Re: Loosing oil from Furler Genua

Craig Briggs
 

Hello Casper and Vito,

I just refurbished my furling gearbox and I'd be quite sure that the grease you're seeing from the bottom of the furling drum is because the seals are failing in the gearbox - most likely it is not from the grease on the headstay inside the furling extrusion.

I'd further assert that adding grease (any quality water proof gear or axel grease will do) through the Zerk fitting (mine doesn't have one) won't really solve the problem of worn seals. It may keep water incursion at bay temporarily, but the grease shouldn't leak out.

My furling gearbox had just started to leak last season and when I disassembled it there were telltale signs of water getting into the gearbox where the seals had failed. That included damage to the bearings, which had started to be noisy. I was easily able to obtain replacements for everything and the gearbox is like new - no more drips!

As for the headstay grease - I simply donned rubber gloves and slathered on copius quantities of waterproof axel grease (about a liter in all) as we fed the new headstay cable through the furling extrusion - kinda fun! Unlike the furling gearbox, which I'll certainly be opening up more often, I would not think one needs to regrease the headstay periodically - just when you replace your rigging.

Good luck with it all - and, by the way, I'd strongly suggest you do the same maintenance for the gearboxes on the main furler and outhaul - especially if they are getting noisy - a certain sign of bearing failure or worse.

Hello Casper

Yes it is normal to loose greas from the bottom of your furling drum. Amel fills the entire foil with grease to help the foil to turn. I am sure at some point this needs to be replaced. Has anyone done this.

Dear all,

I am loosing oil (greece) from the bottom of the electric furler of the Genua.

Is this a normal thing?

I see there is a nipple on top where I could refill. Does someone know if that is the solution and if so what should I put in there?

Re: Replacing Standing Rigging

Craig Briggs
 

Hi Kent,

Glad the info is helpful - good luck with the project.

Here's a couple of afterthoughts: most important is to absolutely take this opportunity to open your jib furler gear box and thoroughly maintain it - replace all the seals plus bearings, especially if there's any sign of water ingress.

Caspar and Vito were recently talking here (on the DB) about grease leaking on the deck from the furler gearbox (it's probably not the grease inside the furler extrusion) - that's not normal and imho is the clarion call that you're overdue to open up the unit and fix it. Btw, these are all stock parts from mechanical suppliers so no need to go to the factory. Same thing for the outhaul and main furling gear boxes - may as well stick new brushes in the motors too, and burnish the commutators.

Second, and another good suggestion from Joel, is if you going to take the masts down for the re-rigging, that's a good time to repaint them if they need it, plus refresh wiring and light fixtures and replace the UV damaged nylon washers all over.

And, no, we ended up not keeping anything for spares - we did cut open one of the swages and confirmed that they had a scary amount of corrosion in them, plus the inner strands of the cables were really rusty. Made us feel better about the need for the job, if nothing else. If I were inclined to carry spare rigging, it'd be interesting to look into Hi-tech rope, like the maxi's use, though terminations are tough, I understand.

Cheers, Craig

Re: [Amel] Re: Mounting of AIS GPS ANTENNA

kimberlite <kimberlite@...>
 

Ok here is the explanation.

The AIS B is required to have its own GPS since the boat it is mounted on
might not have a GPS.



The GPS dome does NOT transmit it locates my boat and sends it out vis the
VHF antenna that I had originally installed for my AIS receive only unit.



The AIS (by nasa) receive only used my ships gps to locate where I was in
reference to the transmitted location of other ships.



I hopes that explains the AIS issue.

Re: Genset Cooling Circuit Airlock

Ian,

It is possible that you may have a small "air Leak" in the stainless steel pipe that runs from the left side, back side of the genset, under the engine to the hose that connects to the salt water pump on the genset.

This pipe had a small manufacturing defect in it on SM 387. It casued air to enter when running and leaked a small amount of water when the genset was off. If you have any signs of salt accumulation in the pan under the engine, this might be your culprit.

This happend to us and one other SM that I am aware of.

