Re: Manual Bilge Pump

Check the hose connection, and then check the hose for leaks. I, and a couple of others on the forum have had to change the hose which hardens and cracks over the years. I dismantled my pump only to find the diaphragm and non return valves were fine. But it didn’t do any harm to clean the whole thing up!

Re: deck leak

 

Bill & Karen and everyone,

I love your sketch and simple explanation of potentially a serious issue. I will add a word of caution. Small cracks in the gelcoat of any Amel can possibly lead to a serious core moisture problem. 

How many of us have walked past a tiny crack without thinking through the potential of a serious repair? If you choose to do nothing, one day you might regret it. I suggest that at the very least, temporarily seal that crack until gelcoat repair can be done. The most common areas that I see cracks that will cause moisture penetration is near the aft lazarette and on the cockpit seats where something heavy has hit the area with force. The most common cause is damage from the bottom fin of an outboard engine. 

If you have created a small crack, don't wish for the best, do something.

Hello Amelians,

Here are our thoughts about this deck leak!

Any deck leak, no matter how small, in the main cabin of a Super Maramu is a serious issue that needs to be addressed RIGHT AWAY.  
This is the voice of painful experience. A TINY little salt line was all that alerted us to one of the biggest jobs we have had to do to our boat.

Here is why...

From the aft edge of the hatch in the main saloon forward, the deck is pretty standard balsa cored deck. 
Right behind the hatch, the deck surface rises about 3 inches, while the cabin ceiling height does not change. 
 
The cabin ceiling here is thin (4-6mm plywood) and there is an empty space between the cabin ceiling and the structural underside of the deck. 
If there is ANY leak into this space, the water is free to roll around, and will find a place to drip down probably quite remote from the actual source.

What makes this situation so serious, is the back edge of the balsa core on the forward deck is not sealed, and is exposed into this space. It will soak up that water, and rot.  This is a big expensive repair to do right.  

Leaks into this space can come from the traveler, but more likely is from the hatch in the main cabin.  

There is a hardwood frame around the hatch opening, and the hatch frame is screwed into this with wood screws.  
 A lot of force is applied to the screws that secure the hinge side of the frame.  
If one of these starts to leak, the wood saturates, and water is then deposited into that empty space between the sailing and the deck, and problems start.

Hi Guillaume,

On our SM (233), the manual bilge pump is a Henderson Mk 5 (now Whale).  The service kit part number for ours is AK8050.  The most likely failure is a hole in the diaphragm.

Denis Foster
 

Hello,

During research I found this particular cell balancing technique of FLASH Battery in Italy. Seems to have a lot of industrial applications/

What do you think of this .

Regards

Denis
 
 
 
 

FLASH BALANCING SYSTEM

 
 
 
 
 
 

The exclusive Flash Battery electronic balancing system is called the Flash Balancing System.

Traditional balancing systems apply resistance to the cells with the greatest charge in an attempt to “lower” them to the level of the lowest cell.

Although it’s a simple and economical method, it’s also extremely slow: 4 to 8 hours on average are required for balancing alone (in addition to the earlier charging step).

OUR FLASH BALANCING SYSTEM OFFERS MUCH HIGHER BALANCING POWER THAT IS APPLIED NOT ONLY AT THE END OF THE CYCLE, BUT ALSO ACTIVELY DURING DISCHARGE

This results in 20 times faster balancing without increasing overall recharge time to a significant extent.

Traditional balancing systems require a much longer time, so when they’re interrupted because the battery needs to be used, the result is a gradual reduction in available energy over time: vehicles and machines thus lose range at every cycle.

THE ULTRA-FAST BALANCING TIME OFFERED BY THE FLASH BALANCING SYSTEM DURING BOTH CHARGING AND DISCHARGING ELIMINATES THIS PROBLEM AND MAXIMISES RANGE.

If unexpected repairs are need, the Flash Balancing System makes it possible to add or replace cells throughout the life of the battery, which overcomes the limits of traditional systems in keeping the higher and lower-performing cells balanced.

