@ Mohammad, et all

I have seen you installed the fix prop last year. How was the installation? Exactly as Bill believed?

How do you removed afterwards without puller? Was it easy to take it off?

 

Ruedi,

The Performance differences between an Autoprop and a fixed prop are complicated.  While motoring at cruising speed and on up to full throttle, the differences will be trivial, becasue this is the power range the fixed prop is optimized for.  At lower boat speeds, the Autoprop will be somewhat more fuel efficient by allowing the engine to fully power up at lower RPM.  In other words you will reach the same boat speed at lower RPM. This might matter to people who motor sail a lot.

The Autoprop is "fussier." It will show significantly reduced performance when fouled compared to the same level of fouling on a fixed prop.  (Although ANY fouled prop is a real fuel suck!)

Any feathering type prop will be MUCH better than a fixed prop at low sailing speeds. This will matter to some people more than others.  If you are the kind of person who starts an engine whenever boat speed drops below 4 knots the fixed prop has no real penalty here, but if you refer to sail along at 2 knots instead of listening to the engine, the lower drag of Autoprop (or any other feathering prop) matters--a lot.  

I find the behavior of the Autoprop in close quarters maneuvering to be less predictable that a fixed prop or a MaxProp, with more of a lag between throttling up and getting the boat moving, and less of a linear relationship between throttle and thrust.  But, to be fair, this might just be a result of me having far fewer hours on an Autoprop equipped boat.

You can not expect to remove a fixed prop without a proper puller. If it is so loose it just comes off by hand, it was definitely not as tight as it should have been.

Re: New sails [cross-cut * Nautosphere VOYAGER v tri-radial HydraNet]

Nick and all,

   Q-sails delivered my new Hydranet main and Genoa today.   Both sails fit well and the workmanship looks excellent. I was charged exactly the amount in the original quote with the exception of a small 70 Euro delivery fee to Marmaris, Turkey.  The original agreement was for us to sail Sueno to Izmir so an added delivery charge was to be expected.  The pricing was very good and my sails were delivered on time.  I was told a bit about the supply chain issues which can be a big problem when it comes to delivery times on some sails.  In my case, I wanted to keep the original Amel crosscut sail layout and the Hydranet crosscut fabric was available.  The Hydranet Tri-radial material  for instance is in high demand and production is very limited so I would urge patience if that is the material your sails will be built of.  Keep in mind that Q-sails does not manufacture sail cloth and they cannot build sails until they have the materials.  These two new sails now give me a complete matching set of Hydranet sails from Q-sails since Q-sails built me a really nice Mizzen back in 2018. I learned today that Q-sails built almost 2000 new sails last year, I had no idea that they were that large of an operation.  I will be going back to them for a mizzen balloner later this year.
   
   We are really enjoying Turkey...

Hi David,

I bought Amelia an Amel 54 (2006) in 2017. She came with the original Hydranet sails,  has sailed two transatlantic and a fair bit of general cruising, including some extremely windy weather in Greece.  They have lasted very well.  Only now am I thinking that a new mainsail is a good idea. Mostly because of the fact that it is battened and is getting tricky to furl…..I would not consider any other sail material…..

Thus have ordered a new Hydranet mainsail from Q sails in Turkey. It has been completed and is waiting for my return to Turkey in the spring. I decided to order it without the vertical battens…..As a matter of courtesy to Q sails, they quoted a competitive price and at all times kept me informed of a slight delay in the supply of the material from Germany due to supply problems further up the chain. The sail was ready two weeks later than scheduled….no big deal. 

It will be interesting to lay the new on top of the old one to see just how much area I lose. If I am happy then I will get a new mizzen and genoa from them.

My penny’s worth

I will give you my opinion regarding QUESTION 1:
A54s came with HydraNet sailcloth made by Dimension Polyant, Germany. They were constructed in a TriRadial pattern and had vertical battens. The early 54 HydraNet sails were made by Deme Sails, and later were made by Incidence Sails. I have seen numerous 54s from early (2005) to late model 54s. I have not seen HydraNet "lose its dimensional stability after a few years (maybe as short as 3-4 years), firstly becoming soft to handle, and then baggy." 

I have seen serious damage to HydraNet caused by jamming and chafing of the mainsail vertical battens. Judy and I purchased HydraNet sails in a TriRadial construction in 2012. We experienced none of what you mentioned and I believe that the current owner of BeBe is still satisfied with the sails. HydraNet in a TriRadial construction will cost about 20-50% more than a high-quality Dacron Hybrid (like Dimension Polyant ProRadial) in a TriRadial construction. I believe that you will get far more than 50% life from HydraNet. However, you should get significantly more life from sails made from ProRadial in a TriRadial construction versus Crosscut Dacron sails. Crosscut construction has comparatively large pieces of sailcloth which because of their size, stretching will cause deformity and reduction in performance of the sail beginning at about 5 years. I believe laminates are not for cruising boats. Most sailcloth manufacturers will tell you to expect delamination in 5 years or less.

