Van der Valk 23M in build

[Whopper]

Yeroi,

Really enjoying your build thread! Looking at the VdV website, conventional shaft drive is standard on the Continental 1 and Continental Trawler ranges. Is there a saving in cost to specify conventional shaft drives capable of pushing the boat to the same speeds as the tripple IPS set up in the Continental 2 and 3 range? I think you mentioned being able to spec shafts earlier in the thread. Do many owners opt for this?

Yoeri,

Just a thought.
Has VdV ever considered the Rolls-Royce Azipull pod drives ?
These have the option of controllable pitch propellers and that might be easier to optimize the drive setup as weight changes with the different customer demands.

 

[Bajansailor]

Yoeri, have you considered including some catamaran VdeV's in your range?

That is a mighty fine and beautiful vessel you are building in this thread, and I am following it avidly (also JFM's), and I am just thinking that a power cat version could also be a winner.

And then less arguments about stabilisers!

Naah... for comfort alone, gimme a stabilised monohull rather than a cat any day.
AOTBE, of course - particularly, speed and living space (which means shorter cat LOA).
Though from an efficiency standpoint it's hard to beat a cat, OTOH...

A connoisseur choice 'fiuaskme, but don't tell that to jfm...

Hahah! I won't tell John!

interesting thanks,
good to know, I'm quite happy with Volvo Kant Belgium,
they are close to my regular Karnic cruising area (Zeeland)
I had some words with them but at the end we still get along.

my problems where a combination of:
- bad luck
- human errors from Volvo engineers
- week design issues in the D3
- very hard and intensive usage (divers)

These are often the most annoying calls! It is often a tangle of accusations!

For what it is worth I am currently negotiating a big ship and the potential owner has recently chartered a Palmer Johnson 120 with zero speed gyro stabs fitted to it.

Hi Mike,
On the WV0100 which we delivered last September to the client we had installed a Seakeeper M21.000A. According to my colleague who slept next to it a few nights during the seatrials she is so quiet he did not even hear 1 rotation. I have to note that the Seakeeper was placed in a fully isolated/watertight machineroom. This was the first gyro we used in our ships ever, but we are very amused! She is super quiet and reduces approx. just as much side rolling as regular finns. Compared to regular finns (which will reduce approx. 80% of the side roll) the seakeeper reduces about 75% of the side roll.

Besides when for fast/planing ships it's a perfect solution (but of course more expensive) for cavitation which always comes with the bigger (zero speed ones) finns.

Thanks John! Appreciate that!
Our Continental 2 and 3 where developed for both the IPS system and a conventional drive system. In fact it is possible for a Continental I to also fit the IPS system, but we must develop the underwater again.
Funnily enough, we sell an average of 1 Continental I per year, and each time that specific customer does prefere a conventional drive in his ship.

Our Trawler is round bilged hull. Related to the deadrise, it is not possible to IPS to build in a round bilge vessel.

Dear newWave. Recently one of our potential customers asked for a Continental II 18 meter fitted with 2 Rolls-Royce Gas turbines and jet drives. But we've been never asked for the Rolls-Royce Azimuth/Azipull drives. But if I can remember they only start at a propeller diameter 1900mm. So this will be slightly to big for us. But I'm not sure whether they have developed a commercial drive until now.

Hi Bajansailor

To be honest we have never considered to build a cat for our range. But at this moment we are developing more than ever, so there might be one in the future, who knows! The only thing is that the VdV style remains recognisable!

And indeed, stabilisers are not a big issue than!

Though from an efficiency standpoint it's hard to beat a cat, OTOH...

True!

[Imperial One]

Cats have many advantages and are very popular in the Caribbean and similar warm climates. We have never sold one new or used here at Imperial and to be honest we never get asked for them either.
In the UK and Europe generally they are somewhat scarce.
Could this be something to do with the double cost of berthing that comes with two hulls?

 

[Yoeri]

Hi all,

Sorry for the short break.

Last Monday, the entire superstructure was raised on the ship.
As you can see, now the final adjustments are to be made ​​before the ship can move forward to the painting shed (mid-December).

On this picture you can really see the slot in the floor at the entrance to the saloon. No threshold will be made, but a drainage channel built into the floor to keep the whole floor on an equal level.

The windows are larger than the regular design.

Flybridge in early stage

The main saloon

Non structural partition, installed at owners request, to separate the wheelhouse from the saloon.

You can still see the narrow bars, these will soon disappear and now serve only for strength until the 2 outermost bars are completed. This creates one large window.

As you can see even aluminum smooth curves and surfaces can be made​​.

One more detail

Framework to ensure rigidity / stiffness flybridge

[CMJ]

Jaw-dropping!

