Today I have just returned from a nice new year break.
On our journey home I only saw 3 caravans being towed........ they pasted me doing at least 70 MPH !
I was plodding along at 60 MPH , agreed the conditions were good however I wish fellow tuggers would slow down .

It is the kinetic energy that is really worrying as speed increases. The formula is multiply half the mass (weight) by the square of the speed.
So if the speed is 50 units then its contribution to the energy calculation is 250, if the speed is 60 units then the contribution is 360. That is more or less half as much again for an increase in the speed of 20%. For 70 speed units the contribution is 490, so the energy in the moving object is twice what it is at 50 units.
All that energy has to go somewhere when something goes wrong!

Towing at more than 60 mph increases the chances of getting to site before those that have taken the time to meticulously plan on arriving at bang on the designated arrival time. This gives a greater opportunity to select the very best pitch with the correct sun aspect, distance from the toilet block, the best possible view from your front window and only having a neighbour to one side of your van. Safety of others can DO ONE!!! All of the above is way more important.

Posted on 05/01/2017 20:57 by EmilysDadI did the sums to see whether my maths was the same .... not to check your maths ....
70mph divide by 60 = 1.1666 miles per min
1.1666miles per min x 1760 x 3 = 6160 ft per min divide by 60 = 102.6666 ft per sec
Those are my working in the margin
.....
but as you say, what are a few feet per sec between friends?

Just to extend this a bit further, if my maths are correct, the time difference in driving 10 miles at 70 compared with 60mph would be 1.38 minutes (98 seconds). Is it really worth the extra stress and increased fuel consumption by driving above the legal limit just to save this tiny amount of time? Even on a 100 mile journey the time saved would be less than a quarter of an hour and that is only if you could maintain a constant 70mph for the whole journey
