Mark,

This is an odd one...  Just by way of additional information, what was the nature of the failure of the main battery bank?  You have the original Volvo engine?

Display VDS 215 MDS - nav table A54

Dear Amelians,

did any of you have to replace the display on the navigation table?  
The manufacturer doesn't seem to produce this anymore.  
Are there alternative displays or other sources of supply for this?

It needs 2 VGA connections.
The diagonal of the opening is approx. 45cm / 17,5 inch.

Thx a lot for your hints.

Best regards

Hi Thomas,

I did consider the intermediate position case. Apart from the fact I’m still able to add it if required the reality is that I never used it in the time we’ve owned the boat. When rain comes in from behind I typically close the hatch all the way up. When the sailing is so bad I get to the point of closing the hatch because of potential waves I will close it completely anyway.
The new lock also makes closing and opening the hatch much faster and a one hand operation.

Cheers,

Arno

Darren an Karen,
We cut the sump (funnel part) of the tank outlet off. Then we extracted the hose, inserted and glassed in the FRP riser, through the inlet hole and glassed back in the the funnel part of the tank outlet.

Tom and Kristin,
Our solution was to fiberglass in a 1-1/2”OD x 1-1/4” ID FRP tube riser through the inlet hole. The tube went almost to the top of the tank inside. Works well.

I have a switch in the cabinet where the steering rack is located

I don’t know if it was original. I left the switch in place, but disconnected the relay that did the remote connection. I would just connect with jump leads if needed.

Maybe there is something like this in your setup that has failed?

Mark,
Can you reproduce the fault by attempting to start the engine while the house bank is turned off?
As Thomas mentioned, maybe you have a PO mod where something in the start/run circuits for the engine depend upon the 24V house circuit being online.

Hello Bill, hello Arno,

we are just leaving La Rochelle, I will respond tonight.

Nicolas took measures and pics of the first manifold too. He should be able to create a design of this too.

Hi Tom and others on this forum,

Kaz and I are newby owners of our Super Maramu #171 and this is our first post to this amazing forum

I found a similar issue with our holding tanks this morning, it looks like there was a solid pipe through the bottom of the tank which then had a 35-40mm flexible pipe connected to it on the inside of the tank which went up to the top of the tanks and then curved over to point back down.

In both tanks the pipes have broken off on the inside of the tank, I'm thinking of replacing the pipe going through the bottom of the tank with a solid bronze pipe going up to near the top of the tank as in the modification suggested in this PDF

I like the idea of going into the side of the tank at the side as well, but do find going in the bottom neater.

I'd like to get the old flexible pipe out of the tanks as well, not sure if this is possible without cutting an inspection hole in the tank.

I'd be interested to hear about how you go about your modification.

Kind Regards

One goal of the project would be to make it easier to maintain. If the idea is to have the black water enter at the top of the tank, I'm wondering if anyone has moved the inlet from the bottom of the tank to the upper side. This would have the benefit of allowing the hose to run outside of the tank and turn left, dramatically simplifying clearing clogs.

Anyway, I want to consider all possibilities before I open this can of worms.

I would venture to think the idea was to be able to have intermediate positions. Not that we have made use of it much, but maybe one day...

One handed operation sounds great, though

Personally, the only thing I don't like about the Amel system is that the door can free-fall all the way.  It would have been great to have some kind of piston in the design which supported the weight of the door, and either lowered it in a controlled way, or required a little downward pressure to open. As if our boats are not complex enough, right!

I think most people looking at your mechanism for the first time would find it obvious to operate, and probably not let the door drop.

Re: House Bank vs. Engine Start

Thomas Kleman
 

The house bank and start battery should be completely separate. But you've had not 1 but 2 coincidences. On your boat, the state of the house bank seems to influence the start circuit. Before I did anything (like take the boat somewhere), I would label and test the entire start circuit. Maybe a previous owner made a "modification". 

It could also be 2 problems; you may have a problem in the ignition/starter circuit, the start stop solenoid, or something else. 

Sounds like a long weekend with a multimeter.
Good luck.

The start battery was a bit over 12 Volt, I didn’t check it at the starter. Once I replaced the house bank everything worked fine, which I fine odd.

House Bank vs. Engine Start

Mark Garver
 

Okay, so recently I had a main bank failure, but what is disturbing is that the engine wouldn’t start. Confusing as I have a dedicated engine start battery, same for the generator. Has anyone experienced this, or have any idea why? Is there a way around this? I can’t imagine this happening in an anchorage, or at sea.

Thanks,

Re: solar panel

Dean Gillies
 

Hi folks,
Interesting that people comment about getting more output than their panel ratings.

All solar panels have the capability to produce more than their rated output.  This is not some some magic which belongs to particular brands of panel.
It is almost entirely the result of the energy delivered by the sun on the panel and the alignment angle of the panel to the sun.  (There are also second order losses due to wiring, power conversion and temperature) 

Panels are rated by all manufacturers according to standard test conditions with a reference insolation power of 1000W/sqm.  After production, the panels are subjected to exactly this level of insolation (artificially and accurately produced), directly on the face of the panel and the output power is measured. The panels are then sorted into groups depending upon how much power they produce.  This is why the manufacturers have a range of different panel power ratings, say 390W, 395W, 400W and 405W, on their top of the range products.  There is no difference in the production process, but there is a natural tolerance spread.  This way of grouping panels tends to be more common with newer panels at the highest end of performance. Its a competitive thing because they want to quote the highest performance/efficiency number to beat the competition, so will advertise heavily, for example, the 405W performance. It may be that only 1% of the produced panels reach this level, and so they are also very expensive.  As technology moves on, the manufacturers keep producing these panels, but after a while they are not at the bleeding edge of performance, and end up being rated with only one power, which is generally the minimum achieved in production. They will also move to sample testing only, which keeps the price competitive.

In the real world, the insolation level is not always 1000W/sqm and of course our panels are not perfectly aligned to the solar axis.  Sometimes the insolation from the sun is much more than 1000W/sqm and if our panels happen to be well aligned at that time then they will of course produce more than their rated power.  Unfortunately, most of the time they produce less !    

The highest levels of efficiency at the moment for commercially available panels is around 22-23%.  That means that a top performing panel of area 1sqm when subjected to a perfectly aligned reference insolation power of 1000W/sqm, will produce 220-230W. Beware of panels advertising more than 230W/sqm performance, they don't exist yet.

If you stick to a reputable manufacturer, you should receive an accurately calibrated product which produces less than rated output most of the time, but sometimes if you are in the right place and you align your panel properly, you might get 10, 20, 30% more than rated output.

I really need to get back to my boat!

My aft head holding tank riser has separated from the lower part of the copper fitting. So inflow to the holding tank enters at the bottom of the tank. Despite this, there is no leaking from the fitting.
