I have read the reference to the weight of CC as 110,00 tons (or thereabouts) many times over the last week. It is a bit misleading. Actually the gross tonnage is 114,500 tons (from memory) which as you know is a hypothetical value based on calculated volume. The displacement is I think (again from memory) ~54,000 tons (not sure if that's loaded or not). This is just for clarity Ken. Not a criticism at all.

That would certainly be a "loaded" figure, given that the draft is a little over 8 metres.

Tell that to Capt Evans, Toad

Then as I say it's stupid law. It either makes an unreasonable requirement on people or fails to indicate what they are required to do.

A textbook bad law.

No, merely the rather unequivoical Italian legal statement of the tradition of the Capt 'going down with his ship' pour encourager les autres/ fainted hearted/cowards/ armchair commentators:D

Simples, you stay with your boat until all your crew are off/safe,or it sinks/burns under you, then you look to yourself.Step up into a liferaft, not fall into one.:rolleyes:

Something I had drummed into me from age 8 upwards-
It's the downside of real command, Toad, not fashionable I know, but there you are, deal with it;
The survival of the boat, the survival of your crew, your own survival-
The Birkenhead Drill tradition, if you like; something most of us aspire to/ manage(d) to emulate when the time(s) comes ashore or afloat.:(

VicS,

not sure what you mean; personally I prefer, if travelling parallel to a coastline, to keep a decent distance off and save any bragging for the club bar.

Ooh it's a very long time since I did that as blind pilotage officer on various black war canoes. I thought but it is so long ago I may be wrong that Parallel indexing only works with a noth up display and in many areas head up was the norm.

It is a bit like when we had a USN rider with us and he was very surprised and impressed by a method of contact plotting we used (peculiar to submarines as it was bearing only) and took the details back to the US to introduce the concept to the USN submarine force. Without a system for exchanging ideas they stay where they are.

North up, relative motion, yes. But a ship has two radars, if not three.

For non-radar users - the point of it is that it alerts you to cross track error.

In daylight one could add a distance off by vertical sextant angle au Lecky's Tables.

At least, a British ship would use parallel indexing - I was staggered a few years back to find that it was not taught in Norway... dunno if it is now - it was only invented in 1957 so one must allow them time to catch up... :(

Lecky's Tables, that goes back a bit, nigh on impossible to get hold of a copy of them now.

Noggy pilots in Stavanger have been known to use PI

Ta for that.

Good tip, Minn- we mostly use radar head up for x TSS/Col avoidance n GPS for nav- no overlay poss on current stand alone systems.

Worth practicing doing for West Country/Brittany in fog, instead of just relying on DR n GPS plots?

I doubt that any passage plan with a flyby near any hazard would be approved...

Costa approved the flyby in Aug 2011..who else has to approve of it?
A plan is a plan if it exists, however flawed.

It could be proved there was an unwritten plan if it had been discussed by the officers and they testified to it, or it was recorded in the bridge.

If Costa approved a sail past passage plan in August, January's attempt didn't conform to it.

Two thoughts today:
BBC news this morning had a recording of the crew announcing over the speakers that there was no emergency, they were fixing the generators, and everything was under control; passengers are advised to go back to their cabins.
This was after the ship had grounded, and the passengers were at the muster stations with their lifejackets!
Sky News last night had a fairly convincing GPS track of the vessel after the initial strike. The ship lost way and stopped; the ship's bow then came round to starboard, and she slowly rotated 180 degrees, meanwhile drifting slowly towards the island. To me, it looks like the only propulsion available was from the bow thruster, plus just possibly a stern thruster later on. Anyone know if she had the latter?

I'm still intrigued by the suggestion that someone - Captain or First Officer ? - dropped the port anchor & span her around to face the shore & ground her; nice idea but seems to me they didn't have time for an evolution like that to ready the foredeck crew, but it was quoted by someone, no doubt trying to sound heroic / save his professional seagoing arse....

If there was power to the bow thruster that sounds more likely ?

Demonstrably the attempt in jan wasn't quite the same path in detail, and the rocks can testify to that, but the purpose of the plan was the same as that of the Aug 2011 Flyby though, to go close to the island and impress. So the plan itself may have been approved, if not its use on this occasion, and it certainly involved going closer to a haxard than needed.

I recall that (according to the press, prob BBC) Costa themselves acknowledged their agreement to the Aug 11 Flyby plan for the local festival (but I'd have to find the link that said so).

Here is the excellent AIS animation on Sky:

The final approach to the island was done slowly and sideways, which suggests use of bow and stern thrusters. Quite impressive actually...

Thats the best and probably most correct animation I've seen so far. Yes, if their intention was to beach the boat as close to the port of Giglio as possible, they did very well if they were using bow and stern thrusters only. But it would be interesting to know in what direction the wind and tide were running at that particular time because I don't think turning the ship around and beaching her in this position would have been possible without either forward power or the assistance of wind/tide

Wind and tide

I believe there is negligible tide in this part of the Med but there's a slight N-going current. The conditions were reported as calm and visibility good.

I don't see that the skipper can be criticised too much for that. Most likely he did not know the extent of the damage after the groundings and possibly first reports from the engine room may not have indicated the true extent of the damage. IMHO its highly unlikely that he or any other officer would have ordered passengers back to their cabins knowing that the ship was badly holed and sinking

Well then they did well to shift the vessel against the current and beach her close to the port on thrusters alone, if that was the case

Exactly how do 'thrusters' propel the ship forward ? I think they only work laterally, unlike much smaller boats where some bow thrusters can give forward propulsion.

This is referring to 'thrusters' on a liner, not the Starship Enterprise !
