I more or less understand the practicality of having that much control via the props and thruster. I merely don't know how effective the single rudder will be with the twin props. It seems like they would have done something like the Elan 450.

Any updates / images of her under sail, or complete with her rigging up?

Truly a spectacular boat.

Yes, here she is: http://www.yachtforums.com/forums/ro...ns-athena.html

And SigSplash, I doubt Athena will need two rudders, they are for fast boats that can have a broach when the rudder is lifted out of the water. Under engine she wouldn´t need a rudder at all... but it is good for the autopilot.

A twin screw yacht would have two small rudders behind each prop for proper steerage but the Athena is so big she needs that much rudder under sail. When using the props there would be no problem steering her as the water would be thrust along each side of the rudder giving her plenty of steerage even at very slow speeds. However as stated above with twin screws she wouldn't even need a rudder as the steering can be acomplished by vectoring the speed of each prop or backing one while the other goes forward for a sharper turn. The variable pitch props could help with this too although that's probably more for efficiency and speed than steering. Pete

Good explanation, thanks.

Norgale · 07-09-2008, 12:51 PM

Hey SigSplash you are most welcome. Would you have any info on the call sign for the Athena? Pete

SigSplash · 07-09-2008, 01:41 PM

I'm not sure about her call sign, but this may help: http://www.cdlive.lr.org/vesselstatus.asp?LRNO=1007237

Thanks for the link SigSplash. It does show the registration number but what I'm looking for is her radio call sign. Usually three or four letters and then a number.
You can go to "ship locator" and see the position of all ships that are out on the sea but you can't id a particular ship unless you have the radio call sign. With that you can tell exactly where the ship is at any given time.
My interest here is that I'm building a model of her to go R/C sailing. If she ever got close to where I live I'd go and take a look at her and get some of my own pictures. Pete

I found a database that said her call sign was ZCNP.

Here is the link: http://e-ships.net/index/A16.shtml

WOW... just wow.
Jaw dropping wow.
What an amazing boat.

Norgale · 07-09-2008, 02:47 PM

SigSplash that's it. I've looked everywhere for the listing but just didn't hit on the right list. The last group I found has 50 Athena's listed and didn't find the right one. Thanks very much for this link. Pete

SigSplash · 07-09-2008, 02:55 PM

No problem.

I've just seen the photos of Athena being moved from the build-shed.

Those motorised platforms she is on are from a Dutch company called Mamoot (Mammoth). Fantastic machines, they have V8 Deutz engines linked to hydraulic motors and axles that can be linked in multiples of how ever many you need. They are driven by one person with a walk-about remote control.

A Dutch guy I met in Venezuela was moving an oil refinery with a set of them and showed me around all the kit. They even have a super-crane that packs up into 12 shipping containers.

Interesting bits of kit.

Those are very effective and efficient. We use them constantly.

What a gorgious vessel. Just playing with an image in my mind, removing the mainmast (center), replacing with a couple of staysails between the fore and mizzen, and installing one or two tall funnels to the boilers feeding the two triple expansion engines, what can I say lol. The images of her without her masts reminded me so much of the classic steam yachts of the past.
