Re: Bow Thruster Amps rating.

The bow thruster is If I recall correctly is 10 HP. 10 hp x 746 watts is 7460 watts without any loss .I would add at east 10% for that, 8200 watts/24=342 amps.
That would be dismissing and loss in the feed to the motor. If you look at the motor you will see multiple heavy gauge wires going to the motor.

Hi- maybe someone can help me understand... The Super Maramu 2k Manual shows that the bow thruster draws 7000W and 510A at 24V.  Is this correct?  If so, how does the math work out?  W=VxA is violated AND no reasonable wire size is rated for that 24v DC..\

 I am trying to properly fuse my battery bank and this beast is the crux.

Re: Bow Thruster Amps rating.

 

Chris,

We shouldn't get into a discussion of what is right or wrong, but rather work to help you. Maybe the math is French math or Texan math, but it will draw as much as around 500 amps. Additionally, the bow thruster wire from the battery switch to the bow thruster is connected to the battery side of the switch. 

You might consider a batter terminal fuse for each battery. That would be my suggestion. In addition, you might also consider a 500 amp time-delay fuse located near the bus bar located near the bow thruster at the termination of the wire from the battery switch.

Re: Main Furler - Sail stuck / jammed

Thank You Bill, Ian and Courtney,

Tried all already, except of releasing the gear and try manually - will give it a go tomorrow morning and will update.


Re: Main Furler - Sail stuck / jammed

 

You have a problem that probably includes the sail twisted backwards on the foil. The guy might be a good electrician, but keep him off the boat. 

Drop the motor and gearbox about 30mm by loosening the 4 bolts  Untie the mainsail from the outhaul. While pulling on the clew of the mainsail, use a winch handle in the manual furler turning a little clockwise and anticlockwise until you have all of the sail unfurled. You may have to go up the mast to pull the sail out. 

Best,

Hi Bill,

The motor is ok, and operational. the sail was opened with NO out hauling, and then closed again and then opened again by the electrician ALL within the mast without out hauling - what caused the sail now to be 'messy folded' in the mast.


Re: Main Furler - Sail stuck / jammed

Courtney Gorman
 

Start by furling as tightly as possible then streach the out haul loosen and repeat

Do as Bill says and use the winch handle, but on my previous boat (not AMEL) the furling main jammed a few times - usually when rolled too loosely. I found it helped to pull downwards hard on the leach of the sail. You may need to release or slacken the short rope on the clew first. It may help too if someone can reach up and push the sail/foil inwards (away from the mast slot). Good luck.

Re: Main Furler - Sail stuck / jammed

 

Is it stuck, or is there a blown circuit breaker?

If stuck, the furling foil can be released from the motor gearbox:

Hi Group,

When left the electrician for few mins to go through the main control panel (above the steering) in order to reinforce, clean up and do the contacts - he was playing too much with the main fuller button - from here I believe you can guess what happened...

Right now the sail is well stuck can't move in or out (closed position). Do anyone has an idea how to release?

It happened to me once previously but was 50% out so was able to shake the boom, then in / out few attempts and released. This time seem to be much more complicated.

Please any

Re: A question about coppercoat

ianjenkins1946 <ianjudyjenkins@hotmail.com>
 

Hi Paul,

We put Coppercoat on 10 years ago when we were in England .  In our first season we went up to Scotland and on to the Med and we have been in the Med ever since.

 We were disappointed in our first season as the hull stayed a sort of brown colour  ( as originally painted ) and we had some fouling. We then sanded very gently and have not looked back.

 We had some rust coming through on the iron keel after 5 years so we had  Coppercoat applied afresh  on that section by Cleopatra marina in Preveza in the Ionian. ( they did a very thorough job )

We now sail for 5 months of the year, April till June, coming ashore for July and August, then afloat in the autumn and ashore in the winter.

 Our Coppercoat is now green. The copper has really come through and is completely effective against fouling. Someone had told me that Coppercoat gets better as the years go by. I took that with a pinch of salt at the time but today I share that view.  After three months in the summer we can detect a slime on parts of the hull but it comes off with a sponge when we are swimming.  Med sea temperature in the summer can get up to 27c ( 80F) and was still at 24c  ( 75F) last week.
When we lift we are as clean as when we launch. 

 For us, with our limited number of months afloat, Coppercoat has delivered. For 33 years we antifouled, doing everything ourselves--sanding down, filling patches, painting etc etc. Now that our combined ages approach 143 ( Judy has just reached her 30's ) I look for every labour saving device to complement the best labour saving yacht we have ever owned. Coppercoat has proved one such.

Hi Paul,
I have gone 9 months and no problem. CopperCoat been on for over 3 years now.
On another issue. I have changed the the lifting pistons on my windscreen in preparation for replacement. Can’t get to Grenada yet. See photo. I put a centre attachment for easier closing. Calling it the “EZ Close” New pistons are each 150n. I have a 300n piston if anyone who has an early 54 with the single piston needs a replacement. I changed because I couldn’t get a 300n piston.

Hi all,

 

With Coppercoat, my understanding is that scraping should be done 2-4 times a year depending on where you are. My question is: does it matter of the hull is not scraped for an extended period, say 9-12 months? Would this make it any more difficult to clean the hull later? Or even be detrimental in any way?

Re: Differences between Super Maramu (SM) and Super Maramu 2000 (SM2000; SM2k)

Mark McGovern
 
Edited

Jim,

That's because there really is no one definitive list.  Although there was a definitive name change to Super Maramu 2000, some of the design changes were made BEFORE the name change and some were made after.  Throw in all the minor revisions made over the years, the engine changes, and the many different options offered by Amel (dive compressor, diesel heater, watermakers, comfort pack, etc.) and you will begin to see that while ALL SMs are all more alike than they are different, each individual one is a bit unique.  From a cost/joy of ownership standpoint, you will likely be happier with an early SM that has been lovingly and well maintained by her owner(s) vs an SM 2000 that has been neglected by her owner(s) for the last 15 years.

That said, here are a few links discussing the differences between an SM and the SM 2000:
