Why not do what the Hornets do? - keep the shute but lose the sock so it's loose under the fordeck and have a 'kipper line' where the downhaul goes thru a plastic ring on elastic between mast and chainplate which is stretched as you pull the kite down. When the kite is all the way down you let go of the downhaul and the kite 'pinged' back under the fordeck.

Admittedly both the fordeck and cockpit are a bit bigger and the kite a bit smaller so it might need a fair bit of pin but you get the advantage of less wear on the kite.

I was half thinking of a stratigicaly placed kick bar so you hit that

Thanks guys I think we are coming around to staying with the sock but....

Granite ( AKA Phil ) So even with 3 patches ( this is the other option ) the
sock is still long? Have you got a spacer knot / konts?

Hey man I like your thinking... this could be an option.

I had something like the hornet on the Trifle, this was only the 15m kite yet it caused a few problems, ie - capsize, it would float out and get tangled and caught!

At the moment I am using a spacer knot to ease the passage into the chute but it does have the effect of making the kite longer when in the boat.

On my previous boat I tried the no sock and elastic pinging forward method and it did work but you need to isolate the kite from any string under the foredeck e.g. self tacker or pole launch string or it will get sucked in.

bear in mind that you are still going to have to pull the kite back as far as it currently goes and it has to then ping forward without getting caught on anything and ends up being folded into half its current size
If it doesn't break it's too heavy; if it does it wasn't built right

Does anyone know the new PY for the new amount of sail area for the Cherub?

I can only find a py of 980....is that with the 21sq m kite and 15.5 upwind area?

Thanks, kasey

all that isa required is a little mesh to keep the kite forward of the mast

Just a bit of a wild idea but....

Maybe you could use a section of cat trampoline with a cringle put in the right place to allow the halyard to run through. On the drop the material would then pull in to the boat with the kite and once done it would all spring back in to place. Not sure how you could secure it, maybe use bungee cord to give that extra bit of stretch....

Like I said just a mad idea bu it may be worth investigating...

The handicap for the Cherub based on last years figures for 12.5 upwind and 15 kite is 975

For the 2005 rules with the larger sail area at the moment the only thing you can do is guess a number as there has not been enought boats on the water for enough time to calculate one.

Essentialy the handicap is 975 for all cherubs, however the race officer can alter the handicap at there own descretion depending on the age and rules compliance of the boat. There is some guideance on the Cherub web site. http://www.sailingsource/cherub/

At the moment from the sailing I have done in my 2005 rules boat I have no real idea as I have yet to sail against other boats in any sort of consistant wind speed with me sailing the boat any where near its potential due to it's new ness and systems still not working fully. and I have yet to sail against another 2005 rules Cherub

I have had bursts of speed but also bursts of sitting stopped in the water with everyone sailng past.

So far in the boat I have found that in less than 5 Kts is is quick espesialy down wind as I can soak much lower with the bigger kite than I could with a 97 spec boat.

In 5-10 kts it should be quicker but I have been having  problems keeping the weight forward when marginal two trapizing and the dragging transom combined with the lack of practice moving in and out has causd me to be incredibly slow. The T-Foil rudder should cure one and practice the other(I hope)

10-15Kts This area should show real speed increases up wind as we should be able to start planing up wind much earlier, I have yet to sail against any other boats in this wind speed so have no real idea, down wind in 15 Kts the boat felt fast and increadibly bouncy, but the GPS did not give much better speed than in a 97 spec boat in about the same wind but it is difficult to tell.

15-20 Kts  de-powering conditions and the 97 spec boats are probably still fully powered up so the extra drag from the extra sail area would now be starting to slow the new boats down in comparison.(Have yet to try this)

20 Kts plus going to be seriously interesting but already is in a 97 rules boat you will just have to respect the rig more and hang on.
