Well! I am excited for one. Good or bad it is an exciting thing to do and in the public eye as well. Looking at it in the "flesh" so to speak, might it not need sort of rubbing strakes down the hulls to keep such a wide shallow hull going strait without too much helm input?

It looks like a large donna kebab without the filling, can't see it being first to the windward mark too often. It had better be quick off-wind to have any chance of beating something like a Contender around the cans.

Atrocity.

Wide scow shapes and wide boats are very far from being new to dinghy sailing.  The 1800s Sandbaggers and skiff types had beams approaching half their length. The old Kiwi Idle Along had 6' beam on less than 13' overall length.  Elvstrom did an 8'6" wide singlehander many decades ago that he sailed once before burning.  Scow Moths were grest performers in a breeze, largely because they were light, but certainly not so good in lighter breezes.

As you'd know, Formula boards aren't exactly quick in sub-planing conditions, when form drag rises approximately with the square of the beam.  So it's an interesting idea (I reckon scows are a great type of boat) but it's far from unknojn in dinghies.

There's been some small cats with single surface-piercing centreboards that drop down from the tramp's centreline.  The surviving classes down here are quite good performers, able to mix it with anything of their type despite having box-shaped hulls.  So the surface piercing effect may not be a big issue.

I saw the beast in the flesh today at Jamie's. The photos don't really show the scale and size of the thing...quite enormous!!
I'm sure some little titanium guard rails, and an optional lifting keel of a spent Uranium bulb on a strut, you could enter the boat in a Sportsboat fleet if things don't work out in the dinghy fleet.   
Jamie had plans to bog all the hull stringers in today, so it's getting there.  

My 2 pence is though the rig's too small...12.5m2 sail area's a little on the Thai lady boy size, to get it really powered up.  Don't dick about, go straight for the square top 49er rig.  It'll blow ping pong balls..

Looks heavy ? Isn't the idea of a single hander is to be able to launch and recover single handed...and drag it up a slipway or across a beach. !

You're forgetting the step on the inside of the tunnel...

Then I think it'll be round the front, like a Blaze.

I'd make the inner granny bar a little further out - so that IF it does capsize at least you have a useful half step on the way up to the centreboard being as the hull to deck join doesn't look like it will provide anything to step on

Last discussion we were using Vortex or RS700 bits and a K1 jib.

But to get it on the water, it'll be whatever comes to hand, that wide, maybe an RS800 set up, that should make a quick single hander.. Wink

It's around 2 metres before the racks, if you want things to be fast and easy then they need to be wide, that's what happened in windsurfing and the whole widestyle revolution, and now I'm bringing it to dinghies.

Even Wider = Light Guys can make em go.

I'm going to have to go some to tip it over, no doubt I will sooner or later and when it happens it'll be spectacular, but it'll have to be something catastrophically stupid to do it.

I've never like all that silly boat falling over nonesense, why would you design a boat to do that?
