Re: Size of main anchor for Super Maramu

Arnold Mente
 

Hi everyone,
I am now following the discussion about the anchor and the type for a few days. I have had the following anchor types in my 35 years of sailing. CQR, Delta, Bügel and Rocna. I currently have the Rocna 33 kg on my SM. I also drove it on my Benetau 523. I think the discussion is going in the wrong direction. The connection between anchor and chain length and chain dimension is not considered. On a sailing yacht for all areas should be 100 - 120m. The chain length is essential for the horizontal forces on a well buried anchor. Only this interaction is essential for the holding force. You can also use 100 kg anchors and they will break out if there is not enough chain.

Hello all.
I am one of those planning to change my current 30 Kg. stainless steel Bugel for a 48 Kg. galvanized Mantus. I confess that I have doubts between Mantus and Rocna because I very much like both. The reason for this change is because I drag anchor in a 35-40 knots wind, although I had 40 meters of chain on a four or five meters mud depth.
But I am open to comments from you, since I don't think I am among the most experienced sailors in this group...

I was not going to interject into the anchor conversation, as this topic is akin to religion.
The Mantus is of the latest designs in anchors. Very good. I worry a bit about the original style, in that it depends on the tensile strength of the four bolts holding it together. This is a worry. In addition, there is a frequency of bent shanks. The shank is thinner than competing anchors, and doesn’t tolerate a bending load very well. 
Mantus fixed these issues with their new design anchor. Check it out.

Re: Size of main anchor for Super Maramu

With a sandy bottom most anchors work very well the question is how do they perform when you’re forced to anchor in either San Luis coral or heavily grass bottoms to me and Achor that would improve by chance of getting a good stick in those conditions using proper anchoring technique would be a valuable asset

Re: A54 fridge circulation pump

Oliver Henrichsen, SV Vela Nautica
 

Hello, 

My pump is based on a brushless motor, not a stepper motor. 

You asked me about building an "adapter" from old fridge system to VESC conrolled brushless pump. 

My adapter replaces the original controll box. 

It has the following features:

1. If any fridge freezer signals cooling needs, it activates the VESC brushless pump.

2. Rpm can be regulated from 0 to 100%

3. Pump can be stopped by switch

4. LED display of operation. Flash every 10 sec in standby. 
Flasch every sec when pump is active. 

5. Energy consumption. In standby some mycro uA. In operation about   15 mA.

6. Connections
- 24 Volt
- serial port VESC
- signal wires coming from fridges freezers

As I understand, you ordered the VESC and the brushless motor yourself? 

Please contact me by my email, I like to send you a Video how the Pump is setup.

The mango is comparable to a maramu, but slightly larger.

The difference between a mango and super maramu depends, since later mango’s can also have electrical furling and the bowthruster.

Aside from that, the mango has a regular propshaft (which I find an advantage) and a different hullshape, especially aft. Systems are 12v. Prices of Mango’s are more favorable. 

In general many features of the mango are also present in the super maramu.

Re: A54 fridge circulation pump

Hope the new pump works out, it would be nice to find a substitute for the Flojet.  When you get it installed if you have a question about the flow due to the head pressure measure the discharge rate where it exits the hull and see if the volume is adequate.  Good luck.

Re: Converting my Amel 54 to lithium batteries: what I did, what I like and what I don't like (after one year of full time live aboard use)

Jamie Wendell
 

Hello Scott, I realize your posting was from awhile ago, but I am getting ready to convert my Amel 54 (Phantom) to LifePO4 batteries. I have read your "dissertation" with great interest and am interested in getting an update from you before I make the plunge.
Have you been able to resolve all of the "problems" you noted? By the way, here is what I am planning to install with my electrical contractor:
 
(12) 24-Volt (50 AH) Battle Born LIFePo4 Batteries
(2) Victron Multiplus 24/3000/70-16
(2) Victron Smart BT Dongle
(1) MK3-USB Adapter
(1) Mastervolt Alpha III Regulator
(1) Victron BMV-712 Smart Meter w/Temp Sensor

Since I already have a 3kVA inverter, I did not want to upgrade to a Quattro or a higher capacity Muliplus unit. That would have forced me to do a lot of wire upgrades, and I think 3kVA will suit my needs. With the lithiums, however, I have decided to split my AC bus into 2 columns - 1 side for inverter-capable and the other for high-current loads, such as my 230V(only) watermaker, dive compressor, and saloon AC. We decided on 2 inverter/chargers for redundancy, where one unit will be set up for charge only. That way I can charge and invert simultaneously, and even provide 50hz power when connected to 60hz shore power in the US. I intend to use the existing battery charger circuits to feed the Multiplus units, so as to maintain the flexibility Amel provided originally. The incoming shore/generator ATS will remain as is.

I also have at least one possible solution for you regarding some of the "problems" you indicated you still had to resolve. Maybe you have already found the solution, but I have used the following Elk Products relay very successfully, and I'll bet it will work for your Mastervolt reg disconnect. This is what I intend to use.

ELK-924

The ELK-924 Sensitive Relay module features DPDT (Form "C") dry contacts for general purpose switching of devices or high current loads. It operates on 12 or 24 volts DC and can be triggered with a negative or positive input at an incredible low current of only 1 milliamp. Also available in a 4 pack (ELK-9244) which is packaged as 4 relay modules grouped on a pre-scored break-off circuit board.

Hope all is well with you.

I cannot afford to piss him and his support group off so I leave it alone but I can tell you, absolutely that Amel did not install those lock downs.

That said, BeBe SM 387 had Amel installed latches and they were not Perko.

Re: Size of main anchor for Super Maramu

Ross Hickey & Donna Hammond
 

Hi Steven,

We are still waiting for delivery of our 47kg Mantus anchor, but the research I did on the working load of the 1200W Lofrans winch provided proof that the winch will handle raising the anchor and chain, providing good anchoring techniques are used ie motoring up to the anchor and breaking out the anchor by motoring over it rather than using the winch.

The maximum pulling power of the 1200W Lofrans winch is well with in the limits of raising the weight of 80m of 10mm chain and 47kg anchor, should you ever require to do this, ie drag anchor into deeper water. I will test our winch however to be certain as part of the trials once we have have our new anchor on board.

We will not change our current 10mm anchor chain.

Kind regards

Hi Steve,

In my opinion a 47kg Mantus is overkill. Remember that the system is as strong as its weakest link. Pay particular attention to swivels and other connectors. 

I would suggest looking for something around 40kg as a maximum. For my 54 I chose a 37kg Spade anchor. When it is well set I can not budge it with a lot of power, I also went for new 10mm Grade 70 chain rather than the grade 40 and a massive Mantus swivel and special shackle that is as strong as the grade 70 chain. The original 30kg WASI is now a second anchor, but in my view it is undersized and a bit old fashioned. It does however fit well on the port roller, and is ready to go, and more or less manageable from a dinghy.

Obviously there is a good argument for a massive anchor, but as you point out you must consider the windlass and the rest of the system.

All in my humble opinion.

I am about to purchase a new Mantus 47 kg (105lb) galvanised anchor for my Super Maramu, which is the same size as that on SvDelos, but quite large for an SM which seem to usually have anchors around 30kg. Unfortunately, I have been unable to find out how Delos have got on with it, but most experienced sailors say it is better to go bigger for the extra security.  With an all chain rode, 10mm I think, am I putting too much strain on the windlass on a daily basis? I would appreciate your thoughts and recommendations.
