Ah, well, then....
![]() I'll save myself by being pedantic.....If it's a Cherub with a 12' skiff rig, it's not a Cherub but a 12. Throwing 12 rigs on Cherubs was been an occasional trick for years. One got 3rd in the 12' skiff nats not so long ago. Interestingly, there was some evidence of a (very) slight shift away from skinny flat (ie UK Cherub type) 12s recently, but don't quote me on that 'cause I have yet to confirm it. However, it seems to confirm what the "coffin" designers say; skinny flat boats like the Moth, Cherub and Aust. Skate work really well but only in a narrow power/weight band. So how is the UK 12/Cherub going? Edited by Chris 249 |

I had a couple of email exchanges with David Lee who designed Nuplex - Nuplex is hard chined with the chine beam at about 750 - 760mm. The next version, the S25, is going to be more like 850mm wide at the chines. Apparently the aim is to allow the boat to sail deeper angles downwind due to the extra lift from the hull for better VMG. Nuplex seems to be very very fast upwind and reaching but the extra tactical option of going deeper should help win more races... Yes the Cherub is not actually a Cherub as such, but I couldn't resist it. |

Gotta agree with Chris....... Totaly different animals and would not compare the 2. As far as thrill factor the 12 is not second to the T. However I would not say The T is second either. Boath boats are awsome when pushed to the limits. (as with many other classes) Edited by Tornado_ALIVE |

Blobby, that's what I was referring to; I spoke to Alex (Nuplex's
owner) at the Interdoms but I hadn't checked things over with David Lee.
I also spoke to Emmett Lazich, world Moth champ, 49er gold medal coach and 18' and 12' sailor. He reckons that the super-skinny Moth hull woould not work on the bigger skiffs because the shape has too low a top speed limit. The Moth is super quick on close and beam reaches in 15-20 knots compared to boats like 505s and FDs, but Emmett reckons it's knots slower than the 12 off the breeze. Coupled with Nuplex's problems "bogging down" at times, it's an interesting shift - because some of the top skiff designers were musing that a giant Moth may be the way to the future. Maybe that's not the case. |

From what i've seen of 12 footers they tend to have alot rounder hull shapes compared to the Cherub's harder chines. Can anyone tell me why this is? Does it make them easier to control at high speeds? |

My theory is that the Cherub hulls are bolt upright hulls - you shed about a knot for every 2 degrees of heel, but really quick when upright. This is probably exactly right for a moderately canvassed single string boat which is what all the current UK designs were when on the drawing board. Twelves on the other hand have a lot more power, and are rather more challenging tkeep bolt upright every second so slightly more drag in exchange for more tolerance to heel is a good call - especially when the static waterline beam is a bit narrower as well. |

Yep, that's what the 12 guys say.
