.... the race starts ~ 1715GMT. Mean 10m wind speed from GFS at 18GMT of some 20kn, and using this product ... http://www2.wetter3.de/Animation_06_...Grad/36_25.gif it looks as the gusts could be around the 40 kn mark, though I suspect this might be overdoing things. However, even at, say, 30 knots, conditions in the open areas of the River will be tricky to say the least. [BTW, quick conversion from km/hr to knots ... divide km/hr figure by 2 add the *tens* figure of that result to itself ... e.g., 80 km/hr - (divide /2) - 40 (add tens fig) -44 knots. ] Martin. -- Martin Rowley E: W: booty.org.uk |

.... indeed: however, the point was that if you are away from the
ubiquitous PC/Internet, then the conversion can be done (to a high standard of accuracy) very quickly in the head! Martin. "jochta" wrote in message ...

Ah, but if you're really smart, you don't need conversions at all. I can think in km/hr, mph, knots. Equally, I don't convert between miles and kilometres. If I'm looking at an OS map, I think kilometres. If driving, I think miles. Mind you, I once hired a car from Norwich airport with a problem odometer. Before I had even got as far as the southern outskirts of Norwich (some 6 miles perhaps), the odometer was showing about 11 units. The speedometer was fine but due to a manufacturing mistake (Friday afternoon car no doubt) the odometer obviously had been fitted with the appropriate cogs to measure kilometres. Fortunately, the hiring terms were by the day not by the "mile". I could imagine the hassle of trying to persuade the hire company that the odometer was wrong. I did tell them on returning the car but, surprise surprise, they showed no interest whatsoever. Jack |

Jack All this has reminded me of a taxi-driver friend who, when the Euro was introduced, used his speedometer to convert from Euro to Sterling and vice versa. I wouldn't be surprised to find he still does. -- Graham P Davis, Bracknell, Berks., UK. E-mail: newsman, not newsboy. "What use is happiness? It can't buy you money." [Chic Murray, 1919-85] |
