Sailing higher latitudes

Orion Martin
 

Hello everyone,

Just a quick question to see if anyone has had experience sailing higher latitudes, even as far as the Antarctic peninsula? I recall seeing a photo of an Amel Super Maramu in Svalbard, and my interest was piqued when Stefan asked about the prospect of installing a diesel heater to an SM. At some point I would like to sail to higher latitudes, and I'm fully aware of the need to look out for and push away bergy bits and growlers (small ice blocks) from the yacht as it can abrade (or worse damage irreparably) the exterior of a SM. However, I was concerned about the comfort level considering the SM is not insulated, so a diesel heater would be the absolute minimum required to endure a stint in higher latitudes.

Any thoughts or experience shared is most appreciated.

That sounds like a great addition to anyone's Amel !

Hello Nick. Thanks. Maybe you or Karen will recognize the key.

Great!
Thank you Bill.
Hopefully we make the contract for SM 351 shortly.

Re: A54 fridge circulation pump

Mohammad Shirloo
 

Hi Scott;

 

We’re currently in the Med, so we’re on board full time for about 5 months every year. The fridges are obviously on all the time. We typically run two of the fridges and do not typically have a freezer on. I agree that the system will be working harder in the Caribbean and tropical conditions and are working closer to their design limits.

 

One of the reasons we selected an Amel, was because it had been tested over decades in conditions we expected to experience. I cannot comment based on personal experience about tropical conditions, since we have not experienced it with our Amel. I would look into the experience of all other Amel owners who have experienced the same conditions and if a significant percentage were experiencing what you and Arno have experienced, then I would conclude that there may be some design issues with the system. Otherwise I would suspect some other issue that may be unique to us. I typically suspect the design and component issues as a last resource, after I have eliminated all other possibilities.

 

Sorry that I cannot be of much more specific help, just another point of view.

 

Happy Sailing;

Mohammad,

Do you live aboard full-time? Arno and I do and our experiences are similar. In tropical heat and 2 fridges and a freezer running, at any given time, it's very likely one of the compressors is running which means the pump is running. 

I would guess my pump runs 80+ % duty cycle. The Frigoboat pump interface really should have the ability to coordinate the compressor operation "schedule".

My understanding, confirmed by long discussions with pump engineers at Marco, is that brushes on any DC electric motor last 2500 hours on average and in the best circumstances 5000 hours. With the near continuous duty, the Flojet pumps get quite warm, which accelerates brush wear. If you take my experience with 6 month motor life and multiply it out: 180days * 24 hours a day * .8 duty cycle = 3456 hours, which is right within spec.

If your pump lasts 11 years in the same use case as Arno and myself, that would mean it's lasted over 75,000 hours!

Even March pumps, which are brushless, are only rated for 50,000 hours. But sadly for my setup, the March rep told me it wouldn't work since their pumps won't self-prime, confirmed by Arno's testing. I would really love to retain the self-priming capability of the Flojet pump but get a brushless motor on it, like Oliver has done.

Re: A54 fridge circulation pump

Hi Arno;

We have never had any issues with these pumps. We are still on the original pump after 11 years and have the backup if the original dies.

Given the variant in life span and longevity that some are seeing in the same pump and design, I would suspect other potential problem areas that lead to the early demise of the pump. These may include flow restriction, differences in heat, moisture, in the operating environment, demand and cycling, etc.

I know this may not be very specific and helpful, but I usually suspect the mechanical units in the system that have functioned well in so many other identical installation, last.

Respectfully;

Hi Scott,

Great to hear I’m not the only one that has trouble with these pumps. I asked Flojet about this and they simply do not carry a brushless variant of this pump. I did have a look at a few other pumps that look very nice on paper (magnetic-drive and brushless). The two I tested (both centrifugal) did not supply enough pressure to overcome the resistance in the hoses/pipes. I now have al lot of pumps to do other stuff with :-(

Currently running a 12V/1.5A Flojet Quiet Quad but I’m sure it will die within a year despite the claim to be for continuous duty. It does stay cooler then the “official” Frigoboat pump that is actually a 24V shower-pump running at 12V. The pressure of the 12V model is adequate.

So I’m also interested in a more resilient solution to this problem.

I would be concerned leaving the vent open on the Vetus because in the past, we've had to start the engine somewhat unexpectedly.

I fired up the engine and quickly got us around the right way. 

Might be a bit more complicated if you're dumping seawater and CO into the engine room.

I'll stick to running it for 15 minutes daily and enjoy the hot water showers!

Oliver, 

Could you show us a photo of this setup? A picture is worth a million words.

My second Flojet pump just died. With two fridges and a freezer running, the lifetime is 6 months, max. Upon disassembly, it appears the brushes have worn out and the commutator is heavily scored - looks like the Grand Canyon. I would love to retain the diaphragm pump but replace the motor as you have.

Sounds like I'm worrying about something that hasn't been an issue.  Guess I'll leave well enough alone.

Thanks,

Hi Kent,

I thought I had replied but it seems to be lost somewhere. I have a large diameter stainless tube at the end of the exhaust just inside the hull and the exhaust is attached to that. I assume the flap is in there. I have never gone looking. I think we are wise to follow Amel advice as to starting the engine daily. Those of us with wind and solar who don't need the genset  every day would likewise be sensible to do a daily start.

Regards

and best wishes for the New Year

Hi Danny,
So do we have a flap valve somewhere in the system?  I thought it was supposed to be at the muffler.  Do we have one at the exhaust exit thru-hull?
If not, should we?

I have been aware of the fact that water can backflow into the engine on a port tack, and do run the engine and generator a couple times a day while at sea and have had no problems so far.
