i've been on a crash diet since mid january and have to date lost 4st , but i was wondering what should i be aiming for really ?

You have got to be the bravest man in the HCGB to ask that question here. If you 21 stone you've got a way to go, If you were 9 stone I suggest you stop now. http://hovercraft.org.uk/images/icons/smiley_icons/icon_razz.gif

Hey Daz,

Go to your favorite shipchandler, buy yourself one of those " bank -o - meter " designed for sail boats.

Glue it on your craft as to measure longitudinale incline.

Get on your craft, start engine, and go......

On the small scale from 5 up to 5 down,

if you read between 1 and 4 nose up, you have a good weight,

if you read 5 or more, take a spare gas tank with you and put it in front.

if you read 2 nose down or worse....... WOOOOP ! WOOOOOP ! WOOOOP ! WARNING !

idle slowly, go back to the paddock, cut engine and :

either: - start a diet

- start scale modeling

- sell your craft

- buy a bigger craft

- finaly, a Zodiac could be nice....

- never come to the french Raid

Hi Daz



I'm on the weight loss program myself - check your body mass index - aim for 25 or under - mine's 26.9 and falling - should make 25 before the first race



you need enough weight to keep the craft on the ground, people under 10st seem to flip often - eh Rupert!

Hi, Tony.

I've checked out that BMI reading and according to it I'm not overweight, but must grow another 2 inches.

i agree it is impressive but its also VERY hard work , i've checked out my bmi already tony and according to that need to be 11st to be classed as health , now im no expert but i think i'd dont think it takes into account your body frame etc



now im really unsure of what to aim for http://hovercraft.org.uk/images/icons/smiley_icons/icon_confused.gif

hey! Some men are never happy with their weight! like... http://hovercraft.org.uk/images/icons/smiley_icons/icon_confused.gif

umm wrestlers, or body builders!

hmmm i am still not sure but i must forgive you as you are good at Gully Hopping and i shall be hassling you to take me at Blackwater in a few weeks time!

Y is it that guys can get as big as they like and chicks have to stay small, I say that guys need to get into shape and stay like that, we cant expect that the wimmen take care of themselves and we just plonk around like jelly fish..



Cum on guys, get that heart pumpin and them legs a going and get fit, set a great example for all the wimmen out there. http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif

I strongly disagree.



If you're thin, you race F3.

Average weight, race F2

Fat Boy Club - Go F1.



ie if you get bigger, get a bigger engine.



Simple. http://hovercraft.org.uk/images/icons/smiley_icons/icon_smile.gif

I did actually do some theoretical work on this once. You can use partial differential equations to work out the effect of driver weight on race times.



What I found was that wearing body armour adds about 0.3% to the lap time.



That's based on a F3 inland race and I chose to keep wearing the armour. Obviously, for other situations the numbers will be different. I imagine in some of the coastal races one could take a picnic basket along without much effect.

I also did some research (and am in fact still undersgoing regular study before i feel ready to start analysing the results)



Without getting too technical, I've discovered that if i eat enough doughnuts - I get fat.



I understand that there is a documentary series shown on Television most nights which addresses a similar issue. It's called 'The Simpsons' or something.

http://hovercraft.org.uk/images/icons/smiley_icons/icon_rolleyes.gif F=ma (Force = Mass x Acceleration)



http://hovercraft.org.uk/images/icons/smiley_icons/icon_rolleyes.gif therefore if mass is reduced then for the same force (fan thrust) acceleration will increase



http://hovercraft.org.uk/images/icons/smiley_icons/icon_rolleyes.gif therefore



Less doughnuts = more acceleration



The maths proves your theory Russ - i think you're onto something here http://hovercraft.org.uk/images/icons/smiley_icons/icon_eek.gif

OK so F = m x a

and so acceleration = F / m



Lets say the weight of the craft is 125kg

Lets say the driver ways 75kg (around 12 stone), but then goes on a diet and loses 1 stone (6.4kg).



The increase in acceleration due to his diet is 6.4/200



So losing one stone in weight gives you a 3.2% improvement in acceleration.



So you need a pretty dramatic weight loss to achieve anything worth while - although every little helps. Well done Daz for losing 4st - but I think I'll stick with coming last and enjoying the pizzas!

thanks richard , well as you knew what i looked like before the diet i think it was a case of too many pizza's that got me in that trouble , anyway its almost 4.5st off now .......should make the craft lift alittle easier anyway .....i hope ! still more to come off tho so i'll keep going for now i think http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif

Last year i lost 10Kg purely by changing what i eat. I ended up eating more, but healthier, and that was without excersise. So ya can actually lose a fair bit without the extra effort of excersise http://hovercraft.org.uk/images/icons/smiley_icons/icon_surprised.gif

Since working out the balance point of my craft i've lost 10Kg and my wife has lost 15kg, no wonder i have to sit further forward in the craft now when crusing http://hovercraft.org.uk/images/icons/smiley_icons/icon_razz.gif
