bow thruster maintenance

curtepp
 

I have downloaded and read the various PDF files re. thruster maint. and seal replacement.

Thanks very much to those that have posted those files.

Our Maramu is in Fajardo, PR and I intend to do the maint. in Nov. before we launch.

Q:  Where do I buy the parts for the maintenance and for spares aboard?

Thank you for your help.

It has a pin that goes through the middle like a shear pin. The nylon bolts hold it all together. The nylon bolts are the shearing parts, not the metal pin. It us simple and it works (recent unfortunate experience with a stray rope). I put a new prop on wearing a mask from in the water. It wasn't difficult.

That's what I thought, too.  The CDrive is definitely an proprietary Amel part.
Did you find someone to work on your electrical/electronic problems?

I never spotted any manufacturer's identification on mine, unlike the boom and mast reduction gears that were clearly marked "Bonfiglioli".  There was a motor manufacturer's nameplate, but that's not what you're after.  I had surmised that the jib furler gear assembly was custom manufactured just for Amel, rather than being an "off-the-shelf" item like the mast & boom ones.  Isn't that the case with the "C" drive gear housing that you're replacing or was there an outside manufacturer?  It does make you wonder that Maud doesn't seem to know.

Re: [Amel Yacht Owners] Light Air Sails / Bow Sprits and attachment points

Alexandre Uster von Baar
 

Hello Terry,

Mine (SM2K #289 now NIKIMAT) came with a removable bow spirit installed by the (long term) previous owner.
As I mentioned previously for the staysail, he is in my opinion a very knowledgeable sailor, own several Amel including Mango, Santorin, SM2K and currently Amel 54.

During our various discussions as much as he admitted the "staysail" never really met his expectations...
He clearly said adding the Spinnaker was a great addition, easy to install and also providing more point of sail than the ballooner.
The spinnaker sail is stored in the same locker as the ballooner (I put it below it), also in a bag.

I personally never used the spinnaker. But I just took some pictures of the (partial) set-up.
As you will see, I added the 2 dyneema shackle to go around the big forward cleat.
I believe this is a good solution, if that cleat can hold the anchor, then it can surely be attached to the bow spirit.
I purchase dyneema lines, which when I use the removable bow spirit will tie around it and the forward cleat to avoid lateral move of the bow spirit.

At the top of the mast, there is a ? (forgot the name in English) like a block to raise the halyard of the spinnaker. Unlike the one for the ballooner, it is outside the mast.
Just like the Mizzen Ballooner, the spinnaker is in a sock (from http://www.atninc.com).
Also there is a block at the tack that allow to raise and lower the tack.
Some of the internet being down in Nassau, I couldn't browse for the video on their site, but there is/was one.

Note from the (long term) previous owner: using the removable bow spirit only give a couple of degree more.
He really suggested, for the first time to use it without it and attach (somewhere on the bow) (I will have to look for the notes).

Note: Last year, trying the ballooner for the first time, I made the unfortunate mistake to twist both halyard (spinnaker and ballooner).
This was a stressful experience resulting in the ballooner falling into the water, then the halyard for the genoa breaking down...
So should you go with this rigging, make sure the spinnaker and the ballooner halyards are free from each other.

Anyway, pictures of the set-up

Good day, I would like to get an idea
of how many Amel owners have retrofitted their boats with
light Air sails and of more interest how often are they
used. I am specifically referring to Spinnakers, Code
Zero's, Gennakers etc. My wife and
I are preparing for an extended cruise across the Pacific
and hopefully beyond. We have the factory standard Headsail
Balooner and Mizzen Balooner. Anything upwind of the
Balloners useful work angle seems to be a gaping hole with
respect to light air.The other area of
interest is how the sail tack is attached to the boat. I
have no faith that the bow roller has the strength to serve
this purpose. Considering adding a separate bow sprit
attached to the deck or hull.
Anything that can be shared would be
appreciated.

Re: [Amel Yacht Owners] Bow Thruster Prop ... yes, I'm new here.

Gary Wells
 

OK .. Got it! Thanks. It was just stuck hard. Two properly placed pry bars and a tap on the shaft with a plastic hammer did the trick. I'm just shy yet, I guess.


Re: [Amel Yacht Owners] Bow Thruster Prop ... yes, I'm new here.

