Air movement to wind and sails are way different and much more complicated, because you have to take in count the reaction of the forces applied on the keel. Not forgetting that the sails work like a wing, intrados and extrados, and that the jib influences the main sail…*That's why some boats can go faster than the wind.

I once joined a "peloton" of my local club riders around Castle Combe Circuit, I could keep up with the group in the slipstream but when it became my turn to take the lead I couldn't ride fast enough to get to the front Sent from my AC2003 using Tapatalk |

Did mostly the motor racing circuits with a gearbox class . Slipstreaming was quite important , even with our very low profile . Depending on various factors , we could pick up a tow from 10 to 20 yds behind . You would feel it suddenly getting faster , close up on the one in front , back off the throttle until the right amount before the next corner , then full power would slingshot you past . Then someone had the bright idea of closing up until you touched their rear bumper , [ only with someone you could trust ], then full power again and the both of you could go far quicker together than possible just by yourself . This had some quite amazing effects until the RAC/MSA/ MSUK decided that pushing at 120 to 150 MPH was not considered safe so they put a ban on it . But it was fun for a time . |

It's exactly why the nose cones of karts these days incorporate a special clamp so that when you "persuade" someone to go faster it slides inwards. At the end of the race any driver with the front fairing not properly lined up gets a five second penalty which cannot be appealed.
What used to happen in the rolling starts was that the whole grid loaded the kart ahead resulting in the front row ending up in the tyres at turn 1! Sent from my AC2003 using Tapatalk |

Assuming it can only slide once, five seconds is the total of penalty. Does this persuade your drivers to push a lot of times? Once is five seconds, ten times five seconds, push once and get nine free sounds like bargain.

Yes that's what tends to happen, nose cone drops and it's "sod it, need to find five seconds". Either that or the side pods get used a lot more.
To be honest kart racing is so close in the pack that you can't gain five seconds back. One time MiniMM was 0.3 seconds off fastest lap and it was 22nd quickest! Sent from my AC2003 using Tapatalk |

Phew, this is close racing! Just out of my curiosity, how tall is "mini" MM?

"R" scent was great but could this oil increase the octane level? Using it in a four-stroke was quite a hassle if I remember well.
I wonder what kind of vegetable can imitate the castor smell… Jamaican? |

Except possibly Cadwell Park which sometimes had rolling starts , and with a normal 50 on the grid it did get very busy for the first lap or two. But generally a clutch start would give less congestion in the first few corners . |

Funny you say that, I'm 1.89, Zef Jr, last time we went karting was 1.78, and 20kg lighter, and getting faster. I'm still a few inches above, but he's catching me up in every respect.

I'm signed up for petrol price alerts, and have noticed that since Christmas the price of unleaded has been slowly creeping upwards, and is now about 6 pence more a litre than it was, after the price had remained static for many weeks.
Being a curious soul, I googled why the price was rising as world prospects in the immediate future don't look all that rosy due to the pandemic, although things are bound to improve during the summer in the northern hemisphere. According to a number of websites, it would appear that many dealers and hedge funds have become very bullish about the future, and have therefore been buying forward vast quantities of oil and derivatives, thereby pushing up the price. As these people, when they do something like this in tandem, rarely get it wrong, seem to be optimistic about the future, one must be encouraged that we may be able to turn the corner fairly shortly. |

For Bauble, re the jab.
According to Dr Phil Hammond, writing in the latest issue of Private Eye, he was given his vaccination at work in his hospital. He experienced mild side effects which he states is a good sign that the immune system has responded to the vaccine. However, his and his colleagues' side effects all passed within 48 hours; the side effects tended to be worse for those that had already had Covid-19. |

I have seen a US medic suggest the responses to his second jab were more noticeable than the first, though not especially significant for a person of his age (about 40 I would estimate.) |
