Re: Additional webbing above tack on Q-Sails Genoa Question

 

I do not have a photo. About 6-8 months ago I sent this photo to Emerah at QSails and suggested that he add it for all Amel owners:

Greetings!

When we helped mounting the new Genoa from Q-Sails on a friends SM I noticed that the sail had an additional webbing above the tack going horizontally across the luff. This allowed to lash the bottom part of the luff closer to the furling profile. I thought this was very clever. Our Genoa made by a different sail-maker in the US does not have this. The bottom 3 feed below the opening where the Genoa's luff is feed into  the groove of the profile is always pulled out. Maybe it is not supposed to to be feed into the grove.
Does anyone have a picture of a Q-Sails Genoa with the extra webbing above the tack?
Any recommendation how you lash the tack of your Genoa to stay in the bottom part of the groove?
Or should the sail not be feed into the bottom 3 feet of the profile?

Thank you in advance for any feedback

Hi Bill,
         This all came about due to taking a detour into the Amazon for a few months. Loads of silt in the water, even sixty miles out of the delta the water was still chocolate brown.
When I came to Ireland I was chatting to some of the local fishermen who told me it was quite normal for them to change out the seawater pumps on their trawlers as they often will plough through sand to get into various bays where they can get a good haul of prawns.
Am I right that the pump on that Yanmar would have been a Swedish make - Johnson?
Best to You & Judy.

Re: randomly occurring increases of engine temperature

 


Raw Water Pump Chamber Wear:
That is an interesting point. I searched for the diameter of new raw water pump chambers and could not find any dimensions for the Onan/Sherwood 702 pump which is on most Onan generators, the Volvo engines, and the Yanmar engines. I think this may be something that an owner would want to know. If any of you happen to have new pumps as a spare, please measure the inside diameter of the raw water pump chamber and reply.

Impeller Blade Wear at the Tip of the Blade:
I have never measured the wear to the inner wall, but have measured wear to the impeller blade tips and found a reduction in diameter of a little more than 2mm. This wear happens for 2 reasons: Hours of use and the cleanliness of the inner wall. The inner wall of a seawater pump will become crusty to the touch from the buildup of minerals. The more abrasive the inner wall is the more wear. The inner wall should be cleaned each time an impeller is changed with a combination of 600 grit wet/dry and Scotchbrite pad.

Sadly, many people think that impellers only need to be replaced when the blades tear off and the engine overheats.

       I had a similar problem. with the Yanmar engine in my SM for almost a year which drove me mad. Finally I bought a new sea water engine pump more out of desperation than discovering the actual fault.
When fitting the new pump I had the old and new pumps sitting together in the cockpit.  I thought I was imagining it, bit when I checked the old one with my callipers the chamber that houses the impeller was almost 2mm wider than the new one from wear. 
Fitted the new pump and the temperature returned to and stayed at 80C.

Re: Solar panels stainless steel mounted vs soft panels

Slavko Despotovic
 

Bellow is set up I have tested during first year of ownership of Bonne Anse. It is very improvised but gave me some result. This are all together 150W at 24V, From May to September it generated 15-20% of my needs. Between 650 to 1000Wh. For next season I will be installing two flexible solar panel 150W 36V so it will generate twice the energy. This position I found very good. Most likely I will add two 180W flexible bellow the boom in direction to mast.

Re: 24V+ Isolated Ground Leak

 

Porter,

I believe that Amel did not start connecting the rigging to binding until the A54 production. Paul has a late-model SM, and possibly it began then.

Alan,

In my earlier post, I thought that I had identified the problem circuit as being the instruments/devices connected to the Navigation Breaker as I was not seeing house bank voltage when testing with the breaker off.  The problem is however, I was doing the testing on the Nav Bus behind the navigation station.  When I test elsewhere, I still have house bank voltage on the positive side.

My situation is basically identical to Marks’.  My Masse Light is working, When I install a jumper wire from the positive terminal on the Nav Bus to bonding and turn the Masse Light to + the light shines brightly.  Likewise, when I do the same using the negative terminal and turn the Masse Light to - the light shines brightly.  However, with no jumper wires installed, I get no illumination at all, and I have checked in the dead of night.

So as you said, there has to be a connection somewhere, but also like Mark, the leak has to be small if the Masse Light does not illuminate correct?

Is there a way to check current flow through the bonding wire with a multi meter?  If so, what is the procedure?