Examination of the raw water strainer shows that after sailing the water level is below the T-off for the genset cooling water.

Not sure why you'd have to have a dedicated GPS for the AIS. I don't see
why you can't use your VHF antenna as well, unless the AIS transponder
interferes with radio transmission...haven't looked into it, but seems like
you could have the AIS transponder disabled whenever you are keying the mic.

Hi Kent,
We just finished replacing ours - here's my 2 cents:

You didn't say if you'd had a problem or not, or if you just judge your rigging to be too old and want the added comfort of new rigging (or maybe your insurer wants it)(what year is Kristy?). Would be interested in your thinking.

Ours was 18 years old with a few years in the tropics and we had a mizzen lower break on us last year at the lower swage - that's a clarion call in my book!

Per great advice from Joel - replace everything including turnbuckles and clevis pins. I'd include new bolts for the toggles at the spreaders and mast top, too.

We found a great price and super support from Seco South (and had great experience on previous boat with them)- unfortunately, the shipping and customs into Italy about doubled the cost. Thus we went with ACMO - the original French supplier to Amel. They didn't charge us VAT, as they billed our US address, and shipping was only 190E. The advantage, of course, was that they had the exact specifications.

By the way, ACMO apparently used to engrave the exact measurement of the shrouds on the lower swage. If yours is the right vintage you'll see numbers like 19285 (or whatever) which is the millimeters of length from pin-to-pin with the turnbuckle in the 1/2 closed position.
On our new rigging from them they've changed that and now engrave the date of manufacture. If you contact ACMO, they may be willing to email the original specs, which you can cross check with the engraved numebers on the boat.

As for mechanicals over swaged, I'd have preferred mechanicals, at least on the bottom, but the price was about 20% more, so we went with swaged and that did save me a lot of time when I installed the rigging.

That took about a week with Katherine hoisting me up and down the masts as we replaced the shrouds one-by-one. I much prefer "hugging" my rigging myself and knowing it's done right (I recall finding your "professional rigger" in Texas having left out the headstay cotter pins)- but hiring it done is easier - remember you get what you inspect, not what you expect!

Had we gone with Seco South, we'd have changed to US sizes, and right hand threads, instead of the left-hand threads that Amel put on the boat for some reason (if anyone knows why, I'd be curious.) Btw, we saved a bundle by going right handed, even through ACMO.

One peculiarity you may have to address is that the head stay turnbuckle may be a specialty item that's shorter than normal - we only had 14" from the bottom of the furler (the wrench flat on the swaged bolt) to the pin and the American suppliers didn't quite know how to address it - Acmo had the original size turnbuckle. (This may be a peculiarity of the Santorin, not your SM, but do check - also, you may not be able to use a mechanical fitting there.)

We debated on keeping some of the old rigging for emergency repairs but decided against it - too many "treasures of the bilge" on board already, but belts and suspenders aren't all bad.

Good luck with the project,

I'm going to have my standing rigging replaced this summer and have read all the previous posts I could find regarding same. What are your thoughts about swaged vs mechanical fittings? Would you replace all the hardware, too? I'm thinking I'll go with the swaged fittings and keep the best old one of each size as spares. Maybe buy an extra-long mechanical fitting of each size to do repairs as I'm told that breaks usually occur at the lower-end fittings. Could maybe do a repair even at sea??? Would you change to US sizes instead of metric?...I'll be sailing in S. Pacific before these start to wear out, so I'd like to have some ability to do repairs if something snapped.

Any thoughts?

Eric,

You will loose a lot of distance with VHF by mounting it low.

Our AIS receiver which currently shares the AM/FM antenna on the main mast.
The AM/FM antenna on SM #387 is identical to the VHF antenna. I used a BNC
"T" to split the antenna wire for the radio and the AIS receiver. I have
noticed no problems with either the radio or the AIS receiver. This will not

work for a AIS transponder, but, I am considering buying a small antenna for

the radio, placing it inside the radio drawer. This will leave the AM/FM
antenna exclusively for the AIS transponder.

