I haven’t had the chance to watch the video yet, but as an electronics engineer as training, if you want to blow your birdy brains try understanding the propagation of RF along a coax cable…then try how an aerial works…and for Einstein level, try RF down a waveguide as used on most radars. Nearly forty years on I’m still struggling with the concept that energy would rather travel down the air in the middle of a bit of waveguide than the solid bit of conductor that surrounds it!

Onan MDKAL Generator starts but shuts off #YouTube_Live_Stream

Kevin Cole
 

Our generator has been sleeping for a year and a half; we can start the generator but as soon as we release the start switch it does not stay running; we bypassed fuel shut off solenoid and generator will mechanically run; we have changed the oil, replaced exhaust temp switch, coolant temp switch, confirmed all K relays work except K4.  Wondering if we should flash the field and what method we should use.  Thank you, Kevin

Re: Seacock Replacement Ball Valve in Head

Rob Andrews
 

Hey Mark,
I did mine a few months ago and just used a 4 inch angle grinder (very carefully).  I could reach most of the way around with that and then finished off with a loose hacksaw blade.  They were the tools I had on hand and it worked without drama.

Seacock Replacement Ball Valve in Head

Mark Erdos
 

Hi Everyone,

 

Next week I being the joyous task of changing out the seacock in the aft head.

 

For those who have done this, do you have any advice on the best way to remove the fiberglass overlay allowing the valve to be turned? Also, what product did you successfully use for thread sealant on the new valve,

 

Thanks in advance!

 

 

With best regards,

 

Mark

Thanks Bill, This video blew my mind and actually raised more questions than it answered :D 

If I understand correctly Electrical energy is not like a fluid that flows through a pipe but carried by electromagnetic waves that radiates from the battery to the lightbulb in all directions.

But then, I believe, most of the power has to flow along the wires otherwise electromagnetic waves would cause all kinds of interferences in all directions radiating from all power sources.

So in that video, some energy flows in a straight line between the battery in the light bulb at the speed of light, but how much? Is it negligible? enough to turn on the light? If so, isn't this just an antenna effect? 

Thanks for sharing.

Adam,

If Amel doesn't have them fellow SM owner Paul Stascavage from Rita Kathryn had the same issue and had some replacements machined.  He had some extras made and as of July 2020 still had some available.  See this post:  https://amelyachtowners.groups.io/g/main/message/53463

You can ask him If he still has some for sale by replying privately in that thread.

Hi Adam,

If you search the forum you will find lots of posts about these things...
They are (were) available from Amel in La Rochelle - sav at amel dot fr
They can be quite difficult to remove as the stainless bolts and the alloy block weld themselves together over the years.
We took this fitting out and had an alloy plate welded to the boom...a la Amel 54, to avoid this issue in the future.

Good luck

Cracked Fitting on Main Boom

Adam Carpenter
 

Hello, 

I found the aluminium main sheet attachment on the boom is cracked on the aft end. 

Does anyone know where I can find a replacement?

Alternatively has anyone successfully repaired this fitting, it appears to be anodized aluminium.

Much appreciated.

We just tie it on the rail, will probably put a small cleat at the centre of the solar panels on the arc.

Re: Delivery cost from AMEL #spares

Justin Maguire
 

Shipping globally is simply WAAY more expensive due to the mess that is supply chain logistics right now.

Slavko,

I am in the USA and yes, shipping costs from Amel are pretty high.  However, Amel is probably charging you exactly what they are being charged by the shipper.  As stated earlier, Amel is a boatbuilder, not an online retailer.  Therefore, they have a very small shipping volume and are probably paying "full retail" price for shipping and are just passing this cost onto you (as they should!).  Large volume shippers get huge discounts from carriers like UPS, FedEx and DHL compared to low volume shippers. I know this because I own a small manufacturing business in the USA.  One of my customers is large distributor.  Because their shipping volume is thousands of times larger than ours they pay 65%-75% less to ship the exact same package to exact same place.  So UPS will charge me $100 to ship a package yet only charge them $25-$35.  Lately, the rates have gotten even worse for small volume shippers.

I keep a spreadsheet of "Amel Parts to Order" and then when the time comes that I really need them, I place a good size order.  I also tend to buy "generic" parts like oil seals and bearing locally.

Hello 
Since yesterday when I tried to park in a box in a marina in Auckland my bow thruster motor failed. 
If I turn the beam to the left or right the whole power supply breaks down for a moment. After that the power is back. 
I took the rudder off and it can be turned perfectly by hand. 
But the same happens with the engine. No power for a few seconds, all instruments off, no rotation of the motor. 
Does anyone know this problem. 
Does anyone know how I can find out if it's the motor or maybe a relay that doesn't work. 
Can I test the motor without a relay, maybe on the 4 cables marked D1, D2, and A1, A2?
I am grateful for a quick answer.

Re: Amel 55 - captain's seat

 

I am sure that Judy and I are not alone with what we did on passages. Most of the time we were not in the SM helm seat, rather we sat elsewhere in the cockpit. That said, we appreciated the design and engineering of the SM helm seat in heavy weather and especially a cyclone. That basic design is the foundation of the helm seat design for the SN, 54, 55, 64, 50, and 60. The 50 & 60 have the added features of an adjustable and swivel helm seat. The progression from the SM to the 50/60 helm seat is very clear to me. Each new Amel model improved the original helm seat from the previous models.

Some unique and especially beneficial designs and features in all Amel models are not immediately understandable. In fact, some of them took me years to completely understand.

This is the helm seat on an Amel 54. This photo says much about the Amel Helm Seat.

Joan, I'm sorry you're having trouble with the A55 helmsman seat.  I'm 5'10" and find the seat quite comfortable.  When sailing longer distances heeled, I often sit sideways in the seat with my feet up on the cockpit table and have a number of small sofa cushions in my back to increase comfort.