One last question.  I searched for the abbreviation “ve” but could not find anything.  I assume it means voltage but is there anything special about using ve vs V?

Re: 24V+ Isolated Ground Leak

Alan Leslie
 

Hi Paul,

In reverse order I write -ve when I mean negative....

Current through the bonding wire....you can disconnect the wire, put your multimeter on the lowest current range (you probably will need to move the red plug on the meter) and measure between the bonding wire and what ever it was connected to.
I doubt you'd be able to measure anything if your MASSE light doesn't light up....it's probably microamps....

The foolproof, and tedious way to find it is to first unplug all your AC to DC powered devices, if you still have the Calpeda pump and it's bonding connection, and see if it goes away.
Then disconnect the -ve on each DC device which has a bonding wire .... this should be ONLY devices that have metallic contact with seawater. .. until you find the disconnection that makes the stray voltage go away. In my case above it was an AC device that was causing the issue, but I have had it with macerator pumps also. 
As I said before, if you find a DC device that has a bonding wire and ISN'T in contact with seawater, remove it.

Porter's question below.....

On an SM (could different on a 54) the rigging is not connected to the bonding or battery -ve (unless someone has deliberately made that connection)...you should read no continuity between the rigging and bonding, or rigging and battery negative.

In any event, your issue is that there is a connection, somewhere between 24V -ve and the bonding.

Trust that helps

Re: 24V+ Isolated Ground Leak

A year or two ago the Masse -ve lit up faintly…
I had fun finding a leak. Eventually diagnosed and fixed by cleaning the built up carbon from the Bowthruster motor and the main anchor windlass.  
The light came on the negative test but only faintly. The builtl up carbon  linked the motor negative side to Bowthruster case which is bonded to the rudder anode.
Ditto with windlass.
Worth checking.

Re: B&G Sonic Speed sensors replacement

Jason Rutledge
 

Michele,  I did this last year with Gary Silver.  It wasn't hard.  The sensors in the boat and keel, were just pushed in.  We carefully drilled a small hole into each broken sensors (this was the hard part) and then put a screw in the sensor.  There is a hard piece of something inside the sensor, that took some patience to drill through,  We made sure the cables were loose and pulled on the screws and the sensors came right out.  I believe Bill Rouse has a write up on it....

Bob,
This is a good idea. I agree that in the tropics running the generator + water maker+ Bat Chargers can cause create a lot of heat. Increasing the air flow can only help. Also adding and pointing a fan to the high pressure pump of the water maker is something I have in my list.

Re: Lithium Battery BMS

Paul Osterberg
 

Juan 
I bought 16 cells from RJ in China in total 540 Ah 24 volt (2700 USD free delivery, Portugal), opted for a high quality BMS MasterLi including high quality Contactors ( 750 A continius load) Cost for BMS contactors Busbars fuses etc close to 2000 USD. The BMS workshop with a AUX lead acid battery, taking  the charge from what ever you  charging your Li pack with when the charge relay open, so no risk for regulators it always work towards a load. I use my Victron MultiPlus who is controlled directly by the BMS, My old original Dolphins charger also works without problems, of course Solar MPPT works great as well. For the Alternator I used my previous installed Balmar external regulator works good. The BMS cut the field line a few seconds before the charge relay opens, that to protect the Alternator. The good thing is if the BMS or Li pack malfunction I can still run communication and navigation from my AUX battery. Have had the system now for 6 month, very pleased so far. But part of my satisfaction is due to 1,4 kW of solar power. Do all the cocking on induction. Run the calorifier from the inverter.

Re: Hypalon-RIB 250cm storage

To be able to store the dingy in the aft lazarer, you can’t have a solid bottom. You have to be able to fold it.

Here is how we store our dinghy. Having a slide we mount over the aft it is super easy to launch it and get it back up again.
We have hade this system for 16 years, sailed Europe-Caribbean back and forth and many years in The Med. We do have a cover that we put on during lo g distances over open sea to prevent it to be waterfilled.

Not a very goid picture but it is what I have availeble right now.

Hello Slavko,

Would you get it in the lazarette? I doubt it.
We have a 2.6m Highfield RIB and we store it upside down on the aft cabin roof under the mizzen boom, bow facing aft. It JUST fits.
We had a custom elasticised Sunbrella cover made for it and it's held down with webbing straps to the rails on the cabin roof. 
We have sailed across the South Pacific with it like this and have not had any issues even with white water coming over the boat.