I recommend that you consider the 3 qualities of sails offered by Incidence Sails (Amel OEM Sailmaker). I negotiated an 18% discount when you order a full set, or 15% when ordering less than a full set. The prices in the following brochure are before the above discounts. Reduce the prices in the brochure by the appropriate discount. Each quality in this brochure is worthwhile, but do not expect the beginning quality to perform as long as the best quality.


If owners of other Amel models are interested in the Incidence Sail information:

Re: Mounting semy flex solar panels on the deck

Bill Kinney
 

I'll double up on Bill R's comment about screws and wet core!  Screws CAN be done safely, but it has to be done correctly.  Just driving screws into the deck WILL cause serious problems.  

Given the choices you listed, I would 100% go with tape, because it is reversible without TOO much hassle.  Just be sure that the tape will work on the texture deck surface.

Re: Check your GPS / AIS devices. Some of them failed on Jan 2, 2022 due to the "GPS Rollover" bug

David Crisp
 

With regards GP90 I can confirm Nick's message as I too have been in touch with Furuno UK about my GP90. 

FYI, I have a Furuno NavNet vx2 and RDP149, along with Raymarine AIS700 and Icom IC-M506 DSC radio, the AIS and DSC have their own internal GPS.  I'm not aboard at the moment but last season the Furuno vx2 displayed the track data from the AIS700 just fine.  I might try replacing the GP90 GPS data feed into the Furuno vx2 with the AIS GPS data output but I'm not confident it will work - from my VERY limited understanding I don't think the Raymarine AIS outputs the correct GPS sentence format.

If the Furuno technician is correct that the GP90 will provide good GPS position to the vx2 albeit incorrectly dated that's good enough for me and my modest explorations around Greece/Turkey.  I use the Furuno vx2 and chart plotter primarily to display AIS and radar data and as a backup to an iPad (with its own GPS) running Navionics.  Date stamping of tracks on the Furuno is not important to me.

In case it's of use here's the full text of the info' I got from Furuno:
"I think it best we start with the GP90, the GP90 should start working for outputting position data by carrying out the cold start procedure on the same article referenced. The date will be incorrect still but to my knowledge the position should still be correct and work as normal it just means things such as tracks will be recorded with incorrect date stamp, if the GP90 is feeding a DSC radio this could also cause issues as the incorrect date would be output in case of a distress alert.
I assume the VX2 unit already has the AIS interfaced so I presume the software is new enough to not require the interface, if you could confirm the VX2 software though it would enable me to have a better guess from my side. I have attached for your reference a picture of how to see what software version you have installed with the unit boots up and the software history of the VX2 unit which shows since V1.08 the need for a interface for a separate AIS interface was removed and handled in software on the VX2 itself. [I have attachments to this message]
Taking GPS data from a AIS into a unit as old the the VX2 is kind of unknown and certainly never tested with a competitors unit, please see possible set backs and you wont know until its been tested I am afraid:
BAUD rate - The AIS units normally speak at 38.4K BAUD and GPS is normally set to 4.8K BAUD, the VX2 may struggle to accept GPS data at this speed its never been tested.
Talker ID - NMEA0183 data has a talker ID stamp at the beginning so a typical GPS sentence structure is some thing like '$GPGLL,5051.7847,N,00118.7023,W,132236,V' and as you can see the beginning of the sentence starts with GP, the GP stands for GPS and denotes the source device. A typical AIS sentence looks like ' !AIVDM,1,1,,B,1CgWDt0000NGulhU?AAWv3;<0D1O,0*5A' so I am not sure the VX2 unit will decode GPS information in this format.
The GP320B was a very popular GPS to have fitted to the VX2 units and the sentences output on NMEA0183 were DTM/GGA/GLL/RMC/VTG/ZDA as per the attached document, if the Raymarine AIS can output these with a GP talker ID then this will be you best chance of getting it working assuming the VX2 can take GPS info from this device in mixed format at 38.4K BAUD. In the case of a Furuno AIS we have a proprietary data sentence which carries position data  over to the unit so we don't see the issue and have by design made our units compatible with each other."

 

Nick, looks like our boats are in the same place - I'm hauled out in Ionian Marine, hoping to get back late April.  Be great to meet up.

Re: Mounting semy flex solar panels on the deck

 

My Rule: Regardless of what you are mounting on the deck of an Amel, never penetrate the deck with a drill or screw unless you are an expert at protecting the balsa core. I have seen far too many Amels ruined with wet balsa cores because someone wanted to penetrate the deck.

Re: Fixed Prop installation.

 

Partial answer:

The shaft is tapered with a key. The fixed propeller is also tapered. A tapered-shaft propeller will almost always need a prop-puller to remove. The AutoProp puller is not made for the fixed propeller.

