David, since you seem to be so interested in having an external LTE antenna (which I've never found the need for), might I suggest you get one of those hockey-puck portable hotspots?  I've had good luck putting it in a waterproof bag and sending it up the mast on a halyard when I want to use it and bringing it back down to charge.  That would also give you easy access to the SIM card. I stand by my original recommendation as a better, permanent solution.

Since my original post I have read the responses (thank you all) and trawled the web.  There maybe others like me treading this path so I thought I’d share what I’ve learned/concluded so far.  One caveat, I’m a very modestly technically literate sailor, definitely not an RF, electronics or networking engineer. If I have made any silly errors please let me know, I’m keen to learn.

 

I’m not currently aboard so doing much of my layout thinking from memory.

 

To recap the requirement: I’m going to be cruising the Mediterranean and want to be able to access the internet. Ideally, I’d like to able to get weather forecasts whilst coastal sailing offshore/between islands, subject to the limits of 4G coverage of course. Budget: Conscious that cheapest isn’t always the best, I’d rather spend a bit more to get performance and quality than save a bit but regret it later.

 

 

(a) Prioritise 4G/LTE over Wi-Fi. A number of people have commented how Wi-Fi systems are often overloaded and slow, that 4G provides better data rates.

 

(b) It’s more cost effective (and satisfying) to assemble my own system than buying a turnkey setup (e.g. DigitalYacht, Red Box etc). I’ve found a couple of exceptions to this but they have a major downside with the SIM card being badly located – more on this later.

 

(c) Antenna

Use an external omni-directional antenna (vs. one down below).

 

Keep the cable run from antenna to modem/router as short as possible to minimise losses. Mounting the antenna high up is less important than keeping the cable run short. This leads me to thinking possible locations for the antenna are: mizzen spreader / aft rail or arch / between the backstays. Least attractive is on top of the mizzen mast due to the distance.

 

Use LMR-400 coax cable if the cable routing permits.

 

To get the benefit of 4G/LTE a MIMO antenna is needed. The Poynting OMNI-402 gets very good reviews on build quality  but it’s expensive at UK£290 (https://www.solwise.co.uk/4g-antenna-omni-402). One or two articles seem to challenge the benefit of a MIMO antenna https://seabits.com/poynting-omni-antenna-testing/ and https://novaroundbritain.home.blog/2019/10/18/internet/ and maybe a simpler OMNI-291 (UK£144) SISO antenna would deliver pretty much the same performance (still very good build quality) but at half the cost.

 

I have looked at a couple of integrated solutions such as the WEBBOAT 4G LITE from Glomex (€609) https://shop.glomex.it/en/webboat-coastal-internet/660-it1104-webboat-coastal-internet-4g-wi-fi.html and Solwise QuSpot omni LTE/4G (UK£452) https://www.solwise.co.uk/WI-AX11S which have the antenna, 4G modem (SIM card) and router all integrated into the antenna dome. These look cost effective, eliminate antenna cable losses and look simpler to install however it means regular access to the SIM card is a problem if installed on a spreader or between the backstays. Why the need for SIM card access? From what I can understand there’s a need to either return to the UK with my UK SIM card every few months to maintain the EU roaming or to buy a SIM card in each country as the EU roaming expires. Either way regular access to the SIM card is needed.

 

(d) 4G Modem/Router

The Teltonika RUT 240 (UK£124) https://www.solwise.co.uk/4g-routers-rut240.html looks like it’ll do the job. The LAN port means I can one day connect an NMEA bridge should I want to. One could spend a little more and get the Teltonika  950 (UK£166) https://www.solwise.co.uk/4g-routers-rut950.html as this has 3 LAN ports which leave room for more expansion.

 

Location of the router will be determined by where the antenna cable enters from above (I’m not aboard at present). I’m assuming with a GRP structure WiFi propagation from the pilot berth or aft cabin (likely router locations) throughout the boat should be adequate, certainly to the saloon and aft cabin.

 

(e) WiFi

Assuming marina/cafe provided WiFi data capacity will be usually poor I may still buy a WL-Patriot-DB (UK£87) https://www.solwise.co.uk/wireless-Patriot-DB to at least try in each location. This would plug into the WAN port of the router. It’s powered over ethernet which simplifies matters. I’d either locate it somewhere inside or stick it outside temporarily via a porthole maybe.  It’s IP65 rated so if its outside in a rain shower it should be okay, but I’d be reluctant to mount it permanently outside.

FWIW I appreciated the original post. I bought Julie's first book and will consider buying the sequel. I had some minor quibbles with the first book, but in general, it was a pleasant read. I should think it pertains to all of our interests (and benefits us by raising Amel's profile).
Not sure how this is any different from others advertising their Amel-adjacent pursuits.

