It depends. Dolphin changed those chargers 3 times. First was no switch, then an A/B switch, then a selector switch with 10 different settings. 
Here are a few things that may help:

Mikrotik has a wifi extender
Hi Scott,

You made me curious about this Microtik product. Having worked with Cisco's Router OS, I'm not so easily scared off by this stuff, but this must be the worst documented piece of hardware ever! It's like having to read the whole phone book for one phone number. So kudos for you that you found a way to get it working. In contrast the Bitstorm Badboy is idiot proof. A build in webserver takes care of your config. It also does NOT support more then one client unless you buy the other toy from them (Called Unleashed), but as I have a proper router with potentially 4 WAN interfaces I don't care. It does require a bit of setup on the router play nicely with the LTE interface but that is fairly easy if you are into that stuff.
It is a bit of a shame they stopped selling it, even with the inflated pricetag. They do not mention isolating the body but with their standard mounting hardware it will be isolated because of it. They do provide you with a SWR analysis of the supplied antenna.

What surprised me, given your results is that the claimed receiver sensitivity of the Mikrotik is -93dB whereas the Badboy claims -96dB (a factor of 2). Transmitting 27dB vs. 36dB.
From my experience the Badboy does connect quite OK most of the time but congestion makes the connection very often almost useless. In Curacao I had a relatively quiet network and could use Netflix without issues. That is something like 2-4 Mb/s if I recall correctly.
I agree that the 5 MHz is mostly useless also because most public WiFi uses 2.4 only

Re: Wifi extenders and the bonding system

Scott SV Tengah
 

I think it really depends on your use case. We are rarely in marinas and in some of the places we've been, mobile data is quite expensive and generally not truly unlimited. In Hawaii, anchored nearly 1/2 mile offshore, we could easily get wifi from shore as long as our antenna was mounted high. During our 14 day covid quarantine time, we were pretty happy for that.

In any event, I was using a 2.4ghz Bullet model and then a 2.4ghz Alfa model. 2.4ghz generally travels further but is more prone to interference, as some have noted. For longer distance connections, it's usually the way to go.

Mikrotik has a wifi extender product that does both 2.4ghz and 5ghz and can do it with one antenna (Groove 52 AC), but I would not recommend Mikrotik's products unless you have access to a very capable network engineer or you understand how to create interfaces in their configuration software for the wifi wan portion, the local lan portion, create virtual interfaces for each of the aforementioned wan/lan physical interfaces and then create a bridge that connects them. Oh and you have to setup DHCP servers and Clients manually. I had my VP engineering friend do it and I still probably couldn't repeat it. When I first got my Mikrotik Wap AC (internal wifi router), I couldn't even figure out how to connect to the device to set it up! But once setup, it's extremely powerful and reliable. Better than any router I have ever used.

As a side note, I asked on Mikrotik's technical forums regarding case grounding. I was told that the Mikrotik Groove/metal, Ubiquiti Bullet and Alfa ALL have the antenna connector connected to DC- via the circuit board. That means the only way to prevent introducing DC- to your rigging is to either put the whole wifi extender device into a non-conductive housing and mount that or get the plastic version of those devices and mount it via the plastic case. Any other way and you violate Amel's floating ground bonding. And if you don't have a later model a54 or newer, your Amel Mass+/- tester light won't show this leak since prior to later A54s, the rigging wasn't connected to the bonding system and hence the Amel tester light.

Re: Amel 54. Has anyone ever taken the electric diesel tank level meter/sensor out of the tank?

Arno Luijten
 

Thanks all for the replies. The code WEMA S2-1170F makes me think the sensor has a length of 1170mm which sounds about right for the given tank. A good tip about the poor power-supply to the sensor. I'm planning to hook it up to the EVC-C system to get some more use out of these Volvo electronics.
That should be fairly straightforward once I have the cable-harnass for this thing from VP. I'm curios to see if it will send the data across a NMEA2000 bridge. It also means I can remove this silly box in the locker where the diesel filler resides.

I replaced the sensor on Adagio and could not find an exact match (I forget the model number, but it was indeed on a label on the sensor).

I wrote to Wema, they offered a couple of options and  finally they custom built a 20 sensor unit that was reasonably priced and shipped quicky.

I was extremely pleased with how they worked with me and how the replacement part for and works.