In terms of performance, someone else will need to answer, but I am sure there is a difference and I am sure how much of a difference is a matter of opinion. Check here for more information: https://www.bruntonspropellers.com/autoprop

Bill is correct, but I have a yard and a half on my Santorin - 54” on a 46’ boat. It fits exactly on the Amel pole. Anything smaller is not quite proportional in my humble opinion.

Re: Check your GPS / AIS devices. Some of them failed on Jan 2, 2022 due to the "GPS Rollover" bug

Nick Newington
 

Hi All,

I have  a Feruno GP 90 GPS. Only one of the data ports works. I have been keeping my eye out for a GPS 150 on eBay, but have not had any luck. So I phoned Feruno in the UK to ask about a repair and the roll over.

The technician suggested I buy an Actisense buffer. You connect it to the single data port that works and can connect up to six devices to it. It keeps each device separate. He told me that there were problems with multiple ports on GPS’s in general and the Actisense was a better solution. He said something about a common ground between the various devices, eg VHF, SSB, Plotter was the route cause of the failure.

So I have ordered one. 

As for the roll over he said only the date would be 20 years out, but position would be fine. Since I only have an AIS receiver it is not a problem.

Happy new year

Hi Peter,

The GP-39 is available here in Australia from a number of chandlers.
Some big differences to GP-90 - it's a lot smaller, so you'll need to reduce the size of the hole, and it has only one NMEA0183 port and one USB port so you'll have to reconfigure how you send the GPS signal to the devices your GP-90 is connected to.
 
I'm curious about this date rollover issue.
According to Furuno, a cold start will reset the device and the position information will be correct, but it will display the wrong date.
Correct me if I'm wrong anyone, but I don't think the date is actually used by anything my GP-90 GPS is connected to.
UTC is contained in some NMEA0183 sentences, RMB for example, but is this calculated in the Furuno, or does it come from the satellites?
I don't know the answer to that and I can't get to the boat to see what effect this wrong date has.

Does anyone know off the top of their head the dimensions of the ensign suitable for the pole.

Many thanks

Richie

Mango rudder post packing size

Arlo
 

Hello, quick question for my fellow Mango owners. What is the thickness 8mm or 10mm or ... for the rudder post packing for an Amel Mango. (I have a 1985 Mango hull #46). I searched this forum and found lots of details on the SM's but not for the Mango.

I thought I sent this ages ago..but just found it in drafts.
Thank you all for your insights. They were very helpful indeed.


Re: Check your GPS / AIS devices. Some of them failed on Jan 2, 2022 due to the "GPS Rollover" bug

Hi all,

I have  Furuno GP90 with wrong date and this summer it was working properly but only the date. I’m planning to install a GP39 with  an intermediate box ( local Furuno dealer support) to connect (different plugs cables) the device to the actual navnet network as before with GP90. Note: my GP90 display has humidity inside, so…

In doubt for my AIS ICOM MA 500TR (this summer it was fine and now I’m not on board) I asked to ICOM UK if may I have any problem with new update rollover. Answer: no news about and , any way, with wrong date there is no problem for the system (CPA, TCPA, ecc). Only wrong date.

Buon Vento

Alan,

I experienced the "Frist Rollover" with Y2k and the Furuno GP-80 in a SM. The reboot solved everything except the date and the date was not used with any of my connected devices which included AIS "B." At the time I was using OpenCPN for chart plotting and it was not affected.

Hi Peter,

The GP-39 is available here in Australia from a number of chandlers.
Some big differences to GP-90 - it's a lot smaller, so you'll need to reduce the size of the hole, and it has only one NMEA0183 port and one USB port so you'll have to reconfigure how you send the GPS signal to the devices your GP-90 is connected to.
 
I'm curious about this date rollover issue.
According to Furuno, a cold start will reset the device and the position information will be correct, but it will display the wrong date.
Correct me if I'm wrong anyone, but I don't think the date is actually used by anything my GP-90 GPS is connected to.
UTC is contained in some NMEA0183 sentences, RMB for example, but is this calculated in the Furuno, or does it come from the satellites?
I don't know the answer to that and I can't get to the boat to see what effect this wrong date has.

Every boat is setup differently, but our GP-150 feeds our VHF and SSB (when we had it connected). I presume if you send a DSC distress call, there is a timestamp on it. I know for a fact that my connected iCOM vhf displays the incorrect date.

 

For the AIS, it simply stops transmitting when it gets an invalid timestamp, as mentioned before. Cannot coldstart the FA-50 to fix it.

 

I would believe that since GPS is a source of very-very-very precise time, most devices that receive GPS (either directly or through NMEA sentences) would use GPS time information to set the device time versus have a secondary clock that is subject to drift.

 

I know that with the Garmin devices that have the rollover issue, the problem is that gps signal gets weak and then can show incorrect position data. Seems this rollover bug creates unpredictable issues. Best solution is to google your devices and see if they have any issues with the rollover bug, Furuno or not.
