[Amel Yacht Owners] Head sail furling


Bill & Judy Rouse <yahoogroups@...>
 

I am guessing that it could be a lot of things, but, I will give you some guesses to eliminate because I have not experienced this. I imagine you have already eliminated these, but since you did not say, here you are:
  1. That motor is very strong. Is it possible that the swivel is binding? Maybe the external halyard is jamming something at the top, or some other cause of binding.
  2. Is there an alignment or tension issue? I believe that not enough tension on the Genoa Halyard will cause the foil to whip around as furling and unfurling happens.
I wish you well as you explore the reason.

Hey everyone-


I have not look into this yet but last year I had the issue where the furling motor sheared from the plate that spins the sail out (while locking pin is engaged). Well, yesterday I had the same thing happen less than 1 year after it was "fixed". I actually furled into the wind under light air conditions. You know, no problem just used the cross method and rolled the sail manually but I am confused and frustrated as to why this is an issue. Can anyone chime in with suggestions or comments? 


Many thanks,

Could it be the rivet?

Here is how mine look before i change them:

Bill,

One more guess...

Maybe the worm gear inside the furler mechanism is somehow binding. I would guess that if this happened the motor would shear. Possibly a bearing or bushing has caused the gears to get out of alignment and they occasionally bind.

I think after you check the obvious, this is next on your list.

Okay, so I looked at it further and it looks like it is working. It is wobbly as all hell but the bolts have not sheared off. The furling motor is fine. The rivets do look a little loose but I am at a loss as to why it would just completely unfurl while the pin was engaged yesterday and now it works "okay". Some work definitely needs to be done but I am not sure. The head sail is tight but the foil wobbles when rolling in under power. Thoughts?

Hi Bill.
If you can furl manually with a line, the rivets are intact.  If the pin is engaged, but the motor doesn't turn the foil, you must have a failure in the gear box.  If it is "wobbly", that confirms that a gear or bearing is out of place.  What did you ("they") do to repair it last year?

“Foil wobbles while rolling in…” Is the tension on your headstay high enough?  Furling while the headstay has a larger than normal sag to leeward will heavily load up the mechanism and could be contributing to issues.

Gearbox needs disassembly, inspection and probable overhaul.

And Genoa halyard may not be tight enough and/or forestay may not be tight enough.

That this makes perfect sense. I am going to disable the gearbox and rebuild. Rivets absolutely need replacement but I can confirm this is not the issue because as Kent pointed out I was easily able to furl the sail with line. Cheers to all my fellow Amel owners! As always this group has proved to be an outstanding resource.

Kent,

Sorry to hear about the detached retina.  Let you friends here know if there is something we can do to help.  Brava is on the hard for hurricane season, so I am at loose ends in Massachusetts, and am available to assist you if needed.

Bill based on your discretion the worm gear bearing/ bushing is worn allowing it to run free. Normally it's a self locking system.
