Soon the cherubs will probably have 15.5m˛ upwind and + 21m˛ down wind..... so getting more 12 skifflike, and therefore requiring a completely different design development route.

I have been looking at the Woof 12 design.... very nice and fair, and with a flattish part of hull horizontal - regardless of the heel angle!

so maybe the next generation of uk cherubs may look more like this.

The current low sail area favours flat shapes that plane early, but need to be sailed flat or heeled to windward.
The best training for cherub sailing is moth sailing where you learn the windward heel thing.

Bugger, I hope you don't change the rigs in that case

I quite like the interesting shapes on the UK Cherubs and there are enough 12 shapes around as it is

Ooops...can I say "bugger" on a UK forum? Insert "crickey" or "dash it" if you please.

Cheers JimC very informtive.

I read you cherub guys are testing bigger kites but wasn't aware you were looking at a bigger upwind sail area as well.

What sort of weight is that Loco Perro, are you having to put correctors in yet or do you just beef up the hull?

To make an 'old' cherub competetive, it is likely that it will need a new main. jib and kite ( fairly obviously, and these do wear out )
but also a longer mast, longer boom, longer pole.
Also the self tacker track may need moving to get some extra area in the jib, and maybe moving the mast.
and the daggerboard might need moving
oh - and the hull shape might need changing!

Loco Perro is around 45kgs - it has yet to be formally weighed as it wasnt "finished" at attendances at recent cherub events. So it will probably need around 5kgs of lead  to be legal. Its a pretty solid lay up compared to a number of other cherubs as I wanted one that would take a bit of stick.  

So far I'm really pleased with it, its a moderate design which isnt that different to some other cherubs around the waterline. The difference is the obviously "big" topsides. The theory behind the design (or reason for picking that design) was realated to the fact we now twin wire. When I'm in the boat and playing with two wires, things occasionally go wrong. I thought a more forgiving hull shape might allow us to get away with the occasional wobble around the marks or mis-calculation of downwind angles without too much trouble.  Only time will tell if I am right - but so far its been fun, and thats what its all about at the end of the day.  

With regard to the proposed changes in sail plan, if they are voted in, then older boats will be able to upgrade and boost all round speed with a bit off effort. The class hasn't shied away from this kind of challenge in the past and i'm sure that it will stimulate lots of playing with carbon and resin. 

At present there's plenty of cherub building activity and lots of interest in the class. Whichever way the vote goes the futures bright and heart shaped.

Class promotion over - have you guessed what I sail?

The UK cherub hull shape may need to change to make it easier to sail ( as loco says above ) with the extra power, however it's not yet clear how much extra power the new rigs will give.
Maybe the existing flat boats will be still be OK, and faster than the 12 shapes - because the sail area is still small compared to 12 skiffs.


lots of hearts posting on this topic!
