IPS Drives - Vote

Re: Airbags/recovery lanyards

I think some of you may be missing the point.

I don't really have much of an opinion on this stuff because it's not relevant to my type of boating. However, I am unfortunately one of those early adopter types so if I was interested this is the sort of thing I'd typically jump at it. (I think it's brilliant!). My view would certainly be that I believe the shearing of the drive would only happen in the same circumstances that a Shaft Drive would be trashed.

This would lead me to draw the following conclusions (based on no knowledge at all mind).

It strikes me that if the prop is DESIGNED to shear off in the event of a collision then the replacement/repair should be quite simple.

If the same happened on a shaft drive you've got all sorts of stuff to sort out because the smash/break would be unique. In theory, if the prop breaks off on IPS it always breaks off the same way, same place and causes the same re-install issues which would certainly not be the case with a shaft drive. Result should be:
- back in the water quicker
- less hassle
- no need for any other specialists to be involved (ie GRP fixers)
- No Survey required (for insurance purposes)
- Any Volvo dealer can make the fix
- Because it's a consistent fix more people know how to deal with it
- Although expensive, there would be real justification in carrying a spare

- God forbid maybe even cheaper!!

All IMHO (of course) - I may be over simplifying this I know

Re: Airbags/recovery lanyards

Ooh no! A single prop can only wind a rope one way, but duoprops can make a real bugger's muddle of it.

Re: Airbags/recovery lanyards

Lets face it, it's just a ploy by Volsplutter to grab the one bit of market they dont have and turn a hundred quid prop shaft into a mega money parts replacement zone with even more opertunities for profit as the bits fall off. Dont doubt it works, well thats if it dont break like the last four V**** gearboxes I've had. It will doubtlessly be designed to fall to bits the nanosecond that the guarantee runs out and even then, only applying with the mandentary Vsplutter oil, Vsplutter mechanic and Vsplutter small print.

No, I'll stick with the little man down the road with a lathe to make the shaft and just about anyone else for the prop.

Lift n Legs 10K.On a Volvo invoice near you soon?

A.Cost of 6 ft of stainless steel shaft + basic P bracket and prop.All available from just about anywhere and from just about everywhere.(Well nearly)
B.Cost of drive leg.Available only from one source and dont think that most dealers will stock one 'just in case". /forums/images/graemlins/smile.gif.
What happens if you ever need to dry out or ever gently run ground,with any other boat ever made you can just wait for the tide to flow again and off you go.All you would suffer from is dented pride,with this system you will look forward to your tow home followed by your 10k(min) bill.Lift n Legs.Ouch.

Re: Lift n Legs 10K.On a Volvo invoice near you soon?

No. A bit OTT. I cant run my boat aground. But I would probably get away with a few hundred and maybe a tow home.

Yes, but you forgot to add the cost of pumping out the boat to refloat it, hull repairs and a complete refurbishment of the interior if you you hit something , in a shaftdriven boat, with sufficient force that had it been an IPS system it would have sheered a leg off

Re: Lift n Legs 10K.On a Volvo invoice near you soon?

But we have yet to see the proof of that yet. I only ever nearly sunk a boat because of Volsplutter outdrive failier. What makes me think this is any better!!

IPS

Shame, that some here on this thread are talking total bollocks.

The IPS system is as good as its going to get for many many years to come.

IPS (inboard performance system)

'CHANGING BOATING FOREVER' Thats what the press are saying.....

Car like manoeuvring gives easy docking & perfect high speed handling. Minimal vibrations & sound, virtually no exhaust fumes. Onboard comfort takes a giant leap forword.

Developed & manufactured by one company, Volvo Penta. IPS is built with safety, reliability and care for the environment in mind, lower service requirements. 10,000's hours worth of development and testing, infact since 1998 when the concept was first penned...

IPS offers approx 35% greater efficiency over shaft style inboard instillations. Reasons, counter-rotating propellers working in undisturbed water, completely horizontal thrust. ie- All the force driving the boat forward!!!!!!

Figures, not unrealistic.....

20% higher top speed, 15% faster acceleration, 30% reduced fuel consumption, greater cruising range, 50% better turning radius, up to 50% lower perceived sound levels. Christ!!!!! What more can you ask for??!!!??

Deal with it people, its coming to the leisure marine industry, like it or not....

Re: IPS

Now I accept that my drawing might not be excactly to scale and might need some refinements. But if the propshafts were to prutrude folwards, they could be more or less straight especialy when we concider the bows will be raised. I reccon that Volsplutter have made an own goal. The much more modern MFFP System will render the Volsplutter an expencive, redundant option.

That's what should make us - at least - a bit suspicious.
Let's wait to see new fishing boats equipped with it, then we will talk.

Re: its coming to the LEISURE marine industry

MapisM.... Which bit didn't you read!!??? /forums/images/graemlins/confused.gif

The IPS is only intended, designed for twin installations in planing boats from about 35 to 50 feet with hull design top speeds from 25 to 45 knots.

Guessing that counts out your fishing boats!!!!!!!!!!!!!!!!

Like I said...

IPS, its coming to the LEISURE marine industry. Not commercial, get it???

 

[apollo]

Re: its coming to the LEISURE marine industry

Yep, the Commercial operators would never buy it!

 

[MapisM]

Re: its coming to the LEISURE marine industry

OK, obviously the term "fishing boat" was not accurate enough.
BTW, I should have thought about the possible misunderstanding: my boat is exactly what you're probably thinking about: almost 40 tons of woods, trawling around at 9 knots or so - unsurprisingly, its builder started with "real" fishing boats... /forums/images/graemlins/grin.gif

But in this case, Bertram/Hatteras style boats are what I was thinking about.
And many of these boats - though built for leisure - are actually commercially operated.
Ever been in Ft.Lauderdale, or any other US marina?
Besides, there are other type of boats which are specifically made for commercial operations (i.e. daily cruises): planing hulls, 40-50' size.

Now, let's forget all the other benefits which you mention.
The "30% reduced fuel consumption" alone should be sufficient to make all these commercially-minded operators sell their current boats and buy new ones with IPS.

So, like I also said (just rephrased a bit... /forums/images/graemlins/wink.gif)
Let's wait to see professional operators using boats equipped with it, then we will talk.

 

[MapisM]

Re: its coming to the LEISURE marine industry

Well, in spite of appearances, I am not 100% sure about that.
If IPS is really that good, commercial operators will consider it. They're more open-minded than we might think...
But for sure, they are also much more driven by facts - particularly with regard to costs and reliability - than leisure boaters, who tend to be more "magazine-driven" (or even worse, "fashion-driven").
That's why, whenever I have the opportunity, I ask the viewpoint of professional working - not playing - at sea.
Any equipment which works for them, is automatically in my "approved items" list.
BTW, I am generally interested in trying new hi-tech toys. But not when boating.
With regard to IPS, time will tell, I'd just let someone else be the guinea-pig.

Re: its coming to the LEISURE marine industry

You're wasting your time then. It was never meant as an industral bit of kit, and can't imagine why you'd think otherwise unless trolling
