Hi. I found this picture of a Wim Van Der Valk Conti-1 randomly on the net while looking for something else. What is the story behind the radars? There must be some clever thinking here! Why are they so low?

Looks like its on a river to me, getting under bridges with the bimini folded forward and the sat mast on a hinge perhaps?

What were you looking for John. Match 3?? :):):)

Haha, one has to keep browsing boat doesn't one! The VDVs need a whole lot more kinda sex appeal though, don't they? When you look at them you sort of expect the insides to have winged armchairs in dark red velour and smell a bit of damp cats. One could be funked up though as a custom build to eliminate all that, and then you'd have a pretty swish custom boat, and beautifully made of course... :D

Ah right, yes MYAG and Rob, I see. It just hydraulics up and down by about 3 feet, by the looks of things.

Mmm, not sure I understand that. Instead of a hydraulic system to lift/lower the whole radar arch, wouldn't it have been simpler to have a hydraulic folding system for the mast on top and probably achieve a greater reduction in height? Whatever, I guess there must be a good reason

Yup, agreed. It is a bit baffling. I think MYAG's thinking was that the mast/sat dome folds as well as the arch lowering down vertically. And that the bimini folds forward, and then the whole flybridge is no higher than the 2 radars. Which are, er, quite high really... The two winglets either end of the radar arch, presumably for styling (qv...), seem to ensure that any arch in a low bridge cannot be taken advantage of :D

I guess there are no arch supported bridges in Holland:)
 
What is really hard to justify is the placement of two radomes side by side at the same height, imho.
 
Just seen this thread myself - sorry to be late in replying.

This one is much more conventional in it's placing as I hope you will all agree.
I will get Yoeri to post a techie answer for you all but as I recall this was a one off design request for the owner.
It is always the way when building fully bespoke boats as we do, the owners get what they ask for....yes, even winged arm chairs and damp cats if it is truly essential for you John.:D:D

Mike.
I have just remembered that years ago we had a request on an Atlantic 460 in build to make a third cabin specifically for the owners German Shepherd. A nice family, Dutch, of course!

Yeah agreed, that doesn't make sense either. Surely the whole point of having 2 radars is to use them simultaneously with one on short range and one on long range so they're normally mounted at different heights. When they're mounted at the same height like this, is it possible to use them simultaneously without interference? I dunno, maybe somebody can comment on that

Hmmm, it isn't always the way. A boatbuilder should , and the best ones do, draw a line at things like 2 identical radars at same height (and maybe the cat pee chairs!) if they affect the credibility of the builder/brand
 
Good comment and as one of the best boat builders, if a new owner specifically asks for something that is dangerous or plain silly we will always explain that this may not be the best idea and always offer alternatives.
Not sure that I see how 2 radars at the same height affect the credibility of the brand though?
I agree it is odd and indeed not something I would do on my own boat.
As far as I can recall this is the only one that I am aware of where such an installation has been requested. This was not a boat Imperial sold to the owner or I could answer more accurately myself but I have spoken to Yoeri and know he will be along in a while once he has checked the build folder on this boat with an update for you.

'Dunno if there's such thing as a "conventional" placement of stuff on the radar arch.
But 'fiuaskme, on that mast I would have rather used the raised position for the radome, than for the sat dome.
That choice pretty much smells of form over function...

Otoh, I love the idea of the dog cabin. Ensuite, I suppose? :D
 
MapisM are you taking the pee?:D
Being Dutch owned, the Sat dome is higher to be sure the owner gets a good signal for Top Gear I expect! It is their favourite programme over there.

There are single radars that can do that (such as my 4 YO Koden...).... dual speed and dual range ... Ie' change speed from 24 to 48 RPM and run at split screen for dual range at same refresh intervals as a 24 RPM scanner ... or run single screen/range at 48 RPM for fast vessels.

Main reason for twin installations should therefore be redundancy as the above is possible ... But as you point out Commercial vessels often have two sets where scanners are mounted at different heights, with the highest one the most powerful...
 
I'm going to throw a crazy idea out here, I suppose he now gets 360 degree visibility around the boat with his radars?

Though looking at the upward swoop on the wings of the hydraulic mast, it looks as if they are taller than the scanners?!
 
Good afternoon all,
This was indeed a custom project (initially a Continental I 24.00 meter). The owner's wish was to add a flybridge to the wheelhouse roof, which we did.

The original mast that was built on this particular Continental was a fixed "wing type" mast (see picture underneath). After 2 seasons the owner decided to raise the mast (by a local company) to an "arch" so that he could use the space under the mast as sun bed.

The second radar was requested as back-up in this case. The Furuno was installed as a stand-alone entirely separately from the general electrical system. As far as I remember it was even powered by the engine start batteries in case of the worst possible emergency.
