Greenybollocks (2025 Update)

It is somewhat larger. You need to scale the emissions up for the smaller ferry or down for the larger ferry. Otherwise you are comparing apples to grapefruit.

It's still a fuckton over budget and late though due to gerrymandering politicians.

Did you expect otherwise?

Is it likely to make full use of the higher capacity? I presume a half-empty ferry uses fuel at close to the same rate as a full one?

There will be a baseload of fuel needed to move the empty ferry about and the fuel used increases with loading and the weather conditions (sailing with full load into a strong wind and tide).

The issue about size is that cars always get bigger and the increase in width means fewer cars fit on the old ferry. Capacity today of the old ferry is about 80% of when it was launched because fewer cars fit on the decks. The reduced capacity such that just one or two cancelled sailings during the busy times can result in large amounts of traffic queueing for a space. And having been to the islands outside of peak holiday season, it can be somewhat hit or miss to get a space without a booking. So the larger capacity is needed.

However, the point remains you need to ensure you compare like with like or the comparison isn't valid.

It just goes to show that calculating the contribution to global warming from all sources of emission (CO2, CH4, N2O, water vapour etc) from mining the raw materials to scrapping and recycling them at their end of life, is an almost impossible task. Results from such calculations are quite meaningless.

Perhaps they should have powered it with a nuclear reactor as per a nuclear submarine. That would really have given them something to boast about.

but it's in Scotland. There "nuclear" means 'bombs'.

Well it was the Dearly Departed and Wee Krankie who were running the show, so, business as usual.

It will come, because it has to. But a sealed small reactor isn't here yet. You only need a couple of MW.

-- If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the political, economic and/or military consequences of the lie. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State.

That is not so small.

Savanna and the US aircraft carriers are bigger ships than a ferry

It should have been run on peat. Several dozen cruachs would have been enough per trip.

The best politicians can do is not make things worse than they already are.

The latest delay was the noncompliant anchor . I heard to save weight, it was made out of polythene.

Possibly they should have said b%%ger it and tried to refloat the old Glen Sannox, I was sad to see this having done the Arran trip on it countless times.

On a worse note Hogmanay has been cancelled here in Edinburgh . I blame the SNP, Brexit , Putin or whatever,

That should be the saying of 2025, it is so true and important.

Doctors have the Hippocratic oath with its "first do no harm" principle.

MPs could have the hypocritic oath "first do not make things worse than they already are".

Happy New Year to all!

The Arran route is a busy one so I imagine they commissioned a greater capacity vessel due to greater demand.

It's a vessel with a 41% increased capacity with only a 35% increse in emissions so I fail to see the justification for the knee jerk negative reaction from the o/p.

Golly. That will really save the planet wont it?

With some lateral thinking they could have come up with a chain ferry - leave the power source on land.

The Firth of Clyde is a major shipping route. A 25km chain could be quite a hazard

Don't chain ferries usually still have the power on board, just pull themselves along the chain?

Pulling the ferry across from the land side must be more difficult with one side pulling in and the other paying out lots of wet cable or chain.

nib

And you would need twice as much cable/chain to do it that way :-/

And the chain / cable rises up from the sea or riverbed to the ferry and drops down again after it as it pulls itself along so other vessels can pass over the chain though not too closely. NPs idea of having the power plant on shore and pulling the ferry would see a taught line 25km long at its fullest extent . Thats a lot of drag and weight to haul , what would 25km of chain strong enough to do that weigh ? Possibly more than a ferry of a suitable size for the traffic to support.

Chains that get wound around the shaft mechanism on the chain ferries because of the environment of being in sea water and picking up material from the sea bed wear out fairly quickly and one dragged onto land would be pulled in the same environment so would likely wear as well.

The ones on the Sandbanks Ferry across the entrance to Poole Harbour need replacing about every 18 months. at around £70.000 for a crossing around
