The math is correct, I'm just not sure I'd count on a 870 NM range with a reserve of ELEVEN liters...

Yoeri, even if the IPS drives do return low GPH can I have mine with twin shafts?

Dear Pete,
Fitting a twin conventional drive is not a problem.
We do not necessarily have to use the IPS system, it's up to the owner.

Thanks.
Looking at your older boats, do you ever get them back for re-modelling - not just interiors but more substantial alterations to the superstructure, etc?

Goodmorning Pete,
This (re-moddeling the exterior on existing boats) happens sometimes. The question is whether it is economically interesting to do (this depends on the boat you are looking at).

and big, look at photo 3, the two guys stood talking in the hull look minute
Very impressive.

Yoeri,
What kind of time scale has passed by in your pictures so far?? The thread has been running a week but how long has it took for the hull to get to this stage??

I wasn't sure if they were "guys" or not. The pic is not so clear on my machine. If they are, it does put some perspective into the size.
Would be interesting to hear from the Fair/Prin/Sun buyers of similar sized craft if the pace of building the hull is quicker with the VdV aluminium construction, compared to GRP?

Dear all,
Thanks for the replies!
Scale of the boat
@Taz
She's big, but not that big!
In fact the distance from where the floor will be (on top of the straight horizontal trusses) of the hull until the topside of the frames is about 2.20m.
Scale of the process
@paultallett
I have posted the pics on the forum on the day I have made them. I can tell you that we have started with building at the 13th of August (just after the company's summer holidays).
In the future I will also post pics on the forum at the day I made the pics. So that you have a clear picture on the scale of the process.

Probably running ahead on the build a little, but I was just wondering on the following :
1) How well does ultrasonic anti-fouling work on an aluminium hull ?
2) VDV normally fit stabs, but from the pictures on the website I gather you also have fitted gyro's at some point.
This has been some point of debate in the past, so as you have fitted both in the past how do they compare performance wise ?

Dear newWave,
1)
Requirements for the use of ultrasonic antifouling is that you must have a solid hull: GRP, Composite, Steel or Aluminium. Because the hull shall function as a sounding board, the material from which the hull has been made should be able to conduct the sound waves well.
The system can, therefore, very good be applied to steel, aluminum and polyester (without sandwich construction) vessels.
2)
In the past, we have only applied fin stabilization.
In a ship that we will soon (about 3/4 weeks) will deliver we built our first gyro (Seakeeper M21000A system). I will keep you informed about our experiences! In about a week or 2, we testdrive this ship for the first time!

Looking forward to that.
It would be particularly interesting to hear how they compare with fins in some significant beam sea, with rather long waves.
That's where gyros are supposed to be much less effective, when they have to contrast the roll for a long period in the same direction.

Yep, I was hoping that those with more intimate knowledge of fibreglass boat building might be giving Yoeri a bit of stick.

fascinating thread/pics re the whole process.
Yoeri, I'm curious, how long did it take to built similar boats BEFORE CNC routing and plasma/laser/water/whatever/cutting was around? I guess the same design was around before that time. Cutting 4K pieces accurately on manual equipment would be a hell of a job!
Cheers

Dear Vas,
Manual cutting / sawing the boards and parts back in time took 2 guys about 2 months compared to what now is done in 1 to 2 weeks with routing. And then there are also many more parts in the package now (more frames, etc.) because of the fact they are cut out this easy.