On SM #387, the triadic stay is rigged with insulators and the coax cable
from the stay terminates in a coil behind the radio/Hydra drawer. I think it

is too long for proper VHF (300mhtz = 1.6 feet of antenna for one-half of
the signal's total wavelength), but possibly could be used to receive AM/FM,

freeing up the Main Mast AM/FM antenna for your transponder.

Let me know what you do.

Best,

Bill

Sorry, I misunderstood what you were looking for.

We have 2 GPS antennas mounted on the Port rail. They are 6" apart.

Each antenna goes to a separate Furuno GPS receiver. The 2nd receiver was
added by us and the receiver is in the aft bedroom. The antenna wire for the
2nd GPS follows about the same path as the original Amel-installed GPS
antenna. The antennas do not seem interfere with one another and the sat

Hope this helps.

A good GPS antenna is tolerant of moderate obstructions. I installed
my AIS GPS antenna behind the nav station against the hull on the

from big ships with high antennas. It has worked with two different

Eric & Richard,

VHF is line of sight and rarely bounces. Mounting at the top of the
main
mast gives you around 10 miles further reach than mounting on a
rail. The
"range gained" formula is: 1.17 times the square root of the
additional
height in feet = additional range in nautical miles. The horizon while
standing on the deck is 3.5 miles...from the top of the mast it is
10 miles.

If you want to maximize being seen and seeing others, go up.

GPS does not need height and will work OK under a dodger.

Eric have you thought about putting it on your port aft rail, or
under the
dodger? We find that our secondary GPS a hand held works well
using its
internal antenna as well as an external.
Your thoughts.

I have a single GPS that feeds the Radio, AIS, and Computer (CAP'N program).  Still don't see why your current GPS can't talk to the AIS.  I do have two other GPS for backup, but not necessary for all three receivers.

Any chance you could use your current GPS signal and feed it to the AIS?  Not sure why you'd have to have a dedicated GPS for the AIS.  I don't see why you can't use your VHF antenna as well, unless the AIS transponder interferes with radio transmission...haven't looked into it, but seems like you could have the AIS transponder disabled whenever you are keying the mic.
 
I'll be interested to hear what you end up doing.

We too use an antenna on top of the mast using a spliter VHF/GPS and get very good contacts with major ships with our receive only unit. AIS is a very good safety device. We prefer using a stand alone display unit as there can be to much clutter on the Furuno radar/plotter in T-stroms.

Bill,

I already had an ais receive only antenna mounted on the top of the mizzen
dedicated to the AIS only.



I have now purchased an AIS transceiver and my question was where do I mount

the GPS dome for the new AIS unit?



Thanks for all of your work, photos and advice on our boats.

Eric,

You will loose a lot of distance with VHF by mounting it low.

Our AIS receiver which currently shares the AM/FM antenna on the main mast.
The AM/FM antenna on SM #387 is identical to the VHF antenna. I used a BNC
"T" to split the antenna wire for the radio and the AIS receiver. I have
noticed no problems with either the radio or the AIS receiver. This will not

work for a AIS transponder, but, I am considering buying a small antenna for

the radio, placing it inside the radio drawer. This will leave the AM/FM
antenna exclusively for the AIS transponder.

On SM #387, the triadic stay is rigged with insulators and the coax cable
from the stay terminates in a coil behind the radio/Hydra drawer. I think it

is too long for proper VHF (300mhtz = 1.6 feet of antenna for one-half of
the signal's total wavelength), but possibly could be used to receive AM/FM,

freeing up the Main Mast AM/FM antenna for your transponder.

Let me know what you do.

Best,

Bill

Hi,
I just changed out my AIS receive only for a AIS Transceiver.
We are receiving ships up to 120 miles away.
However I am wondering where I can mount the GPS antenna on my Amel Super
Maramu #376 Kimberlite.

One side of the stern rail has the HF antenna the other the ships GPS.
The mizzen top has the navtex antenna, a seeme transponder and the AIS
receive antenna.

Any Ideas as to where to mount the antenna.
