Carbon Copy is now running a new colour scheme following some refurbishment.

The handbook to 1936-2000 has an excellent picture on page 171 of Bruce Johnson's 'Texas Flood' showing constant (but adjustable) tension tracked shrouds. (all in green string). I looked at doing it on my boat but once I priced up the parts, decided that for club racing with my daughter the money was better spent on beer, J2O and crisps!

I thought the crew was there to just keep the spray off the helm!

Looks lovely, though.

Note change in foredeck overhang from original! Measurement issues or manufacturing convenience?

Must be something to do with the mac software. If I run XP on the mac  I can read it ok.
Damn, another year without foiling!

Having been prompted by the Latest Chapter I just tried to download the application form pdf and got lots of twiddly garbage. Is this just me?  Is it a hint that I should sell the 12 and buy a foiling moth instead? :'(

I had a similar problem and found that the bottom of the tenon was flat. When upright the mast was then sitting on the front edge of this. This seemed to cause the mast to invert under tension. 

I took a file to the tenon and put a curve on it. This seemed to do the trick.

Sort of like sailing a laser with a rooster 8.1 rig in the light stuff and gradually moving down to a 4.7 rig when it's honking. Most classes don't allow this, with the RS300 for example we have to nominate the A or B rig and stick with it.
 
However, just because other classes don't allow it doesn't mean we shouldn't consider it, especially considered in the context of handicap racing at club level, where frankly, our main consideration should be making the class more accessible and more popular.

Essentially the lighting must be within 1m of the rearmost point of the unit, whether that is the transom or the projecting mast tip.

I went to the system described by Gareth a couple of posts above. A split end goes up to the boom, along to the middle of the boom and then to hand via a serious ratchet. In theory it is only a 3:2 purchase, compared with the aft sheetings 2:1. However the advantageous sheeting angle from the boom to hand , where you are pulling the sheet towards you, rather than down, (when the boom is near the centreline) means that the 'perceived load' is very similar to aft sheeting.
 
Other advantages
- when caught by that unnoticed lull when at max hike, there is something with which to haul your a**e out of the water.
- There is no crew obstruction.
- There is less string.
- Downwind, if the crew is not paying attention while sitting on the thwart you can flick the mainsheet and clonk them on the side of the head with the ratchet block! (this requires thought in siting the block correctly in the first place):-/

Oh, and I forgot to say (it may be obvious to you, it may not) that with a gnav you can't use a normal gooseneck as the gnav pushes down and back, and as  a result would force the boom off the gooseneck pin as you cranked the kicker on. 
 
Seems like a really good way to make space for the crew, though.

Most of the ones I've used are pants. The 4000 and 29er have the moveable end of the gnav sliding along the mast or boom and they often barely work unless you put effort into cleaning and siliconing etc.
The one on the RS300 is excellent as it uses large rollers at the mast end.  It also has two rods, one either side of the sail, which allows a more natural sail shape. (unless you fancy the 9er style double sided sail foot - though I have a feeling that this is outside the class rules!)

Roly, Just managed to stop my 5 year old sending you fan mail. However he is impressed that roly sails a 12!
 
We don't have to change anything. This thread is kicking ideas around because concern was expressed that while the open meeting circuit was doing ok, the 12 at club level was struggling. There are some clubs that have a fleet, but not that many. This is a way for those that don't go to opens, Burton Week or the AGM to talk to those who do.
 
However, think where we'd be if we didn't change anything, ever. Uffa Kings all round, anyone? Look at the picture of Mr Jones and Witch side by side.  A development class needs to keep (slowly) moving on and re make itself for the present day.
 
Nobody is suggesting 12 foot bowsprits and twin trapeze, but the sail plan now is pretty much the same as pre carbon mast, but now we can lose a lot more power than before. A bit more sail area probably wouldn't hurt the lightweights but would give the slightly larger amongst us a bit more drive on the transition to planing.
