report reads like a document compiled by people with a certain agenda, who want to appear as if they are going through an appropriate process. Plenty for me doesn't add up to what I have heard from sailors who have sailed 3 of the 4 boats on trial, and sounds like justification for statements was based on heresay rather than fact or experience.
That said I think that WS have let themselves down by keeping the laser regardless of who the pretender is.  I think too much was made of universality, as any of the pretenders is still a plug and play una singlehander, for which the laser could be a perfectly good trainer / feeder etc.

I guess the 49er, the 470, the Nacra all have loads of moving parts, maybe they want one without?
