What is that ARTR Yacht in this months MM?
« on: March 30, 2009, 03:39:14 PM »

Can anyone advise the name and manufacturer of the ARTR Yacht, the Volvo round the world racer, that is in this months MM mag? It looks quite good and i fancy getting one.

Cheers,

Charlie

That does look pretty darn smart, doesn't it?

Mind you, those dagger board thingies that they lower on the leeward side (I think......) don't look clever sticking up above the deck. And they don't operate on the model, so they are both in the up position all the time.

Wish I understood the theory of them, but  if they work I expect we'll start seeing them on IOMs soon, until they get banned of course.  ok2

The dagger boards are used when the keel is canted out to windward to reduce the leeway as the keel gets effectively shorter. On some of the proto Mini Transat boats, they have one canting dagger board just to make things complicated.
So not really much use unless you have a canting keel.

The boats look quite nice from a sports boat point of view, be interesting to see how they sail.

Looks nice, it certainly will give the fish a fright with all those bright orange appendages bearing down on them !  :}

Richard,

Thanks for that, I see what they're meant to do now.

On the pics you've posted, is that first one a model? It's got no crew and the sails, mast and booms etc look model scale, but the water looks 'full size'. Perhaps it's a BIG model!  :-)

And I'm assuming that the second pair show the CML boat, and one pic shows the dagger board down. The MMI article seems to intimate that they don't actually work, but it looks as if they do.

Both the pics are from the CML site, I think a bit of "artistic license" in the first one with the sea background.

I haven't seen the MMI article so wouldn't mind a scan if possible or I'll go and have a look in the local newsagent and see if I can find a copy

Managed to find a copy of MMI and read the review today.
Sounds like it could be a nice boat but I'm not too sure why the reviewer kept referring to the dagger boards as stabilisers and then going on to give a completely wrong description of what they are and why they're used. He also spoke about water ballast which was applicable to the last type of boat not the one represented here.

In a sort of 'what goes around, comes around' thingie I bought the actual Model Boats review model of this Volvo Open 70 while I was at the Weymouth Festival this weekend, urged on by my wife no less! She got very enthusiastic about the orange/black colour scheme and reckons it looks really good.

I didn't have a chance to sail the model at Weymouth but after a bit of fettling at home took her down to my local lake here this morning and had about 20 mins on the water before more water started to fall on us from above! Piccies below and as you can see the extra daggerboards weren't installed on the model. Looking at the 2nd pic perhaps I should have used some.....  :-)

She sails pretty well but the mainsail needs some adjustment to make it work well, it's far too loose footed at present, but I'm working on it.

Daz,

Only when your mate (who's a died in the wool powerboat skipper) is at the helm and asks 'What do I do now?' as he hauls the main sheet in, while under the impression he's 'throttling back'........  {-)

She looks to be a little under balasted, like most ARTRs

The ballast weight is about the same mass as the ETNZ yacht, but the fin is quite a bit shorter, perhaps 2-3". All that helps to miss the shallows in my local lake, but doesn't keep the boat all that upright in the squalls, which are legion with the wind from some directions, as it was that day.

I'm going to re-rig the mainsail and adjust the Tx, as the winch servo is very sensitive as supplied, then see if that improves things.

Probably, but that's SERIOUS engineering. Or it would be for me anyway, so that would be my last desperate step.  :-)

Hi kitS

Did you get any problem with the yacht shipping water through the underwater ports where the dagger boards go through?

Yours aye

Jumper,

No, not at all.

The dagger board access holes are plain slots that go clean through the hull and out the bottom with no access to the interior, so the water can't go anywhere apart from into the slot. I suspect that will be causing some un-needed drag and I may fill the bottom of the slots with filler later on. Anything for that last 0.000001 knot.   ok2

Mmmmmm

Must be going blind in my old age - Just looked at my one again and I now see that the slots go all the way through the hull.

Next question, where is all the wet stuff coming from? - will float test it in the bath.

Aye

The most common places for water to get in, that I can think of, are:


No.1 - Through the hatch. This happens when the deck is awash, either heeled over or on choppy water.

No. 2 - Through the keel tube or rudder tube, if they are not glued fully home. Sometimes the glue cracks. This could also apply to the fin slots, where the joind at deckand hull with this model.

No. 3 -Minute cracks in the hull around the keel slot in the bottom of the hull. These can be repaired fairly easily.

I am sure there are others.

Jumper,

I'd go with Tigertiger's first suggestion.

The hatches are not sealed that well, and when it heels a LOT, as it does, you can't avoid splash events. I was thinking of using the old 'grease and rubber' technique to re-seal the hatches, but that'll have to wait till after I've taken the 'Black Yacht' on holiday first.

With a BIG bilge pump!  ok2

Hi Kit,

Going to go with TT - float tested the hull and we have a watertight compartment - always a blessing - so must be the goffers coming over the deck.

Will do some remedial on the hatch combings see if I can improve it.

See you in Lydney - where you sail the beggar?

Aye