Good catch Gerard! I meant the Rod Antennas in your terminology of course. I was referring to the fact that rather than a simple 1/4 wavelength antenna that is Omni directional (like our sailing VHF/AIS antennas) or the ones you see on home routers, the Rod ones are relatively flat in the horizontal plane. Your highly directional antennas of course are much better but then need to be aimed at the source as your diagrams show. Sorry for the confusion. I’ll blame it on my iPhone!  LOL.

Jorge, I use a UK three SIM for when I’m travelling in Europe and they have a wonderful roaming plan. I get about 20G for 15 British Pounds (you can even get unlimited for about twice that). and it works in over 90 countries including many of the islands in the Caribbean (not Bermuda or Mexico though). I got it on Amazon and I do the top ups from PayPal so it works even though I don’t have a Uk credit card or address.

Re: vetus coupling removal

MICHELE LUCCIOLA
 

Hi Herbert,
I did this job the last year....the only suggestion I can tell you is to remove the  gearbox with the  the vetus coupling installed (just dismount the fixings on the flange on the engine); in this way you can easily remove the axle on a bench because the space to work with the engine installed is very unconfortable. In fact also if you want to use an extractor (I did one with long arms) you have to pull the engine back to have a little bit of room....anyway you have to use not gentle manners to have a good results...but is better to work on a bench that in the engine compartment...in this way you can also change the  seal of the gearbox easily once removed the little shaft.
Just for your use i attach a pdf in which there is an explanation of the job....but I prefer to put the gearbox out of the boat with the shaft attached and to do the job in a confortable and safe way...
regards
Michele

Many thanks for that. I was intending to do something along those lines. A photo would be good if you don’t mind. I may struggle to find 5200 here in Cariacou so it may have to wait a bit. I am surprised that Amel did not design a way to stow the tiller in that obvious location!

Hi Paul,

I used a piece of pontoon wood (whatever that hard-wood is called) and cut strips of 30-40 cm from it. I then put these on the bulkhead vertically so they would create a hook to prevent the emergency tiller falling off the small ledge.
The bulkhead is not very thick, 12 mm or so. So to fix the wood I used screws of only 10 mm sticking out of the pontoon wood. To make sure the things would hold I put 3M 5200 compound between the bulkhead and the wood. So the screws were more there to keep the wood in place during the setting of the 5200. Make sure you sand and de-grease the surface of the bulkhead at the point of attachment. 3M 5200 is incredibly strong so I have no worries about detaching. It has been fine for 1.5 years now. I also put some small blocks of wood on the ledge at either end of the tiller to prevent it from sliding left or right. I can make a picture if you want.

Re: Mobile communications - 4G, WiFi

Those directional antennas generally have a +/- 3  degree plane off vertical. Using the old (and very handy)  1 in 60 rule (1 degree at 60nm is equal to a distance across that arc of 1 nautical mile or 6000 feet).it’s easy to calculate that if you are say 1/10 mile from the source antennas, then you can be as much as 30 feet off plane and still get a decent signal. ( 6000/ 60 / 10 * 3 degrees = 30’)   I’m not sure that I’d put the directional antenna on top of the Mizzen as the extra height isn’t doing you any favours up really close  but Eric has a good solution (at say 15’ off the water) as that would easily allow you to hit an antenna at that elevation but also up to 45 in at that distance (the further out you are, the less it’s a problem- 1/2 mile would be 150’, 1 mile is 300, etc. ’Anyway, unless you are sitting right on top of the source antenna, in which case your computers would likely get Wi-Fi anyway, it won’t make much difference where you mount it.  The range is still likely to be fairly close just because of the signal strength so unlike VHF (or AIS),  boosting your antenna to get additional line of sight isn’t going to make much difference anyway.

You bring up a good point about the DHCP configuration.  The easiest way to fix it is isn't to turn off DHCP on one of them, it's to ensure they assign from separate IP ranges and ensure one is plugged into the uplink port of the other.  Then the downstream router will get an IP from the upstream one just like any other device.  I recall this was very easy to set up with the Mikrotik routers.

Depending the conditions I use 2 different kinds of antennas.
The usual rod antenna has the characteristics as shown below:
<WiFi-Rundstrahlantenne.png>
360 degrees horizontal but only a small angle vertically.
That means the antenna should be mounted as near as possible to the horizontal line to the access point.
However a directional antenna has this characteristic:
<WiFi-Sektorantenne.png>
That is nearly same quality horizontal and vertically.
So if you know the direction to the access point take this one.

Another thing to know: My Bullet as well the Groove are routers. When you attach them to another router in your network on board the boat then only one router in the network can be configured as DHCP server which handles the IP addresses in your network. Otherwise the network is blocked.

