Ahh

OK thanks for the tip

see I always thought they curved up or something like the crudely attached paint pic

clanky · « **Reply #26 on:** April 03, 2011, 23:26:23 »

Nope, some have a dip in the top, but more modern ones tend to just be a straight cylinder behind a hemisphere.

You do know the theory behind them, right?

The Ferry Man · « **Reply #27 on:** April 03, 2011, 23:27:34 »

I know the basics...

They are believed that the bow interferes with the bow waves, reducing them, so less energy is lost through them, making the ship more efficient.

clanky · « **Reply #28 on:** April 03, 2011, 23:38:56 »

Yep, that's about it, they found that if they dragged a ball through the water so that it floated just below the surface there was a dip behind it, they figured that if they pushed a ball through the water just in front of a ship the dip would coincide with the bow wave and cancel it out, the fact that the ship no longer has to push through a bow wave reduces the power requirement and saves fuel.

And with heavy fuel oil currently at around $500 per tonne even a 1% reduction in consumption can mean a saving of $500 per day or more on a larger ship.

The Ferry Man · « **Reply #29 on:** April 03, 2011, 23:42:34 »

Ahh

Has it been actually been proven it works on ships? I am sure I read in a book that it hasn't actually been confirmed how efficient it actually is?

Although Seeing how many ships using them (Basically all of them now) there must be something...

clanky · « **Reply #30 on:** April 03, 2011, 23:50:49 »

Yeah it works, there is a balance between the increased friction due to surface area and the reduction in bow wave, but they test these things in test tanks and the results always prove that they reduce fuel consumption, I have known ships to be retro-fitted with bulbs (as well as other things like "rabbit ears" welded to the hull to improve water flow across the propellers, again all of these things are tested on models before anyone picks up a welding rod.

I'm not sure if it works for every hull form or for every planned service speed, but like you say the fact that almost all ships have them these days means it must work in most cases.

The Ferry Man · « **Reply #31 on:** April 03, 2011, 23:54:53 »

Ahh

OK thanks

Are the "rabbit ears" the same as "Duck Tail" sponsons?

Love the details on the funnel! You getting just better with your models!

Keep it up!

Thanks

You call THAT a bow visor?

That would be Berth 3 of Portsmouth

The Bilbao would block the picture if she was in it

how u do that to the pic?

The Ferry Man · « **Reply #35 on:** April 04, 2011, 09:23:41 »

I made it in Kerkythea

clanky · « **Reply #36 on:** April 04, 2011, 10:35:47 »

Looking good!

Stuart2007 · « **Reply #37 on:** April 04, 2011, 13:05:17 »

TFM, I have a 'few' photos of PO Bilbao undressed and sitting in drydock. Will PM you links.

She IS looking good, TFM. Just to avoid the doubt to anyone else on here, TFM is making a damned good model... I think the best so far. And when finished, I will be surprised if Pride of Bilbao and SSE (on one disc) does not happen.

Are you listening vstep? Don't delay the inevitable... You know it's going to happen... Pride of Bilbao is coming to a computer near you... Listen to the voice... Pride of Bilbao is coming to a computer near you... When I click my fingers you will waken up and think what a great idea it will be for Pride of Bilbao to come to a computer near you...

EDIT: Clanky, the bulbous bow actually tapers in slightly towards the bottom- makes it look squashed, but for the part of the model that (shouldn't!) won't be seen, it probably doesn't matter. I've sent Mr TFM a photo with some people standing right under the bulb. for a sense of scale.

michael_taal · « **Reply #38 on:** April 04, 2011, 13:21:03 »

looks good

ps: which program do you use?

Ralphy · « **Reply #39 on:** April 04, 2011, 16:29:02 »

He uses Google sketch up for the modeling and then uses Kerkythea to take the pictures

Looking good TFM

Look here for the actual state of the ship:

Ahh nice pics - she is looking good

Thanks for the Link Bottman

Stuart2007 · « **Reply #43 on:** April 07, 2011, 14:39:12 »

Nice? She looks great. The same Viking Line carpets still there... thankfully all the pee and ohno! tat has been removed.

Now... Can we campaign for a St Petersburg to Bilbao run via Portsmouth (in one environment)...

J3nsen · « **Reply #44 on:** April 07, 2011, 17:45:33 »

More updates NOW!!!

Just kidding around, nice work on the bow!

There are more photos now, since Bottman posted this. Now deck 2 has been photographed.

OK Small update for you:

Anyone every seen what the underwater part of her stern looks like? I have seen the bow, but not the stern...

Captain Best · « **Reply #47 on:** April 08, 2011, 22:18:49 »

It's hot

Ahh Thanks... I think...

More pics

Ask some fish

EDIT: http://www.marinetraffic.com/ais/showallphotos.aspx?mmsi=215357000#top_photo

There's a pic of her sitting on a floating dry dock.

EDIT2: TFM, you've shown a cut out on the super just below the name board. I don't remember that. I've looked at photos and can't see that either- except a shadow... Are you SURE about this?

EDIT3:
Also, you were asking for photos of the cardeck height signs.
