Actually the 4000 loves a breeze and it likes the waves.  Its very happy in 25K when some of the other high performance skiffs need olympians to keep them upright.  At that windspeed (in my limited experience) its also faster than an Osprey upwind and down.   However I'd also say that the current handicap is about right for the 29er and the 4000.  Lets face it we are only talking 2% when a good shift can be worth more than that.

Most "new" classes initially have a rating suggested by the manufacturer. Is it that favourable ratings are suggested in order to boost results and publicity ?  I realise this will ultimately be ironed out but the ratings in reality vary very little year on year.  The RS 800 actually became marginally slower in 2004.  It races off  822 whereas the 49er with what appears to be similar vital statistics races off 747, some 10 % faster !

The RYA don't publish numbers until they have stats, so although manufacturers may suggest numbers the only influence that will have is if clubs doing returns agree with the estimate. I would expect that the early estimates would be a bit high because it takes a few seasons for people to find out how to rig sail the boat to best advantage.

I remember a mate who knows a bit about rigs saying that he'd boat a new xxxxx, set it up according to the book, and thought it looked dreadful, but figured he'd better try it. After a few weeks of being boatspeeded he thought "**** it", set it up how he thought it ought to be, and jumped up near the top of the club fleet. Then did some comparisons and discovered that the top of the club fleet weren't using the official settings, but ones pretty close to what he'd worked out.

So until the top of the fleet had worked out what the rig settings should be that class was probably handicapped artificially slow.

The arguments about skiffs not handling breeze are in actual fact a bit pointless, they are designed to be fully powered up at far lower windspeeds that boats like the 420 or fireball, and as a result seem overpowered in 30+ knots of breeze. 

As for pulling the cunningham on, its effect to flatten the main and let the upper leech blade off in the gusts actually makes the main more efficient in high winspeeds, where minimising drag created by sail camber is more important as a result of the high appearent windpeeds associated with planing to windward. 

FLAT IS FAST!

Yeah i dont think its fair too say all that daddy and mummy stuff about 29er sailors and the youth sailors because none of my family sail at all so all they are involved in is the dropping off and picking up. All the rest i have to do myself!

I train

I save all the possible money to keep the boat in racing condition

I have to do all the maintenance

I can never get a new sail etc by 'just asking daddy' , i have to save up for absolutely ages and do as amny jobs as possible

and all my school work haves to be done in the week so i can sail at the weekend!

So no if you talk to most of them, many youth sailors get far by not asking daddy but by working hard and have the detremination to keep gonig and do well !

What the modern skiff type boats do have is a modern rig.  Their adjustability is a revelation (but then I used to sail a Laser).  Its quite possible to make my boat feel underpowered in 20Knots and yet fully powered in 8.  The hulls too contribute to the ability of the boats in high winds.  Mine does drag its bum in the light stuff but the minimal rocker, and slim waterline does mean that as the wind gets stronger it just goes faster, unlike the more conventional hulls which seem to have a speed barrier which they will not exceed.

For those of you who haven't tried one consider this.  You put the kite up and being a big kite they really go very fast.  When you get hit by a gust you bear away and go faster still and if you get hit by another, stronger gust, you simply bear away a bit more and go even faster.  It seems endless - the more wind the faster and deeper you go.  The only snag is the manouevers which can be tricky since you have a narrow hull and a big rig.

and then the next big gust hits and you realise you dont have enough weight to push the tiller to stop the kite collapsing from the back because your going too low..... now THATS fun.

Yes, I'm not sure what Yann is talking about.  It's certainly no problem at 30Knots true wind, I recall going down lake Garda at about a Kilometer every 2 minutes and feeling exilerated but perfectly in control.  The gybes were a bit exciting, but manageable, the drops, the hoists and the tacks were a bit hit and miss though.
