My new project... MFV Elizmor

Preston Marina have said as much.

Not that I can be bothered to find their posting(s) now...

The closest I can find is this:

“So why can't you use that information?”

For the same reason that, although your MOT cert says your car was OK at the time of testing, the guy that tested it doesn't have to vouch for its condition for the following year. The same guys would probably come and re-test the ground specifically for Elizmor, but their bill will have to be paid of course.

So it sounds as if it's not "obvious" to the professionals.
 
You put a 35 tonne boat on a lowloader and see what happens....

I wonder how British Rail work out ground loads for all their track? Extract of weights involved-
locomotives are anywhere from 100 tons to about 250 tons
box cars loaded about 90 tons
covered hoppers and open top hoppers loaded 130 tons
and flat cars any where from 50 tons loaded to 200+ loaded

The weight is spread on sleepers but the cranes outriggers can be put on huge pads.

When a locomotive went off the track on the Inverness - Kyle line last year, they decided that the trackbed couldn't take a big enough crane to recover it to they scrapped it in situ. Since that decision cost them a milion-quid locomotive (c.f. million quid cranes) I suspect it was taken by qualified experts and not by good cheps saying "Well, it's obvious, isn't it, old boy?"

But will we ever know if the expert was right ? or did he blow a million and no one called his/her bluff ?

Well exactly. That's why Preston Marina should simply lift a series of increasingly large weights until the quay collapses, then rebuild it and launch Elizmor if she's within spec.

The weights? Oh, bring 'em in on a low-loader.

My recent experience on "experts" i needed a large but not that heavy boat cradle moving from Cornwall to Cambridge, the first quote was we will need a crane and flat bed truck, I questioned this, the 2nd quote was a flat bed and a four man lift.............i questioned this....... a sprinter and two men was all that was needed. At what point should I have thrown in the towel to the experts ?

When you found some? Sounds like you were dealing with blokes who think they know what's obvious.

You honestly needed all these people to tell you it would fit in a sprinter? You do need expert help but only with the obvious FFS! :ambivalence:

I outsourced the lift, the first two "experts" tried to quote what it needed and the associated cost's, if i didn't know otherwise i would have been left with no option but to pay one of the quotes but previously (Reference to the big boat in the "My Big Project Thread") someone had moved the cradle without a crane, without 4 men (and a ground survey that they walked on) before (just like the big boats in the marina) and we managed to do it again ( without a quay collapsing) for reasonable money.......:o
