To my knowledge the only States in AUS that publish PY numbers are Vic and SA and I don't think either has a signifcant 12 footer fleet. Vic rate the 12 tentatively at 92, where the I14 is 86.5 and B14 96.5, and FD 92.5. |

Their difference in PY between the I14 and B14 is interesting... |

The narrow section is there to specifically reduce the drag due to the surface piercing effect. It uses exactly the same principal as the foils made by a certain Mr. Paterson at Bloodaxe for the 470's. The waisted section has narrower chord, finer radius leading edge and the maximum thickness further aft. That particular foil is made by Alex Vallings of C-tech and he can mould you a nice shiny new one at a very reasonable price. (at least, the quote he gave me was reasonable). |

Yeh sorry about that. Only just started looking at this forum. I noticed that when the pics were originally posted people were asking questions as to why someone would have tried to beat the ferry. I took the photos...so I can tell you - they were coming down from the top mark on the first lap in 4th place. The mark they were aiming for was past a point that was to windward of their heading. If they had gone behind the ferry they have lost 10 places as a big pack was right behind them, as can be seen in the photo below, which was taken about 10 seconds later.
It took that pack about 1 minute to reach the spot where P&O was. cheers |

The 12 is a hard boat to handicap as the variety of rigs allow it to be at maximum speed in any breeze, where most boats are slow in the light stuff and get faster as the breeze comes in. As an example we have some older 14ft skiffs sailing with us and in the light breeze with our biggest rigs we would beat them by over 15-20 minutes in an hour race. When the breeze comes in we are only about 5-10 minutes faster. These boats would be about 20 minutes slower than a top 14ft skiff. As another comparison we raced the same course as the Flying Dutchmen fleet, which included ex World champions so were top notch and we were on average 7-8% faster around the course. |
