I'll re-phrase my question, if i made a 21sqm jib, what would make it a jib rather than a spinaker? |

For one the kite is made of a different, much lighter material than the jib.....i don't think a jib would be any good in a kite material?.....too thin??? The shape would be completely different, even comparing a jib/genoa to a asymetric....a jib has a slightly curved foot and a kite has a very curved foot....goes very high at the clew. ........if you want a jib that big.....get a Flying Dutchman!...............plus, it wouldn't comply with the Cherub rules Kasey. |

So is it the material that makes a spinaker a spinaker? If you made a jib out of spinaker material would it be a spinaker? |

NO!!! although....spinnaker material is defined as "spinnaker cloth". Just checked in the English Dictionary.... "Spinnaker = a large triangular sail carried opposite the mainsail of a racing yacht running before the wind." "Jib = a triangular staysail extending from the outer end of the jib-boom to the top of the foremast or from the bowsprit to the masthead." Just keep the jib for upwind and the kite for downwind!!!!

We have been here before.... a few years ago.
It would be possible ( under cherub rules) to use a 'spinnaker' that is very flat , used upwind like a huge jib, and to have a very very big mainsail. However this would ( probably) only be any good in force 1 or less upwind, and no good in anything downwind. So it's an expensive way of (perhaps) more speed upwind in conditions when racing is cancelled. |

I've just looked at Cherub class rules at http://www.sailingsource.com/cherub/chframe.php and wow, they are short. Since, as has been pointed out, RRS 50.4 is excluded, there does not appear to be any definition of what is the jib and what is the spinnaker. You can't have a 21 sq m "jib" because "The combined area of the mainsail and jib shall not exceed 15.50m2". As has also been said "Only one spinnaker may be carried on board in any race." Therefore if you make the spinnaker your upwind sail, you are also stuck with it downwind. Doesn't sound a great idea really. |

I think my question has been mis-interpretted. I mearly meant to spark a discussion as to what defines a spinaker, rather than say, any other headsail. I'm not planning on actually doing it. It's all hyperthetically (spelling???)

Yeh most of it is - i think the main defining point without going into
the rules is the unstable luff, if its got a wire running down from the
head to the tack its a jib! The majority if not all spinnakers also
have sail in front of the luff, as in if you drew a staight line from
the head to the tack there is sail to either side, whereas a jib
finishes along the line! - dunno if u get what i mean

I think what really defines a spinnaker is simply that you hoist it for downwind and drop it for upwind.... like jib is defined inboard sheeted and genoa is outboard sheeted.....just when and how you set it ............it would be pretty interesting to see how a 21sqm jib would be though Kita |

Yer, I get it. But you can get spinakers with wire luffs.
