Hi All,
Just a bit to add. We recently ordered our lettering from 'letteringonthecheap.com' for a very reasonable price. The front end is very easy to get around with lots of fonts and ability to add images. If in the U.S we had our stuff within a week.

Best Regards!

Re: Bow light wiring gotcha

Dean Gillies
 

Hi Kent,
I think the 54 is significantly different than the SM. We have a single Port/STBD LED unit in the centre of the pulpit. The wire needs to run inside the tubing horizontally to the stbd side of the pulpit, then turn aft through 90 degrees, then to the aft leg of the pulpit, then downwards and through a hole in the glass underneath the aft leg.
The 90deg bend is the real challenge !

Re: [Amel Yacht Owners] Re: Flexofold Prop

James Alton
 

Bill,

   A great post!  Your points about the problem of load matching a particular prop to various conditions is on point I think.  I was thinking about what you said about the fixed bollard test and prop walk possibly being almost useless data and am wondering if that is always correct?  I thinking this because generally when I shift into reverse, the boat will usually have little or no forward motion so there will be a period of time where there is almost no flow over the hull in either direction.  So in effect would this period of reversing when the boat is reversing direction not be quite similar to being tied to a bollard?   

   Can you tell me if there is a significant difference in the amount of prop walk (sideways) between a prop shaft that is angled such as on my Maramu versus the shaft on the SM which appears to be in line with the WL?  

   Again, interesting discourse, thanks!

Best,

James

But... it is a not a good measure of the real world performance of the prop in use (unless you are a tugboat).  For example, slight differences in pitch can result in fairly significant difference in engine RPM at full throttle.  If the engine is running at a different RPM it is producing different horsepower, resulting numbers would be skewed quit a bit in ways that have nothing to do with the design of the prop.  Our props typical ly run at about 30% slip, this test measures the thrust at 100% slip, a very different flow regime.

I especially think that measuring "side pull" at full throttle while tied to the dock  is a very poor stand-in for prop walk, to the point of being almost worthless.  Especially when you consider that props don't really produce side thrust on their own, it is the interaction of the slip stream with the hull that makes the boat go sideways.  A prop that had low "slip" (that's good) when the boat was moving would come out much poorer in ranking on this test than a prop with higher "slip" even though it would produce less prop walk when actually moving the boat.

It's easy to throw rocks at a published test like this and really, really hard to come up with a simple measure of prop performance. It is almost as bad as testing anchors! To be fair to YM they do acknowledge the li mitations of the testing at the end of the article.

My take-home story is that all feathering and folding props have so much lower drag than a fixed prop that whatever is left is totally insignificant on a cruising boat.  On our Amels there is no reason to discriminate between them based on this measurement.

Performance under power is really, really hard to measure in a way that you can actually compare apples to apples.  The interactions between engine, transmission, mounting geometry, gear ratios, etc, etc. will totally overwhelm the differences from one prop to another. Then there is the question of what performance measure is really important. Do you care about maximum speed?  Highest speed at cruising RPM?  Match of prop power curve to engine power output?  Maneuvering?  Motorsailing?  Fuel efficiency at cruising speed?  Overall fuel efficiency?  Different boat owners come up with different things of highest value to them.

 On one boat Prop A will be best, on another it will be Prop B. Without actual, concrete testing data on your exact hull with your exact drive train, the differences reported not really useful tools to discriminate between them.

Best to select based on whatever weighted combination of cost, robustness, maintenance needs, reputation, and advertising claims that feels right to you.  Certainly, do include published testing results in your evaluation, but understand if they used your boat in the testing the rankings might be very different in ways that would be unpredictable and, almost certainly, of very minor impact on the performance of your boat in the real world.

Re: Radar False Alarm :-/

Dean Gillies
 

Ok, no sooner typed and I found the problem.
For the record, yes it is a setting which needs reset.
Press Menu key, and select the Radar Menu.
The Radar Source field had some strange text in it, but when I dropped the box down there was another option of "DRS_Radome". When this is selected then the radar starts to work again.
Tricky!


Radar not detected problem

Dean Gillies
 

Hi all,

I have committed the cardinal sin of upgrading my Furuno MFD software when it was actually working ok before.

