Re: Predict Wind

Finished up our trip to Brunswick and used predictwind along the way. I can verify that 12-15 miles out I got a signal with ATT. Using predictwind for updates was fun. The European model ECMF won the prediction although I need to sail better or adjust my polars as we got in behind the prediction time. They did call for some northerly wind but under predicted speed and wave height. Of course it turned a tad uncomfortable at night, all through the night. Overall a pleasant trip and our first overnight sail with just the two of us.
Happy New Year to All!

I am just saying that to be on the safe side as, reading my insurance contrat, this is 1 think they mentioned.
Of course if you are only 2 and the boat is made for 8, this is lots of weight saving!

Aqua Clean tablets do indeed contain chlorine in the form of Sodium Dichloroisocyanurate. This molecule allows for very slow release of chlorine into the water. Free chlorine can indeed be measured in water so treated. It seems to provide fairly good anti-microbial treatment without much chlorine taste, but since free chlorine can be be detected, I would not consider it to be safe for RO membranes. That said, you may get away with it, but I would not consider it to be bullet-proof.

Hello all,

 

To preserve fresh water in the tank, I use a product called “Aqua Clean”.  It is said to kill bad marine organisms and to preserve the water for 6 months.  Best is that it does not contain chlorine and so will not hurt the membranes when you back-flush, and it has no taste.  It is widely available everywhere except in the USA.

Re: [Amel Yacht Owners] Atlantic Tower Arch Installation, Alternate Method

Patrick McAneny
 

Mark, I was the first one to install an Atlantic arch on an Amel several years ago , and I don't remember them having an installation video. So I don't know what they show , but what you describe sounds like the correct steps. You would need to preload it just to get it to fit between the gunnels , and would need to place it in position to mark the hole locations. I remember they had a range of inches to preload , like between 2 to 6 inches , so I loaded it at 4 , midway , if I did it again I would have loaded it slightly more , maybe an additional inch. One benefit of these arches are , that if you needed to , say to fit on a travel lift , you could unbolt the front legs in a couple of minutes and swivel the arch back and down over the transom. I thought the arch was taller than it needed to be , so I cut several inches off the legs, I am 6'1" and still have plenty of headroom .  I think it looks better and reduces the leverage arm , especially with the dinghy on the davits.
Good Luck,
Pat SM#123

Hello All,

I watched the installation video on AT's website and read everything I could find on the Owner's group regarding the installation of the arch.  After sleeping on it, it occurred to me that it may be easier (given the manpower) and more forgiving (easy to make adjustments before drilling) if I assemble and pretension the arch, lift it in place, adjust to my preference, mark mounting holes, remove arch, drill, pot the deck, re-drill, bed and install.  Dos anyone see any reason why this wouldn't work, or problems with the method?  When they open for the day, I'll call the company for their feedback as well.

Hi Alan

Thx a lot for Your explanations. That were exactly the informations I needed.

Please allow three more questions:

- do you have Pictures by any chance of Your wiring in the Lazarett?
- the AMEL pre-installed wire from the nav table to the Lazarett on my SN is a "big fat" one. How did you mecanically attache it to tiny small screw of the tuner?
- yes, the SN is a 12V system. Can you give me some guidance towards the "relay" I have to look for. I have experience at all with relays.

Again, thank you very much for Your time and for sharing Your Knowledge.

Best - Daniel

Hi Alan,

I’ll  have to look at my setup.

 

On another subject, I just had Kimberlite  re-rigged in Martinique. I had them remove the insulators on the triadic as it was used for my Weatherfax which is now history. I removed the coax and all is well. However there is another piece of coax in the mizzen, and in the aft head it is marked BLU—do you know what that means- I did not have a chance to trace it back to the nav station before I left Kimberlite. I thought it might

 have been for the Navtex which was a part of the Weatherfax but required a separate antenna.

Nope Eric,

 

The green/yellow cable marked BLU runs from the copper strap in the lazarette to a ground connector at the navstation where without an SSB (BLU) installed it is connected to the bonding wire. I disconnected the BLU cable from the ground/bonding connection and connected it to the earth on the transceiver...yes the transceiver.

Then at the lazarette end I cut this cable and connected both ends to the ground on the antenna tuner. So, now we have both the transceiver ground and the tuner ground connected to the copper strap in the lazarette which in turn is connected to the SSB ground plates on the skeg.

