Hi Alan,

 

Thanks for your reply. I will ask Olivier Beaute. He surveyed my boat 2 years ago and noticed the worn out earth plates in his report.

 

Kind regards,

 

Willem

Hi Willem,

Our plates seem to be attached with rather large slot headed screws/ bolts.
I would doubt that they are just self tapping, I'm sure they would thread into something inside the rudder.
Our plates....and we're not that much removed from you # wise ....are just fine...I work them over with a wire brush on a drill every time we haul out...they haven't actually decayed at all...and the SSB performance is always improved after the wire brushing.
BUT the ONLY person who would know for sure how they are attached is OLIVIER BEAUTE....
OLIVIER, perhaps you can answer this question ?

Hi Alan. I had a new interphase transducer fitted on the center line. I couldnt give you the measurement but I noticed it is much more than hull normal thickness. It seemed the v had a reinforced impact protection thickness. Sorry cant be more help.

I'm going to replace it with a Navico forward scan transducer and a B&G Vulcan FS display.

The probe transducer is on the centre line forward of the depth sounder.

I know that the Navico transducer housing is a larger diameter than the probe threaded stem, but what concerns me a bit is the thickness of the hull there. 


Does anyone know how thick the hull is at that point on a Super Maramu ?

Hi Duane,

Id borrow the limit switch from Joy again. See what happens. If not available try another new switch. Check all wiring connections, a bit of corrosion can cause funny things to happen. I get good results with WD40. (OK Alan it works) Corrosion X is recommended too

I received the new limit switch today and still no joy.  


This is confusing since, in diagnosing the problem (bow thruster would not retract), I borrowed a new limit switch from another Amel SM  (JOY), put it in the lowest position on the Actuator (marked "H") and the Actuator was then able to raise the bow thruster to retract it into the hull.  From this I assumed the problem was the limit switch.

Okay, so I get the new switch and install it in the "H" position (lowest on the actuator tube).  With the new switch in place I tried to lower the bow thruster motor.  The lights on the "SP" and "B" switches lit up, but the actuator motor did not engage.

I switched the toggle switch at the helm to the "UP" position and the lights on the "SP" and "H" switches lit up, and the up buzzer sounded.  This seems right since the thruster motor was "UP". 

I replaced the "B" switch (the upper position on the actuator tube) with a new one, and repeated the procedure above with the same results.

I'm starting to wonder if the actuator motor is burnt out, so tested the motor wires for continuity through the motor and got continuity.

-What else could I test?

-If the actuator motor was not working it would explain the current situation, how do I test the actuator motor?  And, if it's shot, why did it work to raise the thruster motor with the borrowed switch?

-What does it mean when the light on the limit switch comes on?  I find it odd that the "SP" limit switch light comes on when the thruster motor is all the way up.  I tried to activate the thruster prop in this position and it did not activate.  From that I assume when the limit switch light is on, the motor is locked out.  The old switches were marked with a "Normally Closed" icon.

-Which switch controls the limit of the bow thruster motor up and down?  Is the "B" (on the top of the actuator tube) the limit switch for the down position for the thruster motor?  And the "H" switch (on the bottom of the actuator) the switch for the "UP" position of the thruster motor?)

-I don't understand why with the bow thruster motor up (and you get no movement of the thruster motor):
When you toggle the actuator for "UP" the switches look like this:
SP (lit)     B (not lit)

H (lit)

When you toggle for "Down" with the thruster motor up you get this:
SP (lit)B (lit)

H(not lit)

Any ideas out there?
Thanks,

Bow Thruster Wiring and French terms??

Duane Siegfri
 

Looking at the Bow Thruster wiring diagram in the Files section, there are four control wires going to the Thruster Linear Actuator.  Two are marked "lev" and two are marked "tem".  I am guessing "lev" stands for "lever" or "raise" in english. 


What does "tem" stand for?


Note that this is a 1987 drawing, so likely not representative of the current design.  Does anyone have a more up to date wiring diagram of the bow thruster, especially the linear actuator?


Thanks,

Duane

Re: Support for Liferaft on rails

greatketch@...
 

As far as I know, every liferaft manufacturer makes a rail mount holder to fit the life rafts that they have packaged for exterior exposure.  Have you contacted them? Design of these isn’t always simple, especially if you use a hydrostatic release.

Our thinking on life rafts has slowly evolved as we have lived with one, and reading about those few cases where people actually needed to deploy one.  

