Hi Tuomas, if it is rust between the glass and the window sill. it is quite serious because rust tends to expand the metal and eventually cracks the glass, we have seen it happen similarly on windows in homes and mind you these domestic windows are not subject to salty water.

It could also be poor workmanship during the surface treatment and coating phase, something that is not apparent while the ship is still at the yard.

Yes jaybird, that could be another reason of the rust emerging on those window sills, though blowing up the picture I have not seen any hot steam outlets, could be they are very small and not discerned if not close up? To keep those slanting windows salt free is a problem without any mechanical help such as electric wipers.

Could be off her steam outlet's getting a bit too hot making the paint flake off

Yes I think so Brett, they sure look like rust, if not rust I cannot imagine what those stains/marks are. On those sloping windows sills,seawater and salt accumulates.

Do I see rust already on the front windows and rust stains ????

Re the link on the OCEAN EXPLORER, the link is very informative especially the main photo showing her underwater hull, Thanks andrecas, take care my friend.

The first cruise ship with the X-bow was to my knowledge the GREG MORTIMER of the so-called Infinity class, see:
http://www.shipspotting.com/gallery/photo.php?lid=3153790
There the designers did not dare to install the large windows in the front, which are really a threat in case the bow goes through a wave, which seem to be more probable with this design.

Given that some of you have been wondering what I think, it would be rude not to respond. Firstly, they are very good pictures, especially the profile view. The stern really makes her look like a supply ship of some kind but this must have been what the design is based on given that she is some form of 'soft adventure'- type cruise ship. OK, those are the positive thoughts, basically I think she is very ugly.

The same long-know hydrodynamic principles but a completely different application - both benefit from reduced power needs/greater speed. But the low freeboard of those inverted-bow warships produced very wet decks just where the principle armaments are. On the contrary, the modern X-bow reduces spray, and the "ride" is smoother (reduced slamming and vibration).

For cruise-goers, forward-facing observation areas without the constant risk of water on the lens are going to be popular (doesn't reduce wind or rain though). Emmanuel is right - this is here to stay.

Battleships built before the first WW had similar bows... In other words: Its not a new invention of the supply boat designers

For the very first time I saw this ancient Greek ship bow on a Norwegian supply tug about ten years ago

@ Emmanuel.L....Following link contains information on this X-Bow design vessel...

Has anyone got more info on this futuristic looking cruise liner, like where she was built , tonnage ,engines, number of passengers etc...

Am keeping out of this one what i think my mouth is zipped shut !!! only 10/10 Emmanuel for the photographs all the best !

Like her or not,we will be seeing more of this bow design on cruise liners in the future ....everyone asking about Clive reaction !! I wonder what his remarks would be like. Personally for me it looks a bit strange, just like seeing her bum instead of her bow....but who pays the fiddler calls the tune, her owners must have made serious considerations re her appearance and performance.
regards to all

Would not mind sitting up front...things change...Clive will get there... ?

Awaiting Clive_

I can't beat the thought that I'm looking at her stern than a bow!

I mean, Disney's cruise ship have such sterns, for example, so?

You can see that on the supply ships. It takes getting used to. But I prefer the old form.

We are looking at the future of ship design, especially the bow.

Out of the ordinary!
