Oh!

One could be forgiven for thinking that this blue rope had no real function at all other than maybe from stopping the fence from falling over. Some of these fences can be tricky you know!

However it is attached to the one side of the floating shock absorbing cushions and another is attached to the other side, they both being joined together in the middle. I say shock absorbing because I think they have a twofold purpose. A. to stop you hitting the bridge )which is obviously in a considerably poor state) and b. to absorb your shock that it has been like this for four years
.
22102011774This is not the only one though this might be the worst. BW do not have the funding to sort this and I think it’s a fairly certain bet that C&RT will never have the money either. So I have to wonder , “What is the plan?” Is it a case of waiting for it to fall down then dig out the canal? In the meantime are BW hoping against hope that no poor boater is under it when it collapses. Or maybe the plan is to dig a winding hole either side of the bridge so that when you come across a collapsed bridge you can turn  around. We know from past experience that some managers do subscribe to the ‘3H’ management system (that's Hope, Hoping, Hopeful)

There are 86400 seconds in a day and at the most a boat takes 5 seconds to pass under. 5/86400=17280. So there is a 1 in 17280 chance that the bridge will fall on one boat passing under the bridge and a 1 in 86400 chance of it hitting the end with someone on it, unless the female member of crew leaves the galley to sun herself on the forward sun deck at which point the risk is doubled to a 1 in 4320 chance. If 50 boats a day pass under the bridge that becomes a 1 in 345.6 chance of hitting a boat and a 1 in 1782 of hitting the end with some one on it and a 1 in 8640 chance should the crew lounge around on the sundeck, of the bridge collapsing on a boat. Nonetheless this is still an acceptable risk or they would have fixed it by now instead of wasting £40,000 on the Thrupp lift bridge and £90,000 on the mooring pontoon and barrage at Isis Lock and £200.000 on Belchers Bridge above Aynho.

Tea anyone?

Hi Maffi

An excellent piece of theory, unfortunately I doubt that BW 'management' will understand its ramifications until the bridge proves it for them!

I think you need to check out how to work out mathematical odds!

Listen carefully I will say this only once. NO I DONT. I am a writer not a mathematician. It is a semi-light hearted look at what is a serious problem. I think most people reding it would get my drift.

Hi Maffi

I wonder if your anonymous commenter is a member of BW 'management'?
