Third in the series CTT (Canot tous Temps AWB) after the Ile de Sein and the Sables d'Olonnes.

Range : 350 nm at full speed (25knts) at which speed the sound level inside is only 76db.

58' long, it has the same engines as the 46' Shannon.

The video shows clearly the pantocarene hull which reduces pitching into a head sea and enables it to maintain a high average speed.

It was in Roscoff when I was there and it really is a magnificent beast.
 
Just to remind folks :

SNSM CTT 58' 1300 hp speed 25 knts range 350nm Cost : £1.2m

RNLI - Tamar... 52' 2000 hp speed 25knts range 250nm Cost : £2.6m
..........Shannon 46’ 1300 hp speed 25knts range 250nm Cost : £2.1m

NB Big boats normally cost more...??


PS : On checkig the Shannon is 44' not 46' and the Tamar is now being quoted at £3m

Certainly looks like a purposeful and good value boat. The hull form is quite well-proven - Goodchild have been building similar pilot boats for 5 years or so.

They could have saved themselves a lot of money by paying in €. Very poor financial management - would never have happened in the RNLI.
 
They are very interesting figures I wonder just where the difference in price and performance lies. Is it down to inefficiencies in terms of the cost or construction, I don't know as for range it could be sheer weight difference or even tankage again I don't know, does anyone?

The hull design allows the boat to travel faster in heavy seas, and reduces fuel consumption. ESL are running pilot boats off the Kent coast which have Pantocarene-designed hulls. They're 17 metres long (55ft) and do 25kts. Apart from being more comfortable at sea, they have shown a saving in fuel cost of £80,000 pa per boat compared with traditional pilot boats.

Fantastic boat. The only problem is, when you're recused you get a hefty bill. The RNLI are funded on donations so hopefully will always remain free.
These French lifeboats can't be as good as the RNLI boats as French fishermen will steam into our waters to be recued by the RNLI.

Funds are mot a problem for the RNLI!

You can't beat a good forum for people making up their own stories! There is a graded pay system depending on the circumstances, yes, but you can't deny it's a good boat at a good price. RNLI executives do seem to be very well paid empire builders! ... :rolleyes:
I'm going to the Cap D'Agde boat show at the weekend, I hope they bring it down to show it off.

It was probably due to the fact that it took them 13 years between conception and delivery to bring out the Shannon. There are a lot of development costs in there which have to be allocated somewhere, but that does not mean that the boat is intrinsically better.


It took just over 3 years between conception and delivery for the French boat. That's logical when you use established architects and builders rather than trying to reinvent the wheel.

As far as performance is concerned IMHO the French boat has a much more efficient hull shape which means that the same engines which drive the 46' Shannon can drive the 58' French boat at the same top speed.

In one of the videos I previously presented they demonstrated this hull movement by measuring the vertical movement when passing through waves. The Pantocarene hull had noticebly less up and down movement compared with a conventional hull.

Here is another video which contrasts the movements of the new boat (Ile de Sein) and an existing one (Penmarc'h) in lively conditions in the Raz de Sein.

PS As PVB said - now that I have read his post...

PPS They also do jet versions which they sell to the Dutch services.

but the Shannon was designed to launch of a carriage off open beaches not lie afloat not something the French need for an ALB (the first prototype was seriously flawed, commercial hulls were trialled including the Pantocarene and Poole decided that the final in house design by a young naval architect working on his own initiative was best he is now independent with his won design company I believe,) can you confirm if there are ANY French ALB's on the Normandy and Brittany coast which cannot operate all tide

I think that the emphasis should be on the fact that it was a monstrosity of a boat carriage which was designed to launch a Shannon off a beach - a carriage which in itself costs 25% more than the French lifeboat...!!

Last year I showed an Italian designed travel lift on caterpillar tracks which I am sure could perform the same task as the Shannon carriage at a fraction of the price.

Yes the first hull showed that there was unacceptable movement in bad weather and so they spent 3 years redesigning the hull which is an evolution of the first. If the RNLI rejected the pantocarene hull they would appear to be swimming against the current because they have been accepted all over the world from the Thames Estuary to Australia. Berthon built the first Shannons before construction was brought in-house. Afterwards Berthon announced tha they would continue to produce the Shannon for other customers. I would be very interested to know how many they have sold.

I am sure that there are but I haven't spent the time to investigate. OTOH if the CROSS needs to appeal to other countries for help the other countries have a legal obligation under treaty provisions to respond. It probably works both ways because the UK no longer has the equivalent of the "Abeille" ocean tugs in UK waters.
 
You could not even show the max wind speed for your lift idea.
This has got beyond a Bee in your Bonnet, just look at the times that you have posted this stuff. You are definitely becoming obsessed.
 
Greetings.
In Norway, the Risør 2, a Colin Archer gaff ketch, RS30, of 35 tons, and over 100 years old, is still functioning as a rescue vessel. RS stands for rednungskoite, meaning emergency vessel.

She is towing me, now, from Lindesnes up the coast of Norway, as my yacht is disabled with a seized engine and bent chainplates, the result of a mishap.

If it aint broke, don't fix it..and in passing I can tell you that the Norwegian rescue service does what it says on the tin..

(if you wake up cold, wet and confused in a 3.5 to 4.5 metre swell in the Skagerrak, after your brains have been knocked out with a 200 kilo baseball bat known as the 'boom', )

Personally I'm 'still here to tell the tale', when push comes to shove you are just incredibly grateful to make it out a sticky situation. So I wouldn't quibble.
Regards Prasutigus.


Regards P
