According to the Aussies, their latest and greatest Maritimo X60 was designed with VP D13 "engines and tankage placed forward, close to midships, to create more balanced weight distributions".
And they killed two birds with one stone, since that allowed to "eliminate the weight and expense of pod drives".
Now, all of this came courtesy of, hear, hear... STRAIGHT SHAFTS!
You can't make this stuff up! ?
In fact, I didn't - the above quotes are taken straight (pun intended!) from the boat test.

PS: I forgot to mention another remarkable result achieved, according to the test: better fuel efficiencies - I kid you not!

Is it Maratino or Amarti :) . Sound the same , feel the same with the boat split in two .....aft accommodation.

First time a builders blurb / promo stuff has I have noticed wading into
1- balance , why the tanks are fwd .
2- Aft weight ......inferring it not good ...someone’s smelt the coffee .
2- running angle < 5 degree s .
 
Sorry I just cant stop laughing. Aussies no airs and graces they blurt straight out with it .

“ Straight Shafts. Maritimo decided to use straight shafts on the Maritimo. This is a better alternative to pods as Maritimo X60 has just as much maneuverability around the docks thanks to the bow and stern thrusters. In turn, it’s a more cost-effective solution and requires less maintenance. ”

Yup J, far from defending the review as such.
But what I find remarkable is something else, i.e. the proof of what I always said:
this industry is nowadays strictly marketing driven, with very little attention to sound technical principles.
Well, not that this is unique of boatbuilding if I'm honest - Boeing springs to mind! :oops:

Anyway, let's take this boat as an example:
ALL the technical principles claimed by the builder (on whose inputs the review is clearly based) are very well known, bar none.
BUT, after deciding that a beach club could have attracted some punters also on such (relatively) small boat, they realized that by coincidence a straight shafts layout was perfect for that purpose.
So, they were faced with a dilemma, i.e. tell the truth, or use some sound technical principles and pretend that they were inspired by them.
The truth would have sounded along the lines of...
"We couldn't care less about weight balance, efficiency and so forth, but we used this layout just because it's the more effective for offering a gadget that hopefully will attract buyers".
So, it's hardly surprising to see that they went for the alternative - as per BoatTest review... ?
 
interesting remark re IPS. Were they just filling column inches or were they serious?
I was reading up on the Marex 360, that uses a shaft drive but the shaft is enclosed and they seem to be very efficient. 2mpg for a 36' boat, better than an outdrive set up.
I have wondered if a well designed shaft drive boat with enclosed shafts would be very close in efficiency to an equivalent IPS. If you put a Sharrow propellor on it you might beat IPS.

You have three options for the aft cabin in that boat. A double cabin, a beach area or a tender garage. May be you should go and check the website, then you choose which one to order.
WIth the aft cabin it become a four cabin boat which afaik none have in this size. And as always you can still put the tender on the bathing platform.

Whatever way you look at it the Maritimo X60 is a turn around product and one of the more forward thinking forward Sport Yachts in its size.
They also ride really nice and according to many much better to some other Euro products though I have not tried it myself.
This Summerl Maritimo also launched an X50 with a similar product. The X60 is selling well and I think it is over 20 units in a one year production.
Imagine if Fairline did the same some peeps would be singing that may be they will take us to Mars next year....

New Model: Maritimo X60

You are overthinking it .

Sounds like a compliment, when said from our resident Master of overthinking... :cool:

Btw, just in case you misunderstood, I wasn't implying that also Amati followed the same train of thought.
My reasoning was rather the opposite, in fact: back then, boat design used to start from the hull, so to speak.
Nowadays, it starts from all the marketing-driven features, and the hull just follows as their "container"...
 
Blimey, a shaft drive aft cabin boat. How novel. I can't help feeling its been done before though. Maybe I'm wrong

In Perth (I can only vouch for here) most people with boats this size also have a 6 - 8m rib (even up to 10m) that they tow and can then explore using that.. otherwise davits or a crane up front to lift a tender off... I don't think I have seen anyone use a tender garage here...

I saw this in the flesh at the Perth boatshow.. the rear beach club thing.. it's a good 'look at me' feature but it's just an enclosed version of the rear deck so I don't personally see the point. As an aft cabin with a view.. great... But again I would prefer the rear deck to sit on.

Still as each engine is worth more than my boat it's not like I have to trouble myself with these issues or sorting out what is marketing bs vs reality ?

To be fair to Maritimo they are trying to include less experienced boaters in their target market. They've never offered IPS in their 50ft+ boats and to the best of my knowledge they've all been straight shaft / minimal shaft angle. Their main competitor (Riviera) has embraced IPS technology to the point that virtually all their boats 60ft and under are IPS only. Therefore, it's up to Maritimo to convince buyers that they don't need IPS and that has been a theme of their advertising for many years...

They have a quality product that presents well and they're trying to be innovative with their layouts. Personally, I'd prefer the X60 with the tender garage option but at least they're giving buyers a choice.

It is not. But the four options for the aft area being it a cabin or not is original and an exception not the rule.
I actually proposed spoke about this to Itama guys in 2004, back when it was still in the hands of Bulgari, but back then they told me that negotiations with Ferretti where pretty nearly completed and in very advanced stages.

Good point.
I never had an opportunity to see a Maritimo in flesh, but a boating mate of mine who is even more fussy than myself saw one of their fisherman boats a few years ago, and he was really impressed.
So, I have no reason to ridicule their products in general, neither the X60 specifically, and in fact it wasn't my intention.
In a sense, I also sympathize with them for resisting the lure of IPS, which is yet again another marketing-driven product, but indeed capable to attract newcomers.

Otoh, some statements in that review were funny enough to make me think to relay them here.
The specific boat is kind of irrelevant, and could well have been built by another yard, anywhere on this planet.
Marketing BS is all over the place in this industry, whether we like it or not.
But at least, it's worth a good laugh, occasionally.... :cool:
 
TBH I have IPS now and dont mind if the next boat has IPS or not. If a boat is offered with the option of IPS or Shafts then you may as well go with shafts as I would have thought the hull would need to be designed with IPS in mind (as well as losing one of the selling points being that of extra cabin space). If a boat was only offered with IPS that would not put me off nor if a boat is only on shafts.
