I couldn't agree more re. the builder which is being discussed, but it isn't fair to tar all French yards with the same brush.
Check out the following boat, frinstance.

I'd rather afford some rough stuff with one of these than with any Princess etc.

Just a white page, with the wheel which seems to keep spinning forever.
Is it a very big file maybe? I'm on a slowish line ATM.

MM, took sometime to download, it's a largish file, so grab a coffee and have a disturbing read...

I don't agree with you here. These 'contemporary' styles of which you speak will surely date quicker than the conservative 'Princess' type styling. I'll be interested to see how the boxy late model (great interior volume) Sealines will fare in say 10 to 15 years time. I think most 10 to 15 year old Princesses can be difficult to age, even when moored alongside a new one. I suspect these new Jeanneau's will age quicker. Princess appear to have the quality business properly sewn up and don't need to push the boundaries of design as hard as some - they know there'll always be customers happy to pay a quality premium. But what do I know - I own a Jeanneau!

Possibly! But one of the original selling points of IPS was that if you hit an underwater obstruction the pod would shear and you would continue to float whereas contemporary reports (there was also one on a power cat in MBY a couple of months ago) suggest that this may not necessarily be so and, therefore, that - in this respect - there may not be a benefit in having IPS instead of shafts.

actually on that issue, could it be that ONLY the cases where a boat sinks surface on the news, whereas the cases where IPS works as in breaking off leaving the hull unharmed are sinking/disappearing in the news?
do we have sucessful IPS failures cases?
cheers

Isn't that the UK social security system? Oh no, that's IDS
oi, back on track or I'll explain the Greek social security system and it's sucessful last years

Dunno, but during trials, it looks pretty convincing: http://www.youtube.com/watch?v=nLmlWgLHZAc
Would be interesting to know what hull they used for those tests.

Unfortunately, we only learn that afterwards Stupid looking original Mondeo,Sealine 35, dumb lights on Audis, Hell.. all major aritists
with mising earlobes etc...

Thanks V, yep, it did pop right after you posted your reply.
And I just had a quick read at it. Scary stuff indeed, makes one wonder how the builder can still be in business after these analyses are publicly available...
...I guess that's because most buyer of these vessels are only attracted by what they can see at a boat show - which in terms of construction, is pretty close to nothing!
Incidentally, the more I read about IPS, the more I'm convinced that it's inherently flawed.
I mean, for small and fast boats, there are outdrives and outboards.
For big planing, but not so fast boats, there are shafts.
For big fast boats, there are surface transmissions and jets.
I can't see IPS beating any of the above, in their respective segments...
...other than in the "maneuvering for dummies" scenario, that is.

I'd rather call that video ridiculous, than convincing.
All it proves is that when the IPS hits an obstacle perfectly perpendicular to the prop shafts, it works as designed.
But that's purely academic, because in any real life grounding scenario, the hitting is bound to be nowhere near that, dynamically.
Not even the hull keel is horizontal while cruising, as it is instead in that video, FFS!
In another thread, we recently spoke of how marketing BS are not so rare in the boating industry.
Well, I'd definitely put this video among one of the most shining examples!

I have to agree with this. IPS looks to be a solution to a problem that doesn't really exist. I get the close quarters steering bit, but there are more cost effective ways of achieving this. I also get the packaging bit, but stern drives do this better.

+1,
also, shouldn't they install a wire connection to the breaking off outdrive bit to the hull so that you can pick the I assume v. expensive bit and take it back to the workshop for repair refit?
Kinda like what they use to fit to F1 cars so that wheels don't end up flying about killing spectators