Correct, the bandwith is often very poor. It is a little better at night times when most users are asleep. But a nice antenna helps a lot. When you have a poor signal strength you have also a small bandwith. That is the way the WiFi protocol works.

I have the Bad Boy Unleashed WIFI extender system Amel offered as an option on the 55.  It has worked well enough but I have found that in the Med, WIFI is usually useless because of lack of bandwidth.  I Found that in most marinas I visited the WIFI was overloaded at the times I wanted to use it.   Restaurants WIFI I found no better, typically worse.  So I installed a 4G SIM card in my Redbox router (Mailasail) which gives me WIFI via a 4G LTE connection on the boat.  In most countries in the Med, cheap 4G SIM cards are available which typically give you 10G or more for $10.  I found this solution cost effective and much less stressful than trying to get a decent WIFI connection.  It requires you to get a new SIM card in each country, though.

You bring up a good point about the DHCP configuration.  The easiest way to fix it is isn't to turn off DHCP on one of them, it's to ensure they assign from separate IP ranges and ensure one is plugged into the uplink port of the other.  Then the downstream router will get an IP from the upstream one just like any other device.  I recall this was very easy to set up with the Mikrotik routers.

The usual rod antenna has the characteristics as shown below:

360 degrees horizontal but only a small angle vertically.
That means the antenna should be mounted as near as possible to the horizontal line to the access point.
However a directional antenna has this characteristic:

That is nearly same quality horizontal and vertically.
So if you know the direction to the access point take this one.

Another thing to know: My Bullet as well the Groove are routers. When you attach them to another router in your network on board the boat then only one router in the network can be configured as DHCP server which handles the IP addresses in your network. Otherwise the network is blocked.

Hi Paul,

I used a piece of pontoon wood (whatever that hard-wood is called) and cut strips of 30-40 cm from it. I then put these on the bulkhead vertically so they would create a hook to prevent the emergency tiller falling off the small ledge.
The bulkhead is not very thick, 12 mm or so. So to fix the wood I used screws of only 10 mm sticking out of the pontoon wood. To make sure the things would hold I put 3M 5200 compound between the bulkhead and the wood. So the screws were more there to keep the wood in place during the setting of the 5200. Make sure you sand and de-grease the surface of the bulkhead at the point of attachment. 3M 5200 is incredibly strong so I have no worries about detaching. It has been fine for 1.5 years now. I also put some small blocks of wood on the ledge at either end of the tiller to prevent it from sliding left or right. I can make a picture if you want.

Cheers,

Paul,

We drilled right through and put a small (1mm) bolt through with washers each side  and we sealed it [so very small hole]. As to the height - I am not on board and will not be until May but it is not difficult to measure from inside and calculate the height for the hole.

When I’m on board again I can measure up from the sole of the lazerette but I expect you will have done it by then.

The bolt holds a canvas type pair of straps and the steering gear is held tight.

Thanks all for the feedback.

 

My idea was to fix a couple of steel bars to prevent them from falling out. These would be mounted just below the lazarette shelf, rotating up to prevent the tiller from falling out. However, I do not know how far into the GRP I can drill, so that info would be useful. Peter, you say you drilled through – how deep? Is it necessary to drill all the way through? And if so at exactly what height?

 

Cheers,

Paul

On Carango we use the little shelf on the forward bulkhead of the lazarette we drilled through the bulkhead into the rear cabin taking care that we drilled through so the holes were behind the ledge above the head of the double berth and out of sight. it was not too difficult and a works well.

Hi Paul;

 

I did think about this issue. My thoughts were that there are so few cases of the tiller being needed in a 54, as far as my research showed, that the location allocated by Amel would be adequate. In the unlikely event of a steering issue, we would be well motivated to remove the items required to get to the tiller. We may revisit this issue, if we hear sufficient arguments to the contrary.

 

Respectfully;

Hi all,

 

For the A54 I have yet to hear of any successful remedy to the problem of emergency tiller storage, and so far mine has been lying at the bottom of the stern lazarette which is far from ideal. Having just tried to figure out a good place I can see that on the narrow shelf top forward part of the stern lazarette there is a good place (see attached photo) but it needs something to keep in in place. Does any one know how thick the GRP is there before I start drilling?

 

Cheers,

Paul

Hi Ryan,
When I had Kimberlite made Amel mounted a bar between the backstays for our KVH Sat phone. Since we have the go- and no KVH we have extra space on the platform to mount the Groove.

Hi Everyone,

I'm going to be cruising the Mediterranean for the next few years. For internet/email access my primary channel will be mobile/4G although I'll use WiFi when available. Consequently I'm looking to install a good antenna/router system for 4G and WiFi.  I see there's one or two ready assembled products available from people like Digital Yacht or I could buy my own components and maybe get more bang for my Euro plus get even more job self-satisfaction!

Does anyone have any experience they can share?