It's amazing how all those sheets of Al have ended up looking like such a piece of art! Many thanks for posting and fascinating stuff!

 

[vas]

Yoeri, impressive stuff as always!

One more detail

care to elaborate a bit on the curvature with this sheet material?
I guess you do single curvature (like my plywood craft) and double curvature is a lot of cut and weld job right?
Got jigs for these curves or what?

That's going to be a pain sorting out for painting, wont it?

cheers

V.

 

[Yoeri]

Thanks for the compliment CMJ!


Hey Vas,

Thank you for your comment!

It is indeed a reasonable job to make this.

Most of the curves are indeed single curves. The more curves, the more single bends there will be. Double curvatures usually consist of several plates and welding, exactly what you say!

Yes, the plates are pressed / rolled in this curvature by using a roller press and a standing press.

Our painters are fairly accustomed to these curves (the stern part of our models is an example) but this is the most labor intensive part of the ship indeed!

Dear Vas,

I have just added a few pics of the painting process we were talking about. Mention this was another boat.

Filling and sanding

Yoeri,

From these pix, the paintwork finish looks stunning, and I guess easier to keep the gloss than with a GRP boat.

I think we covered this earlier in the thread, but what measures do you take to minimise corrosion from the inevitable bumps and scrapes?

 

[BartW]

where is this yacht going to be used,
med or colder waters ?

no need for a hi-lo swim platform ?

iirc, a few years back, I've seen a VDV at "boot" with hilo platform,
no problems fixing a Stainless steel mechanism on the alluminium hull, re electrolysis ?

Yoeri

Yoeri,

thanks for the pics, mind I never questioned the result, just that I wouldn't like to do it as there's a hell of a lot of work involved...
Spend a good 4h today to correct minor details on my f/b helm area in order to paint tomorrow and that was just an area around ONE sqm!!!
Ah, and NO curves

Congrats to all involved!

Is that red stuff called "Bondo"? Never ceases to amaze me how metal can be faired to look like the pics above. Respect!

[Bojangles]

Very impressive Yeori, amazing to see all the parts and pieces coming together to form a beautiful craft, superb use of technology and skills. That boat looks huge, looking forward to progress.

Thanks for all the replies!

Hi rafiki_,

In case the fiberglass boat is provided with a gelcoat the gloss indeed remains less longer than the way our boats are painted. The gelcoat is to be polished once every few years to get it glossy again, which is not needed with our paints.

You have made a good point! I also thought we covered it earlier in the thread, but we did not (at least not all) apparently.

The best way to prevent electrolytic corrosion (when a boat is connected to shore power arises electrolytic corrosion) while ensuring optimal safety is installing an isolation transformer (which we do). The isolation transformer transfers energy to the electrical system without direct electrical contact.

Besides we use sacrificial anodes.
The material (Aluminium, Zinc or Magnesium) of the anodes depends whether you sail on salt or brackish water.

Hi Bart,
The shown yacht will be used in Scandinavian waters and is property of a Danish client. He did not need the hydraulic platform, but most of our recent clients do need/want one!

Same as the stainless steel skin fittings (for drainage) near the waterline, we isolate the two metals electrically from each other by the use of a plastic (nylon) adapter plate. With this method we get no problems with electrolysis.

Thanks vas!
Yes I know, but I think these images are the best way to explain, right?
It is indeed a hell of a job! But even here, patience is a virtue, that is paying off! Looking forward to seeing your paintjob!

Hi Pete,
It's not "Bondo" it is a comparable product.
We use Awlfair Lightweight Surfacing Filler. It is a premium dual/two component epoxy finishing filler.

Thanks for the compliment!

Thanks Bojongles! According to the planning she (the CII 23.00 fly) will head off to the painting shed in about 2 weeks. So from that moment we will enter a brand new stage again!

Another update

Dear all,

First of all I would like to wish all of you and your loved ones a Happy New Year!!

Sorry for the delay. Last weeks we were sort of busy with most preparations for the Düsseldorf boat show 2013, so I did not have much time for taking pictures.

As you can see on the pics the complete casco (bare hull and superstructure) is now fully finished and completely welded. It took the casco builders exactly 19 weeks to finish it.
Right now, at this moment, she is based in the painting shed were she will stay for approx. 2 more months.

She will be prepared for painting by completely filling and sanding until both her hull and superstructure will be super smooth. According the schedule she will be painted at the end of February.

I will try to make some more pictures of her being in the painting shed today or tomorrow!

Wow Yoeri, 2 months for prep and paint is a huge amount of man hours and cost, assuming she is being worked on for most of that time! This is where a grp boat has such a cost advantage, as it comes out of the mould painted (gelcoat), and just needs a polish and wax.

But seriously expensive for a 1 off