Yes Gary, there's a pin that hola the hub on the shaft.  The nylon bolts hold the prop on the hub.  Once the bolts are out you can pull the prop off...be careful the pin doesn't drop out and get lost in the deep.  One of my hubs fits very tightly in the prop and requires some work to get the prop off. The other hub isn't so tight and it's easier to remove the prop.

Re: Genoa Furler Identification

I'm still hoping someone can help me identify the manufacturer and model of my genoa furler.  I don't understand why Maud/Emilie are having a problem with my order of parts, but they say they need more information on the furler.  It's the one depicted in the Files section called "genoa furler Diagram.pdf" in the folder "Super Maramu Jib Furler Technical Info".  There is a pic of this furler in the Photos section in the album Ipanema.

Thanks in advance,

Re: [Amel Yacht Owners] Fore and aft loading a SM

Anne and John Hollamby <annejohnholl@...>
 

I suspect that the built in waterline being topsy turvey may be because the line was originally correct when Amel was making a shorter model perhaps the Maramu. Then they lengthened the mould each time and added more weight with the extensions to the aft end but they did not reset the moulded in waterline on the unchanged front section. Either way it is very important to ignore the incorrect line or have it redone from bow to stern. Weighing down the bow is a recipe for disaster. The other critical point is to make sure that the up wire on the thruster is bar taut when the unit is pinned up and that it is raised as soon as the boat has steerage way. Our unit has never let any water in since we  got it in 2001.

Hi Alexandre,
You make a good point. However when we are sailing with the bow regularly plunging into the sea the bow thruster is not only well below the water there is considerable pressure applied to the seals by that plunging especially when going to windward in a significant sea when the water will often be to top the top of the bow. So we need good attention to both the lip seal and the foam seals.

Good morning,



Sorry forgot the link:
http://www.nikimat.com/bow_thruster_repair_issue.html



A word of caution loading too much, or too much on the bow
your vessel.

Last year, when I slowly moved in I tried to balance the
water line loading more toward the bow.

I also like better how she sailed (more weather helm).



BUT, when I serviced the Bow Thruster in the water, I noted
the water was dangerous closed to the top of the cavity
where the bow thruster retract.

As you can see on the 5th picture. (Disregards the comments
on the page, these are old)

An inch more and water would have come into the vessel.

So after that I got ride of a lost of thing and rebalanced
evrything and now have over 3 inches space.

And you know it because the frequency of the need

to get in the water and scrub around the waterline
increases

!

AND every SM that I

see is like ours...high in the bow and low in the

stern...too much weight aft...but why are they all like
that

?...i think its because Amel never changed the waterline

even though in the Maramu development they added a lot
more

weight aft of the centre of buoyancy

EG the drawings shown the rudder

stern gland above the waterline, but when we replaced
our

packing recently it wasn't, the water was flooding

in....it doesn't now thank goodness !

Re: [Amel Yacht Owners] Super Maramu Staysail

Anne and John Hollamby <annejohnholl@...>
 

Hello Bent, My post of 29/09/14 gives an answer as follows:-
,
In case it helps, on my previous boat, an Oyster 435 I had an inner forestay fitted but it was fixed less than three feet from the top of the mast to avoid the need for running backstays. This was on the advice of Oyster and they called a slutter rig. I too would be interested to see how and where to fit the track  on the deck of an SM2K. The only problem with it was that the new fixings for the inner forestay or sheave box projected into the mast and chafed through a headstay halyard. However the rigger returned and fixed that problem. The purchaser of that boat sailed around the world on it without problems with it.

propeller shaft lubrication OLD Maramu 1989 #261

There are 3 hoses attached to the propeller shaft, one hose has a greese container with a T handle to turn and force the grease into (or around) the shaft. What kind and grade of grease should be refilled. Also the other 2 hoses are connected to an oil reservoir through a copper coil. What type and grade oil is this and should it be replaced? Thanks in advance, Ross Maramu. 1989 #261

I have a very mundane question; we need a new MW/Grill/Convection unit.  TWTMBO (... must be obeyed) wants a more multi tasking unit.

Anyone have suggestions?  Limited by the cabinet size on an SM.

Cheers,

Colin, I think Alan was telling you that Yahoo truncates email addresses from your email and he does not know what comes after the @ symbol.  You will have to spell it out for him using  "at" instead of "@".

What about backstays? I would expect that this was required, at least in heavy weather?
