Nangee
« on: August 27, 2007, 05:22:45 PM »

Jus started on my MMM Nangee.
I'm fitting two ASDs
Only problem (so far) is that there is not enough headroom under the stern deck, I did realise this before I purchased the hull.
I have two options, as I see it:
One is to fit the deck at the original level but with raised cut-outs to accomodate the higher parts of the drives.
The other idea, my prefered, is to fit the whole deck flush with the top of the hull. This would then be at the same level of the forward deck. The stern deck would be in the style of Afon Cefi

Any thoughts anyone?

Could you disguise the 'lumps' as deck cargo?

I've gone with the deck flush with the top of the hull, effectively the same level as the forward deck.
Had its first outing today performed well. don't think I'll need the mixer, not even sure if separate contols are needed for each motor.

A bit too rough for a proper trial today, must fix the battery it shifted a bit and gave a list to starboard.
The crew member was pleased he had a elastic band to hold him on,

Hi Frankie, looking good.
What do you think of the Shottel drives? Are they noisy? What motors are you using?
I am thinking of using the Shottel 11's in a tug & would welcome your observations.

They are somewhat noisey, not too noticable when on the water. They sound a bit nasty out of the water, but the instructions tell you not to run them on land too much.
I'm using Model Motors Direct 777s.  they are only just under the deck so "fatter"ones would have been a problem.
I had thought of lowering them and using a belt drive. There is a built in 3:1 reduction in the Schottels to bear in mind when picking motors.
I think the ones I have will be powerful enough, running on 6 volts.
I've put a bow thruster in but don't think it will be needed much !!

Hi Frankie

The noise will lessen once the drives are run in.

I would recommend independent control of each drive, there would be no need for a bow thruster, as you would be able to, with practice make the boat move sideways.

I have used twin azithmuthing thrusters on my French Harbour tug and my new build is a Rotor Tug with 3 independent azithmuthing thrusters driven by MFA 800 motors.

I prefer this method of propulsion over fixed props with Kort nozzles, you have far more maneuverability, great for steering comps.

Great build.

Completely independant?, ie 2 channels for steering and 2 for the ESCs?
I could put the left drive on the left stick steering and speed and right on right stick similarly...is that the idea?
does that present problems going straight?

Hiya Funtime, yes that is what a properly set up ASD tug is like. I used a Futaba Skysports 4 $0 Mhz FM set with exactly that set for steering & throttle on each stick . Worked a treat for me. Admittedly there was a large skeg which gave increased directinal steadiness. I miss that boat a bit now although it was  a lot underpowered with decaperms on direct drive through planetary reduction gearing on 6v. It'll be interesting to hear how your Nangee performs once run in a bit.

cheers

Got it set up with a channel for each function now. Goes straight well enough. Turns only need one drive turning, if both are used it does "handbrake" turns.
Not mastered going astern straight yet.

          ...Hi Funtimefrankie...

Smashing Looking tug...

If you chamfer the front of the deckhouse it makes it an entirely different tug...Almost like a smaller PORTGARTH...

UM....I'm not keen on the front, toooo square..... I think sometime in the future I'll make a another deck house.

I'm pleased with the wiring, it goes up through two tubes, the wheel house roof is three layers, the centre one having tracks for the wires to spread out to the nav lights and up to the mast. So no wires on view. O0
Switches in the hose reel locker. and an old sevro for the radar
Pity I didn't put enough in to start with,  :( ie another two for the search light and stern facing nav light, and perhaps a light in the wheel house.

                    ...Hi Funtimefrankie...

Here is a picture of my NANGEE based tug....I called it ALBA...This picture was taken just before it was stolen in a Break-In at the clubhouse....

I originally built the deckhouse the same as yours (as per the plan) But later cut away the squareness at the front and changed the tugs appearance completely...

I have since built several other tugs using the NANGEE hull....I consider it to be a very versatile wee hull....

 ...Best Regards...Norry...