Re: Wifi extenders and the bonding system

I will second what Arno says about Marina wi-fi, I have an extender on the backstay, didn’t help with internet performance. Sure it gave me better wi-fi signal, but internet still sucked. After speaking with a few others at the marina, I went with the following solution which works great. You have to supply your own 4G SIM Card and data plan, but this thing rocks and for the price it is a great option.

I did do the same tests as you for connectivity and found the connection quality much better at lower levels and away from the mast.

Re: 175A alternator belts

Lior Keydar
 

Dear Nick

My hull nr. is #18... As I bought the boat, I also had the 175A alternator and it was the same problem. 
There was also  a package from Amel with a replacement to this alternator. Mastervolt 110A and its regulator. In order to install the new alternator, you have to release the Volvo Engine from its place and connect the alternator on the left side of the engine. At this solution, you use the same belt that is used for the sea water pump. 
It is not such a simple solution but if you are interested, AMEL will be for sure able to help you with more information.

Dolphin power 1 battery chargers

Ross Hickey & Donna Hammond
 

Hi team,

Can anyone advise if the Dolphin power 1 - 24v/100amp and 24v/30amp chargers can be programmed to accept Gel batteries.

If not any advise on best charger set up to accept Gel batteries and adjustments to service alternator regulator would be appreciated.

The Gel batteries would also be charged by three 215W solar panels through a Victron MPPT.

Re: Wifi extenders and the bonding system

Are you using the 2.4 GHz or the 5 GHz Ubiqiti? I don't know a dual band Ubiquiti.
I'm using the 2.4 GHz Ubiquiti for over 10 years now in its plastic case without any problems but in European marinas.
Some knowledge about networking is useful anyway, e.g. if you have another router in your network there must be only one DHCP.

Hello 
The new generator was installed in my Quetzal. Now the problem is that the old exhaust outlet is a bit bigger than the old one. The old exhaust is 40mm, the new 50mm. The company that installs the generator suggests to reduce the diameter. Another variant would be to enlarge the fuselage passage, i.e. to replace it. Is there someone with experience

Re: Amel 54. Has anyone ever taken the electric diesel tank level meter/sensor out of the tank?

Stefan Jeukendrup
 

Hi Arno,


I can only tell for my SM2000 #348, hoping that a 54  has a similar solution.
WEMA S2-1170F
It is basically  a resistor divider with reed relays. The float contains a magnet closing one of the reed relays.

I found that the inaccuracy was due to the natural 24V battery voltage changes and the bleeder resistor.
So I put a 12V voltage regulator in series and changed the bleeder resistor value so that there is always a constant 12V on top of the resistor divider.
Then  checked its calibration ( by tank volume/ float position comparison)
It is better now.

Hope this helps you,

Re: Wifi extenders and the bonding system

Scott SV Tengah
 

Arno,

I am not worried about the distant access point's radiation pattern. In almost all cases, it's a simple router like the one you use at home with a low gain antenna. If you look at the link on the previous pic, their radiation pattern is likely similar to a 360deg globe of a 2dbi antenna. 

The simple fact is that I ran a test in a few locations with the new device located on the solar arch, 1/3 the way up the mast on a halyard, 2/3 of the way and then at the masthead. Using speedtest.net and packetlosstest.net I almost always got better throughput and faster and more stable response times (ping and jitter) from the masthead location. Now if you're rolling 20 degrees side to side at a rolly anchorage, then my 25-30 degree vertical beam may miss the hotspot while rolling, but I probably wouldn't be surfing the net if I'm rolling that much. :) If you're at a marina and the access point is less than 40 meters away, the same problem may exist, but at that range, I'll just connect my computer directly to the access point vs. through the outdoor antenna.

Your Badboy is based on a Ubiquiti Bullet M2HP-Ti. Badboy packages it, calls it marine and charges you a multiple of the actual price. I know this because I had a Wirie Pro which did the same thing with the same Ubiquiti device and charged me even more. BTW the "Ti" stands for titanium but it's really aluminum. And it never worked right as they set it up incorrectly and the external wifi antenna would interfere with the hotspot their LTE router created inside the boat. I tested this by sitting right next to a very close access point with the antenna in the same location (and height) as my computer. Directly connecting with my computer resulted in 5x faster speeds. And the signal to noise ratio was much better on my computer. 