Re: deck leak

James Alton
 

Bill and Karen,

    You know your stuff Bill, thanks for the alert on the exposed balsa core.  When it comes to balsa core, prevention of damage is certainly far preferable to replacement!  End grain balsa is a fantastic core material but balsa wood is considered “perishable” as compared to more durable species of wood.  Keep it dry and it can last almost forever but if it stays wet for long it can rot pretty quickly unfortunately. 

    I am not sure if my Maramu has the same exposed core issue in your alert but I would like to investigate and if so to seal it preemptively before damage occurs.  Can you tell me what has to be removed to inspect the area in question?  

Best of luck with the fishing and keep having fun you two!

Re: Bowthruster motor switch

 

I believe you had to do what we did when we ran into this problem.

Did you use a piece of pipe to put pressure on with the puller to press the shaft tube out of the bottom motor plate mount?

New Bowthruster motor
So, finally we managed to get the bowthruster apart. And for all, finding out why we couldn’t get the driveshaft down to it’s original position, ie some 20 mm lower.

We had a big issue with getting the flange loose from the driveshaft, finally we used a puller and the key was to put pressure on to the bearing and not to the driveshaft itself.

Once the flange was gone we could get the gearbox housing apart and could see why we couldn’t get the driveshaft all the way down to it’s original position.

As expected the sleeve with keyway had moved and the keys were not in place.

Hope this can help someone.

I´m attaching some pics and if someone is interested I have more.

Eno 4 burner Stove grate and standoffs

eric freedman
 

We have had a perpetual problem trying different methods of retaining the grate above the burners. We have the stove that came with the deluxe package on our SM2000. The grate does not stay in place . The plastic standoffs are worn and I wonder if anyone has had new ones fabricated out of stainless.  The other problem we have is that a frying pan will slip under the bar on the front of the stove. We have fabricated a piece of 1/2 inch dowel rod that is suspended from the front bar by cup hooks and held in place by seizing wire. Our solution is rather amateurish looking. Any better ideas?

Scott SV Tengah
 

Joerg,

As I mentioned before, I believe, it is recommended (and I do) charge to full once a month. That resets the battery monitor to 100% and also balances the batteries since for every battery I know, balancing only occurs when nearly full. That has to do with the very flat voltage vs. SOC curve. There's bottom balancing, too, but that's beyond my comfort level.

There is a significant difference between charging full once a month and keeping it full. The former is recommended, the latter is generally accepted to be detrimental with no known benefits.

An interesting tidbit from the manual for my MV batteries. One of the „events“ causing an alarm on the Masterbus system is that the batteries HAVE NOT been fully charged for a period - default 31 days:  „ Last time fully charged serves as an event source. To prevent damage the batteries must be charged to the full 100% regularly. It is a common misconception that Lithium- Ion batteries should not be fully charged.“

Re: Wind Vane Autopilot

Ian Park
 

I had a hydrovane on my Santorin. It was there when I bought it.  It worked well most of the time, but on occasions (especially downwind in a blow) it would veer off course badly and I would have to free the wheel to manually steer back. Also when we encountered sargasso weed crossing the Atlantic the vertical rudder collected the weed and could not work .
removing the rudder is awkward, but putting it on at sea even in light swell is very difficult. You do need a system for locking the steering wheel.

I have since removed it and sold it. On removal the gel coat on the stern has been worn away badly, and the holes elongated. I did have to tighten the six securing bolts on occasion. I think it would be preferable to add extra layers of glass inside the lazarette as well as the wooden supports on the outside. I did also change the penny washers for stainless steel backing plates. The lazarette on the Sn and I believe the SM is not the main stern bulkhead (its the bulkhead between the lazarette and the aft cabin). It seems to be a lighter build than the rest of the boat. It is also why it is recommended not to over tighten the back stays on the mizzen, other wise you will get hairline fractures where they are bolted on the stern.  I am happy with the prop shaft alternator which keeps the fridge, autopilot and instruments running without any battery drain. I carry a spare type 2 rotary drive which takes 10 minutes to swap over. I also have 200watts of solar panel on the aft rails which can be tilted towards the sun. I have never had my batteries drop below a 90% charge, and then only at anchor. 

But - I have not had a lightening strike.
