Ron, Thank You, but I just ordered a new hose from the company that Bill sent me a link to. They are in Philadelphia , maybe 75 miles and they will ship it. The more local outfit wanted $80 per fitting ,plus hose and labor.

Pat, if I recall you’re on the East Coast of the US, correct? If so try a company by the strange name of Collilower. They have over 30 branches from New York down to Florida I believe. A few months ago I had to make up a new set of hydraulic lines for my steering, and they did a marvelous job with stainless steel fittings.

Pat,

I can assure you that there is nothing at all "special" about the prefilters used for a watermater. A 5 micron rated filter will do fine. If you have dual filter housings in series, a 20 or 25 micron in the first chamber will catch the "big" stuff.  You'll generally do better with the pleated paper elements than the filament wound ones, but it's not critical.

I am betting that the guy who told you you needed "special" watermaker prefilters just happened to have some of these magic filters he was happy to sell you. I'd take all the advice you got from him with a very large dose of salt.

Although they are not expensive, in an emergency you can reuse them at least once or twice.  Put a line down the filter, tie a stopper knot , and tow them behind the boat.  The resulting "backwards" flow through the element does a good job at cleaning them if they are not too far gone.

Re: Additional webbing above tack on Q-Sails Genoa Question

Michael & Robyn
 

Hi Bill,

I see your point on the halyard tension. I will pay more attention to this fact when we mount the Genoa after hurricane season. The electrical winches are so powerful that a moment of looking at the top part of the sail may be a moment too long and the tension of the foot is causing the luff tape to come out.
Our sail maker knew about the concept and will add the extra webbing.

Thank Y'ALL

Hi Pat,
I stock up on these 5 and 20 micron from Amazon. I have the same watermaker as you. All the best to Diane. 


Watermaker

Patrick McAneny
 

A couple of questions, I was told by a water maker dealer in Antigua ,that I need to use special prefilters designed for watermakers .I had up to that point used filter elements I bought at Lowes , 5 and 25 microns. Was he just trying to sell me some expensive elements ,or was he telling me the truth and the prefilters  need to be for water makers specifically ?
Secondly , I have the 160l/hr. model ,could someone remind me of the size elements I need to purchase , and suggest a good place to purchase them in the US.
Thank You,

Re: What to do with LiFePO4 batteries when the boat is layed up?

Dean Gillies
 

Hi Jeorg,
With your existing system, it looks like you only have two options. Either leave powered on float or disconnect completely and have someone attend the boat every 3 months and top them up.

The reason they only last 6 months is that they contain internally embedded electronics which consume some small amount of power. All LFP batteries with internal BMS will have this same problem.  The cells themselves last much longer (years) without needing topped up, but any batteries with internal BMS will always drain down slowly.

As to which option is preferable, my personal choice would be to have them topped up periodically. LFP do not like to be floated at high states of charge for long periods as it does negatively impact their life.

In my system I have 115Ah of Lead Acid in parallel with my LFP cells, so my wintering strategy involves dropping the LFP cells to about 60% SOC and disconnecting them completely from the system and the (external) BMS.  Unfortunately this is not possible if you have batteries with an internal BMS. 

Sorry, not much help!

Paul, why choose 12 volt batteries for a 24 volt circuit?  2 main reasons for Victron models (the same problem with Mastervolt batteries): 24 volt batteries do not fit in the battery compartment when standing, they must be laid on their side which is not recommended and  in this case we can only put 2 of 200Ah which is lower than the original capacity, on the other hand the higher weight complicates handling.

Bonjour Juan,
it’s easy to control the Mastervolt alternator with external Alpha pro regulator using a Victron Battery-protect (the smallest), in position 7 it is used as a control relay by the Victron Ve-bms.  The consumption is 1.5 mA completely compatible with the maximum authorized current of 10 mA of the Ve-bms.  A second, ordinary relay, powered by the ignition key, will only activate it when the engine is running (+ a manual switch for security).  The bluetooth version of this Battery Protect allows you to control the charge with a smartphone (stop and start).  When I sail with the engine, as soon as the voltage of the batteries reaches 27.6 v (95-98% of charge) I stop the alternator with the smartphone so as not to keep the batteries at a high voltage for too long (the duration of  absorption of 28.5 v is 4 h with the Alpha pro).  For the other loads, if they are Victrons they can be managed by the Ve-bms otherwise either they have a remote control and another small BP will be used or there is none and a Battery protect of suitable power can be put  on the charging cables.  Note that the Ve-bms has a maximum control of 10 mA for the charge and 2 amps for the load (+ 50 mA for the pre-discharge alarm).  A bluetooth BMV with audible alarm informs as soon as the voltage is high or low (adjustable). The smartphone will check each battery cell and you can stop the charge or the load if necessary.
For the battery charger, if you are in the boat, you can drive it yourself with the  bmv and stop it as soon as the charge is finished.