I ended up going from knowing almost nothing about wifi to learning a lot. I ended up setting up taking the Wirie Pro apart and just using the Ubiquiti M2HP-Ti with the stock Ubiquiti AirOS firmware and pairing it to a Mikrotik WaP AC router operating on 5ghz. The latter made all the difference but it took me a year and the help of a VP of Engineering from a well known Silicon Valley company to set it up! Mikrotik's RouterOS is not for non-network pros, I've learned!

Sadly, the Ubiquiti died after 2 years and now I'm looking for the replacement since they're no longer sold. My Ubiquiti and the subsequent Alfa are all connected the same way from the external device, which as you note, has the WAN (wide area network) part of the wifi system to my Mikrotik "inside wifi" system via a Cat7 shielded ethernet cable that delivers both power and data. The Ubiquiti Bullet, Alfa Tube and Mikrotik Groove/Metal 52AC are all connected this way.

The Wirie Pro was put in a Pelican case which was mounted on the arch, so isolated in that manner. I didn't get a chance to test whether the Bullet was case grounded, but now I think about it, the Bullet did show a lot of corrosion on it. Perhaps you can stick a multimeter between an in-operation Badboy/Bullet case and battery pos and battery neg. I'm curious whether you'll see 24+ volts.

I've taken it out to check how dirty my tank was. Very easy to do but I have no idea what the model number is. 

There are two inspection hatches on the top of the tank. It's the forward hatch with the wires going to it.

Re: Sand Blasting

Patrick McAneny
 

Joel, Bill pointed that out to me ,but what he sent and I read ,left me wondering if they were referring to using high pressure above the waterline,which they stayed several inches below. In any event ,as they did not blast it to the point that they even removed all the paint ,I cannot see how any water could of penetrated the gel coat ,certainly does not appear to be the case and once the sanding was done the hull was smooth as can be and appeared completely dry. I suppose if the operator was not careful ,damage could be done ,perhaps that is why they stopped short of removing all the paint. The work is being done at Haven Harbor in Rock Hall and they have a very good reputation for doing excellent work. I will probably  not apply the barrier coat until spring ,with Covid ,I think we will probably sit this winter out .
Thanks,

Hi Pat. Before you paint the bottom or apply any coatings, be certain to have the bottom checked with a moisture meter over its entire surface. It states in the Amel owner’s manual in the third section of the users guide several things about using high pressure washing below the waterline. It says to never use more than 1130 psi/80 bars of pressure, always from a distance of more than 8 inches/20cm, and at an angle of 45 degrees and never perpendicular. It is generally recognized that using pressure above 2500 psi is detrimental to any polyester or epoxy resin fiberglass laminate.
 
Be sure that you have an acceptable level of moisture in the laminates before you proceed to refinishing.
 
I have seen first hand the detrimental effects that extreme high pressure washing can produce and it is never pretty. If you would find it helpful, give me a call after you get your moisture readings and I’ll give you some advice based on experience that should be helpful.
 
All the best,
Joel

James, There was one area ,about 8 sq. inches where there must have been a void where the first or last layer of fiberglass was partially removed ,the manager said that sand blasting would have opened it up as well. It will be a simple fix and I will be doing about three or four coats of barrier coat . There is no other area where all the paint was removed ,so no damage to the gel coat,after a light sanding the gel coat is as smooth as can be. The yard did not consult with me on power washing as opposed to sandblasting ,which concerned me ,but I am glad they went with it.

Pat,
 
   This sounds like an interesting option to me and apparently there was no damage done to your gel coat.   I like the fact that you avoided using harsh chemicals.  You also checked your boats bottom for loose putty and voids in this process whether you realize it, since 5000 PSI can take anything off that is not well attached and can open up voids near the surface!  I had the bottom of my boat checked with an ultrasound during the initial surgery looking for voids, delaminations etc. and non were found.  That would not be the case on many non Amel hulls.  It seems that Amel does a very good job with their laminations in getting out all of the air, especially at the critical gel coat interface.  Really glad that this worked out for you.

What they did was to use a 5000 psi powerwasher with a rotating turbo head which blasted most of the paint off . I missed that part ,but while I was there a workman used a 7" orbital sander with 60 grit to take it the rest of the way down to the gel coat. He did a 20 sq. ft. area in about 15 minutes . So it should take about 9 hrs of sanding. What he did looks perfect and no concerns for damage to the gel coat.