This is what the ICOM manual instructs you to do.

The transceiver and antenna tuner MUST have an adequate RF ground connection. 

 

The transceiver is NOT connected to the ships bonding.

 

BUT because internally the ICOM 12v -ve is connected to the ICOM ground, the negative side of the power supply must be isolated from the ships power -ve otherwise there will be a circuit through the seawater from ships negative to ships bonding...which is not allowed in the Amel system.

This can be accomplished by using an ISOLATED 24-12VDC converter (expensive) or with a non-isolated converter (inexpensive) and a relay in the -ve 24V supply to the converter such that this connection is only closed when the SSB is on. The small amount of time the SSB is on is nowhere near enough to cause a problem.

Re: [Amel Yacht Owners] Re: Bilge maintenance

I agree with the Dessalator rep that RO processing can remove essentially all bacteria and viruses. 

The problem is you can only be SURE that it will if you run a bubble point test to make sure there are zero faults in the membranes, seals, and housings. When I used RO membranes in the phamra business to make sterile water we had to test them every membrane change and maintenance cycle.  They did not always pass.

This is why my Dessalator manual recommends adding chlorine to the tank--just in case.

When I have been in crowded harbors with the possibility of sewage contamination there has never been a pressing reason I HAD to run the water maker.  I just wait until I am somewhere safer. We tend not to stay in places like that for very long!  If for some reason I had to make water, I would add chlorine to the tank, and then not worry about it.

My basic rule is: If I would not swim in the water, I don't make drinking water out of it--even if the RO unit SHOULD be able to do it safely. The risk of having a serious problem is very, very small, but it is still one I don't need to take, so why?

We never add anything to the fresh water tanks, except RO water.  We avoid running the RO system in harbors, and any place we even suspect might be polluted. We routinely keep the tank as near to full as we can.  The only exception has been when we are in a boatyard for longer than a tank of water lasts, we eventually have to break down and put tap water in.

If I was anyplace I worried about any kind of pathogen in the source water, I'd break my own "rules" and would chlorinate the tank just to be safe.

Hello Daniel,

It seems to me that in addition to those little wires you speak of, you need a solid grounding wire between the transceiver and the ground plane connection in the lazarette.

 

Look at the diagram on page 49 of your manual

 

Page 51 says :

 

The transceiver and antenna tuner MUST have an adequate RF ground connection. Otherwise, the overall efficiency of the transceiver and antenna tuner installation will be reduced. Electrolysis, electrical shocks and interference from other equipment could also occur. For best results, use 50 or 75 mm (2 or 3 inches) wide copper strap and make the connection as short as possible. Ground the transceiver and antenna tuner to one ground point, otherwise the voltage difference (in RF level) between 2 ground points may cause electrolysis.

 

 

In our SM the yellow/green cable from the lazarette ran all the way to the nav station. When we installed our Icom 710, we disconnected this cable at the nav station and connected it to the transceiver ground....at the other end we cut the cable and connected both ends to the tuner, which is connected to the copper strap in the lazarette.

 

This is NOT the bonding that the saltwater pumps etc are connected to.

 

VERY important thing is that you use ISOLATED power to your transceiver because inside the ICOM, the -ve power line is connected to ground. 

Your SN is a 12v system I think (?), if so and you have the power directly from the breaker, you need a relay in the 12 v -ve line that disconnects it from the transceiver when the power is off - you need to turn it off at the breaker, not just the transceiver.

If you have 24V then you need an ISOLATED 24-12v converter, or a relay in the 24V-ve feed to your 24-12v converter for the reasons above.

If you don't isolate that -ve power line, it will lead to electrolytic corrosion issues. 

Good luck

Happy New Year

Hello Kent and Bill,

overloading a vessel not only changes its stability but also brings more power into the structure and masts/rigging.
A big overload could result in stringers/bulkheads breaking when the vessel hits the waves in heavy conditions, possibly breaking shrouds strands too.
The Super Maramu has a light displacement of 15.3 tons (with masts, sails, running rigging, some mooring lines and fenders). The tanks (water and fuel) take 1.5 tons.
You should not load with more than 2.5 tons (including crew and life-raft...).

Stay safe and have all a happy new year!

Olivier