Ive always preached "if it ain't broke ...", however too late I didn't practice my preachings.


So yesterday I had revision 2.05 software on my MFD12 displays, and everything worked just fine.  I've since 'upgraded' to rev 2.07, and now my radar does not work. When I go to the radar display I just get a message on the screen saying "No Radar Detected".  


I'm guessing someone else may have done this upgrade and struck the same problem. Presumably it's some setting somewhere which needs adjusted - hopefully!


All wisdom gratefully accepted.

Cheers

Hi Dean.  I don't know how the 54 bow pulpit compares to the SM 2000, but on Kristy, I was able to use a steel tape starting at the exit by the starboard light and retrieving it at the bottom of the stanchion.  I attached a small line to the end of the tape and retrieved it at the stanchion without getting the steel tape out.  I then pulled a larger line through, then pulled the new cable through using some lubricant designed for pulling wires.  I felt really lucky after doing exactly what you did.

When I bought my 54 in August, the bowlight was not working.  Anyway, Lopo were great and sent me a new light free of charge.  Today I have been attempting to connect the new light, which has ended in a little disaster!


It was quite a challenge to remove the old cable which runs inside the pulpit rail with a 90degree corner at the front another maybe 70 deg corner at the aft end of the rail before going into the cockpit locker.


Eventually I succeeded in pulling the old cable through with a 3mm mouse line attached, leaving the mouse line to pull the new cable through. All good so far!


I then tried to pull the new cable through and only succeeded in breaking the mouse line before getting the new cable past the first 90 deg corner.  😡  The break was at the foot of the rail, where there must be a sharp edge which cut through the mouse cord. Maybe I should have a used a wire mouse line!


So, where does this leave me ?  Is there any clever way to recover from this and get the new cable through the pulpit rail?  


Time to open that bottle of wine Wolfgang. At least it's warm in here now :-)

Variprop

Hi Bill!  I also took a look at the report (2009).  I like your alalogy to the anchor testing!  BTW, they tested several props with "Vari" in the name but not the Variprop.  Also, they did not test a 4 bladed prop.   Anyway, I will write SPW GmbH and ask them what the current price is for the "Blue Water".  I know they have our SM on file.  I will also ask them if they have provided props for other Amels.

Re: [Amel Yacht Owners] Re: Flexofold Prop

I replaced my auto prop with a max prop when I repowered. The auto problem is a great prop, but requires regular maintenance to keep it functioning properly.  The Maxprop has been flawless for 4 years with only one removal/greasing when I hauled out for bottom paint and new prop shaft seals.

Hi I have an Amel 54 with Brunton Autoprop. I am happy with it and have experience of Maxprops, and Featherstream as well as fixed props. I also read the prop comparison article. My view is that the test showed the Autoprop would achieve 6 knots at 2100 rpm verses 2500 for the others. Looking at my own boat fuel consumption stats, it shoots up steeply with rpm. The difference between 2100 and 2500 is massive. Also it is better for the engine to be more highly loaded at lower rpm’s. Furthermore lower rpm is less noise and wear.

Dean, The only reason that I am considering to go with Flexofold is the test results conducted by Yachting Monthly . You can find a link on Flexofold website . Overall they surpassed every other prop in the majority of areas tested. Only in backward thrust did they end up in the middle of the pack. Forward thrust which is far more important , they were top rated. The drag is so low it could not be measured , but that would be true for all folding props and nearly true of all feathering props as well. I am going to see if I can find any other independent  comparisons of props , but check it out and draw your own conclusion .

Interesting thread. 

I'm also changing out my fixed prop, but was leaning towards the Autoprop which was specified by Amel on other 54's.  Was there any compelling reason you chose flexofold over the Autoprop Patrick?

The Autoprop is priced around 2700GBP+VAT. Not sure how that compares to the flexofold?

Congratulations Mark on your new Amel.  I can't tell you the depth of the locker as I am not on the boat, but it is close to 4 feet.  I just bought a 6-man Switlik that weighs about 60 lbs and is a considerably smaller package than my old Datrex raft.  I'm 70 years old now and don't think I'd have any problem yanking it out with adrenaline pumping.  It is very close to the extra mizzen halyard if necessary.