On an Amel, with multiple watertight compartments, it seems the most likely reason for needing to take to the raft is an uncontrolled fire on board. With this in mind,  I do not consider storage below deck a good idea.

I have no issue with storage in the bottom of the Amel deep Port side deck locker.  Anything stored on top would just be thrown overboard in an emergency.  Yes, our four-man raft is heavy (80lbs/40kg) but not so heavy any single crew member could not lift it if they HAD to.  A 6 or 8 man raft changes that calculation a lot.  A 8 man raft is really heavy and awkward.  If I felt the need for 8 man raft capacity I would seriously consider using two four man rafts!

We have ended up with our valise packed raft in the cockpit locker as part of our ongoing effort to move weight as far starboard as possible.  I am liking it there for another reason, it gets looked at a lot!  It anything was going wrong, we would see it.


Re: [Amel Yacht Owners] Forward Sonar

Alan, The threaded stem is pretty long on transducers , I don't think you will have a problem . I would guess the hull is probably 11/4" thick , just guessing . I had a B&G sonar transducer installed last year and there is plenty of threaded stem inside . It went in the hole where the Interphase twinscope transducer was located.

Thank you for the feedback it seems that we are in line with the storage on the stern railing.  The big question is now where do I get a stainless steel holder that is suitable.

Re: Bow Thruster won't come up

greatketch@...
 

Duane,

When a DC electric motor starts to work intermittently, and power supply is not the problem, the next place to look are the brushes.  

I would think that a brush problem is unlikely with the thruster jack screw motor because it accumulates so few hours of actual operation, even on a heavily used boat... but stranger things have happened!

I keep my 4 people liferaft in the aft cabin under a desk. It is better protected inside.
Better not to rush with liferaft deployment. You have to "stap up" on the liferaft when it is absolutely no doughs that a boat is going down. It is always better to be on a partially submerged boat than on the liferuft.

You can always bring a liferuft to the cockpit when things are going very bad.

Re: [Amel Yacht Owners] Support for Liferaft on rails

Hello,
Our life raft is mounted on the port stern rail. It was like that when we bought the boat and I find it a pretty nice solution. There is one long stainless steel pin to release it. I’d hate to have to dig down into that locker for a life raft in even calm seas. We’ve got diesel jerry cans and fenders in the locker instead.

If you wish I can take a photo and post it to the group. I’d be surprised if there isn’t one from someone already though. We’ve seen many Super Maramu with the same setup. This topic has also come up before with much discussion about safety and sunshine hurting the life raft.

Cheers,
James.

Question about earth plates replacement

Willem Kroes
 

Hi fellow Amelians,


The earth plates on my SM 2K need to be replaced (the bronze 'bubbles' are gone for more than 60%). The plates are connected to the antenna tuner of the ssb transceiver.

My question: how is the installation of the plates done. Can I expect a laminated bronze plate inside with screw threads tapped?
Or is there only a cable connection and the attachment of the plates must be done with self tapping screws?

I am not on my boat now and I want to know how to instruct the mechanic of the boat yard.

Fair winds to you all,

Hi Ann-Sofie. I am repeating myself here. The super wind has no noise and no vibration, and in nine years I have not once had any adjustments to make or service needed. Probably why they are twice the price of alternatives.

We hade similar plans, to install the wind gen on top of the mizzen. But now we are glad we glad didn't. The blades needs to be adjusted very often, and it is not that fun to climb the mast. Also, the resonance through the mast can be very enoying, unless you find a solution for it.

We plan to install a wind generator probably a Rutland 1200 on top of the mizzen mast.

 

We are currently not at the boat (Georgetown Maryland) and wonder if someone know how the top of the mizzenmast look like? Measures? Is it easy access to put nuts and bolts through the top to bolt the wind generator? Any advise from someone who have made that before would be appreciated. There is a mounting kit in aluminium available for 499 $ looks expensive to me, thinking of having one made in 316 SS would probably be less cost. Weight a loft is of course an issue.

Thanks very much for your reply. You seem pretty certain about that. I did already replace the failed wheel for the 240v motor less than a year ago and so far its been fine. I cannot understand though how the 24v motor runs fine under no load and only stops when the pressure is turned up if this is due to a failing bearing. Surely the bearing either works or doesn't?

A guy here in Martinique suggested I check the motor brushes - a lot cheaper than buying a new pulley wheel!
